The sharp square outline of the princess is repeated by the halo, so the head reads as a bold, bright square on the finger.\u003c\/p\u003e\u003ch2\u003eAt a glance\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter stone:\u003c\/strong\u003e Princess cut lab grown diamond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCarat options:\u003c\/strong\u003e 2, 3, 4 and 5 carat center diamond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor and clarity:\u003c\/strong\u003e E color, VVS2 clarity, excellent cut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertificate:\u003c\/strong\u003e IGI report for the center diamond, included free\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSetting:\u003c\/strong\u003e Four V shaped corner claws inside a square halo\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccent stones:\u003c\/strong\u003e Round brilliant lab grown diamonds, about 1.3 mm, micro prong set in a square halo\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBand:\u003c\/strong\u003e Plain rounded band, approximately 2 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMetals:\u003c\/strong\u003e 925 sterling silver, 10K, 14K and 18K gold in yellow, rose and white\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing sizes:\u003c\/strong\u003e 1.5 to 13, including half sizes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMade:\u003c\/strong\u003e To order by hand in Surat, India\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eA square frame for a square diamond\u003c\/h2\u003e\u003cp\u003eA princess cut has four pointed corners, and those points are the part of the stone that needs protection. Each corner here sits in a \u003cstrong\u003eV shaped claw\u003c\/strong\u003e that wraps the tip, which is the standard, secure way to hold a princess while leaving all four sides open to the light.\u003c\/p\u003e\u003cp\u003eThe halo is a true square with sharp corners, set with a single row of round lab grown diamonds on micro prongs. It follows the outline of the center exactly, so the head keeps its geometric look and simply grows in size. The brilliant facets of the princess and the round halo stones sparkle in a similar way, which gives the top of the ring an even, lively surface of light.\u003c\/p\u003e\u003cp\u003eBelow the halo the ring is kept simple. The band is plain, rounded and slim, and the profile photograph shows the head lifted on an open four claw basket above it. That height lets light enter the center diamond from the sides, and keeps a flat space along the band for a wedding ring later.\u003c\/p\u003e\u003cp\u003eOne of the worn photographs shows three of these rings on one hand with different center sizes, which is a helpful way to compare how the square head scales before choosing a carat weight.\u003c\/p\u003e\u003ch2\u003eWhy the princess cut\u003c\/h2\u003e\u003cp\u003eThe princess cut is a square brilliant with sharp corners and a great deal of fire for its outline, the squarest of the bright cuts. It is one of the shapes we are asked for most often, and every princess we set is cut to excellent proportions and graded by IGI.\u003c\/p\u003e\u003ch2\u003eHow this ring differs from our other princess lab grown diamond rings\u003c\/h2\u003e\u003cp\u003eAmong our princess cut lab grown diamond rings, this is the square halo on a plain band. Our princess solitaires, bezel rings and knife edge rings have no halo, and our princess twisted and pave rings carry their small diamonds on the band. This listing is photographed with the largest center of its group, and its sister listings share the same design.\u003c\/p\u003e\u003ch2\u003eWhat a lab grown diamond is\u003c\/h2\u003e\u003cp\u003eA lab grown diamond is a real diamond. It is pure crystallized carbon with the same cubic crystal structure as a mined diamond, grown above ground by one of two methods: chemical vapor deposition, known as CVD, or high pressure high temperature growth, known as HPHT. The Federal Trade Commission in the United States recognizes it as a diamond, and the gem laboratories grade it on the same color, clarity and cut scales used for mined stones.\u003c\/p\u003e\u003cp\u003eHere is what that means for a ring you will wear every day:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness 10 on the Mohs scale.\u003c\/strong\u003e Nothing natural is harder. It will not scratch from ordinary wear and it keeps its polish for a lifetime.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRefractive index of 2.42 and dispersion of 0.044\u003c\/strong\u003e, identical to a mined diamond. The brilliance and fire are those of diamond because the stone is diamond.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIt tests as diamond.\u003c\/strong\u003e A standard diamond tester reads it as diamond. Only a gem laboratory with spectroscopic equipment can tell whether a diamond grew in the earth or in a laboratory, and that origin is written on the IGI report and laser inscribed on the girdle.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTraceable origin.\u003c\/strong\u003e A lab grown diamond comes from a known production run rather than a mine, with no mining footprint and a clear chain of custody.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eIt is not moissanite, not cubic zirconia and not a simulant. Those are different materials that only imitate the look of diamond. The difference between a lab grown diamond and a mined diamond is origin and price, not chemistry, optics or durability.\u003c\/p\u003e\u003ch2\u003eE color and VVS2 clarity\u003c\/h2\u003e\u003cp\u003eEvery center diamond we set is graded \u003cstrong\u003eE color\u003c\/strong\u003e and \u003cstrong\u003eVVS2 clarity\u003c\/strong\u003e, on every metal and every carat weight. E sits in the colorless range, one step below D, and looks icy white to the eye in any metal, including yellow and rose gold. VVS2 means very very slightly included: any inclusions are so small that a trained grader has difficulty finding them under ten times magnification, and nothing can be seen with the naked eye. Cut, polish and symmetry are graded excellent. Accent diamonds are matched to the same E color and VVS2 clarity, so the whole ring reads as one even white.\u003c\/p\u003e\u003ch2\u003eIGI certificate included free\u003c\/h2\u003e\u003cp\u003eThe center diamond comes with a grading report from IGI, the International Gemological Institute, one of the largest independent diamond grading laboratories in the world, with laboratories in Antwerp, New York, Mumbai and Surat. There is no extra charge for it on any metal or any carat weight. The report records the shape and cutting style, the measurements, the carat weight, the color grade, the clarity grade, the cut, polish and symmetry, and it states in writing that the stone is laboratory grown. The report number is laser inscribed on the girdle of the diamond, so the certificate and the stone can always be matched, and it can be checked online on the IGI website at any time.\u003c\/p\u003e\u003cp\u003eKeep the report with the ring. It is the document your insurer and any future valuer will ask for, and it is independent confirmation of exactly what you bought.\u003c\/p\u003e\u003ch2\u003eChoosing your metal\u003c\/h2\u003e\u003cp\u003eThis ring is made to order in ten metals, so the version you choose is the version we build. There is no plating over a base metal and no filled or bonded gold anywhere in the range.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e925 sterling silver\u003c\/strong\u003e is the most affordable way to own the design. It is 92.5 percent pure silver, bright white, and it takes a high polish. Silver is softer than gold and it will pick up fine surface marks with daily wear, which most people come to like. It can also tarnish, and a soft polishing cloth brings it straight back.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e10K gold\u003c\/strong\u003e is 41.7 percent pure gold. It is the hardest and the most scratch resistant of the three gold alloys, which makes it a sensible choice for hands that work. The color is a little paler than 14K.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e14K gold\u003c\/strong\u003e is 58.5 percent pure gold and it is what most engagement rings sold in the United States are made from. It balances a warm, convincing color against real everyday durability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e18K gold\u003c\/strong\u003e is 75 percent pure gold. It has the deepest, richest color and the most weight in the hand. It is also the softest of the three, so it marks a little more readily.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eYellow gold is gold alloyed with silver and copper. Rose gold takes more copper, which gives the warm pink tone and also makes it the hardest of the three colors. White gold is alloyed with palladium or nickel and then finished with rhodium plating, which is what gives it that bright white face. Rhodium wears thin over time and wants redoing roughly every one to two years, which any jeweler can do quickly and cheaply. Every gold ring is stamped with its karat mark.\u003c\/p\u003e\u003ch2\u003eChoosing your carat size\u003c\/h2\u003e\u003cp\u003eThis ring is offered with a 2, 3, 4 or 5 carat center diamond. Carat is a unit of weight, 0.2 grams, and the size across the face grows more slowly than the weight, so a 4 carat princess is noticeably larger than a 2 carat but not twice as wide. The photographs may show a different carat size from the one you choose. The version you select is the one we make.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e2 carat\u003c\/strong\u003e is the most chosen size. It is unmistakably a statement diamond and still sits comfortably under a glove or a coat sleeve.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3 carat\u003c\/strong\u003e is a clear step up in presence and photographs beautifully. This is where most people land when they want the ring to be the first thing anyone notices.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4 carat\u003c\/strong\u003e covers the finger generously and suits longer fingers and larger ring sizes particularly well.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e5 carat\u003c\/strong\u003e is a red carpet diamond, the size people ask about across a room, and one that would be out of reach for most people as a mined stone.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eMade to order in our own workshop\u003c\/h2\u003e\u003cp\u003eMapple Gems is a family run jewelry workshop in Surat, in Gujarat, India. Surat is where roughly nine out of every ten diamonds in the world are cut and polished, and it is also one of the main centers of lab grown diamond production. We are not a dropshipper and we do not hold finished stock. When your order comes in, a goldsmith casts your metal in your size, a setter places every diamond by hand under a microscope, and the piece is polished, checked against the IGI report and photographed before it leaves us.\u003c\/p\u003e\u003cp\u003eMaking takes ten to fourteen working days for most orders. Shipping is free worldwide and fully insured, and it is normally three to seven working days once the ring has left the bench. Buying direct from the bench is the reason a ring like this costs what it does here rather than several times more on a high street.\u003c\/p\u003e\u003ch2\u003eCaring for your ring\u003c\/h2\u003e\u003cp\u003eDiamond attracts skin oil and hand cream, and a film of it on the underside of the stone is the single most common reason a ring looks dull. Soak the ring for ten minutes in warm water with a drop of mild dish soap, brush gently behind and underneath the stones with a soft toothbrush, rinse and pat dry with a lint free cloth. Once every two weeks is plenty.\u003c\/p\u003e\u003cp\u003eTake the ring off before the gym, gardening, swimming pools and hot tubs, and before using bleach or oven cleaner. Chlorine attacks the alloys in gold over time and it will do nothing good to sterling silver. Store it on its own, because diamond will scratch other jewelry. Have the claws checked by a jeweler once a year, which takes two minutes and is usually free. White gold will want its rhodium refreshed every one to two years.\u003c\/p\u003e\u003ch2\u003eQuestions people ask about this ring\u003c\/h2\u003e\u003ch3\u003eHow are the corners of the princess cut protected?\u003c\/h3\u003e\u003cp\u003eEach corner is held by a V shaped claw that wraps around the point. The corners are the most delicate part of a princess cut, so this is the most secure way to set it.\u003c\/p\u003e\u003ch3\u003eIs the halo square or rounded?\u003c\/h3\u003e\u003cp\u003eThe halo is square with sharp corners, matching the outline of the princess cut, so the whole head reads as one larger square.\u003c\/p\u003e\u003ch3\u003eWhat does the photo with three rings show?\u003c\/h3\u003e\u003cp\u003eIt shows this halo design worn on three fingers with different center sizes, so you can compare how the head looks as the carat weight goes up.\u003c\/p\u003e\u003ch3\u003eIs the band plain or set with diamonds?\u003c\/h3\u003e\u003cp\u003eThe band is plain polished metal. All the accent diamonds are in the square halo.\u003c\/p\u003e\u003ch3\u003eIs a lab grown diamond a real diamond?\u003c\/h3\u003e\u003cp\u003eYes. A lab grown diamond is chemically, physically and optically the same as a mined diamond: pure carbon, 10 on the Mohs scale, with the same brilliance and fire. The only difference is where it formed, which is why it is graded by the same laboratories on the same scales.\u003c\/p\u003e\u003ch3\u003eWhat color and clarity is the center diamond?\u003c\/h3\u003e\u003cp\u003eThe center diamond is E color and VVS2 clarity on every metal and every carat size. E is in the colorless range and VVS2 means no inclusion is visible to the eye, and very hard to find even under ten times magnification.\u003c\/p\u003e\u003ch3\u003eDoes the ring come with a certificate?\u003c\/h3\u003e\u003cp\u003eYes. The center diamond comes with an IGI grading report at no extra charge. It confirms the carat weight, color, clarity and cut, states that the diamond is lab grown, and matches the report number laser inscribed on the girdle.\u003c\/p\u003e\u003ch3\u003eWill a jeweler or a diamond tester say it is a diamond?\u003c\/h3\u003e\u003cp\u003eYes. A lab grown diamond tests as diamond on every standard tester because it is diamond. Telling lab grown from mined needs advanced laboratory equipment, and the IGI report already states the origin.\u003c\/p\u003e\u003ch3\u003eIs a lab grown diamond the same as moissanite?\u003c\/h3\u003e\u003cp\u003eNo. Moissanite is silicon carbide, a different gemstone with more rainbow fire and a lower hardness. This ring is set with lab grown diamond, which is carbon, grades on the diamond scale and tests as diamond.\u003c\/p\u003e\u003ch3\u003eWhat ring sizes can I order?\u003c\/h3\u003e\u003cp\u003eWe make sizes 1.5 to 13, including every half size. Choose your size at checkout. If you are unsure, measure a ring that already fits the correct finger, or ask a local jeweler to size you, and remember that fingers run slightly larger in hot weather and late in the day.\u003c\/p\u003e\u003ch3\u003eCan the ring be resized later?\u003c\/h3\u003e\u003cp\u003eIn most cases yes. Any jeweler can work on a plain section of shank. Resizing is harder where the band is set with stones all the way round, and moving more than about two sizes is better done by remaking the shank. Contact us first and we will tell you what is possible.\u003c\/p\u003e\u003ch3\u003eHow long will it take to arrive?\u003c\/h3\u003e\u003cp\u003eEvery ring is made to order in our workshop in Surat. Allow ten to fourteen working days for making, plus three to seven working days for free insured worldwide shipping. If you have a proposal date, tell us when you order and we will confirm whether we can meet it.\u003c\/p\u003e\u003ch3\u003eIs the metal solid, or is it plated?\u003c\/h3\u003e\u003cp\u003eIt is solid throughout. 925 sterling silver is 92.5 percent pure silver, and the gold options are solid 10K, 14K or 18K alloy stamped with the karat mark. Nothing in this range is gold plated, gold filled or gold bonded. White gold carries a standard rhodium finish.\u003c\/p\u003e\u003ch3\u003eDo you offer engraving?\u003c\/h3\u003e\u003cp\u003eYes, free of charge. Tell us the wording when you order and we will engrave the inside of the shank. Most people choose a date, initials or a short phrase of up to about twenty five characters.\u003c\/p\u003e\u003ch3\u003eWhat is your returns policy?\u003c\/h3\u003e\u003cp\u003eReturns are accepted within thirty days of delivery on an unworn ring in its original packaging, with the IGI report. Because every piece is made to order, engraved rings are handled case by case. Write to us and we will sort it out.\u003c\/p\u003e","brand":"Mapple Gems","offers":[{"title":"925 Sterling Silver \/ 2
