Step 1
Design & Selection
We finalise your design and hand-pick the certified center stone.
Save 20%A large heart shaped lab grown diamond takes the whole top of this ring, held by five pointed claws above a band lined with small round diamonds. It is a bold, romantic statement piece where the heart itself does almost all the talking.
The close front photograph shows the head clearly. Five teardrop tipped claws hold the heart: two on the upper lobes, two on the lower flanks and one at the point. The claws are shaped to a point, so they look neat against the large stone and keep a firm grip on the thin tip.
With a stone this size the band stays deliberately slim. A row of small round diamonds is set along each shoulder, and they appear tiny next to the heart, which makes the center look even larger. Past the midpoint of the shank the pave ends and the metal continues smooth.
The side view reveals a tall basket with a horizontal rail that ties the claws together. The pave row climbs right up beneath the rail, and the space under the stone is left open so light reaches the pavilion from the side.
Two photographs show the ring worn in rose gold against lilac and sage backgrounds, which give a real sense of how the heart spreads across the finger. The front shots in yellow, white and rose gold show the claw tips in each metal.
The heart cut is a modified brilliant with a cleft at the top and a point at the base, the hardest of the fancy shapes to cut well because both lobes must match exactly. It is one of the shapes we are asked for most often, and every heart we set is cut to excellent proportions and graded by IGI.
This is the same heart pave design as our other heart pave listings, shown here with a larger center stone, and its close photographs make all five claws easy to see. Our large heart solitaire on a plain dainty band is the alternative without side diamonds.
A 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.
Here is what that means for a ring you will wear every day:
It 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.
Every center diamond we set is graded E color and VVS2 clarity, 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.
The 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.
Keep 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.
This 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.
Yellow 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.
This 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 heart 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.
Mapple 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.
Making 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.
Diamond 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.
Take 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.
Yes, for most people. The basket keeps the stone secure and the slim band keeps weight down, although a large heart will naturally sit taller than a small one.
A heart has two lobes, two sides and a point. Five claws cover each of those areas, so the grip is balanced around the whole shape.
The rail links the claws partway down. It strengthens the head and stops the claws from spreading if the ring is knocked.
Yes. 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.
The 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.
Yes. 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.
Yes. 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.
No. 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.
We 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.
In 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.
Every 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.
It 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.
Yes, 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.
Returns 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.
