The band is plain and narrow from front to back. Nothing else is added, because nothing else is needed.\u003c\/p\u003e\u003ch2\u003eAt a glance\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCentre stone: Oval brilliant laboratory grown diamond\u003c\/li\u003e\n\u003cli\u003eCarat options: 2, 3, 4 and 5 carat\u003c\/li\u003e\n\u003cli\u003eColour and clarity: E colour, VVS2 clarity\u003c\/li\u003e\n\u003cli\u003eCertificate: IGI, included free\u003c\/li\u003e\n\u003cli\u003eSetting: Four claw oval with a hidden halo under the basket, on a thin plain shank\u003c\/li\u003e\n\u003cli\u003eAccent stones: Round laboratory grown diamonds in the hidden halo, E colour, VVS2\u003c\/li\u003e\n\u003cli\u003eMetals: 925 silver, 10K, 14K and 18K gold in yellow, rose and white\u003c\/li\u003e\n\u003cli\u003eMade: To order in Surat, India\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eThe most requested engagement ring shape there is\u003c\/h2\u003e\u003cp\u003eThe oval solitaire on a plain band has been the single most searched for engagement ring style for several years running, and the reason is not fashion. An oval spreads its weight along the finger rather than down into the stone, so at the same carat weight it covers more of the hand than a round brilliant and lengthens the finger while it does it. A 2 carat oval here measures roughly 9 by 6.5 millimetres, and a 5 carat closer to 13.5 by 9.5 millimetres.\u003c\/p\u003e\u003ch2\u003eWhat the hidden halo changes\u003c\/h2\u003e\u003cp\u003eThe halo sits in the gallery, below the girdle, facing outward instead of upward. It adds no width to the outline, so from above this is still a clean oval solitaire. From the side, the shadow under the basket becomes a bright line and the stone reads as floating. It is the one piece of decoration on this ring and it is deliberately the piece nobody else notices.\u003c\/p\u003e\u003ch2\u003eWhy a plain band\u003c\/h2\u003e\u003cp\u003ePave shoulders make a band look wider and a centre stone look smaller. Leaving the shank plain does the opposite: the narrow polished metal gives the eye nothing to measure against except the diamond. It is also the most practical choice, since a plain band can be resized freely, never needs stones checked, and will not wear a groove into a wedding ring sitting next to it.\u003c\/p\u003e\u003ch2\u003eWhat laboratory grown means here\u003c\/h2\u003e\u003cp\u003eA laboratory grown diamond is a diamond. It is crystallised carbon with the same cubic structure, the same 10 on the Mohs scale, the same refractive index of 2.42 and the same dispersion as a mined stone. Ours are grown by chemical vapour deposition and high pressure high temperature methods, then cut and polished by hand. This is not moissanite, not cubic zirconia and not a simulant. A gemmologist testing it will read diamond, because it is diamond.\u003c\/p\u003e\u003ch2\u003eMetals\u003c\/h2\u003e\u003cp\u003eChoose 925 sterling silver, or 10K, 14K or 18K gold in yellow, rose or white. Rose gold is photographed here, and a warm thin band against a colourless oval is one of the most popular combinations we make. 10K is the hardest alloy, 14K the everyday balance, 18K the richest colour but the softest metal. White gold is rhodium plated and will want replating every one to two years.\u003c\/p\u003e\u003ch2\u003eEvery centre stone arrives IGI certified\u003c\/h2\u003e\u003cp\u003eThe centre diamond is graded by IGI, the International Gemological Institute, and the certificate comes with the ring at no extra charge. It states the carat weight, the E colour grade, the VVS2 clarity grade, the measurements and the girdle inscription, and confirms in writing that the stone is laboratory grown. The hidden halo diamonds are matched to the same E and VVS2 grade.\u003c\/p\u003e\u003ch2\u003eAbout the bow tie\u003c\/h2\u003e\u003cp\u003eEvery oval can show a bow tie, a dark band across the middle of the stone caused by the proportions of the cut rather than by colour or clarity. No certificate grades it, and on a plain solitaire there is no pave to distract from it. We check every oval by eye and reject the ones that show it.\u003c\/p\u003e\u003ch2\u003eMade to order in our own workshop\u003c\/h2\u003e\u003cp\u003eMapple Gems is a family run workshop in Surat, India, where most of the world's diamonds are cut and polished. The hidden halo is set from underneath before the centre stone goes in, and the four claws are drawn down onto the oval by hand so they sit at even points around the curve. Allow two to three weeks for making, plus shipping.\u003c\/p\u003e\u003ch2\u003eLooking after it\u003c\/h2\u003e\u003cp\u003eWarm water, mild washing up liquid and a soft toothbrush. Brush up into the gallery from below, because the hidden halo collects what the rest of the ring does not. Take it off for the gym, gardening and swimming.\u003c\/p\u003e\u003ch2\u003eQuestions we are asked\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eWhat colour and clarity is the diamond?\u003c\/strong\u003e Every centre stone is E colour and VVS2 clarity, on every metal and every carat weight. The hidden halo stones are matched to the same grade.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the carat weight include the hidden halo?\u003c\/strong\u003e No. The 2, 3, 4 and 5 carat options refer to the centre oval. The halo is in addition.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the certificate really free?\u003c\/strong\u003e Yes. The IGI report for the centre stone is included in the price on every variant.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill a wedding band sit flush against it?\u003c\/strong\u003e Yes. The shank is straight and narrow, so a matching plain band sits neatly beside it with no gap on either side.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan it be resized?\u003c\/strong\u003e Yes, freely. The whole band is plain metal, which makes this one of the easiest rings we make to resize.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I see the hidden halo when I am wearing it?\u003c\/strong\u003e You catch it when you turn your hand, and other people mostly do not. That is the appeal.\u003c\/p\u003e","brand":"Mapple Gems","offers":[{"title":"925 Sterling Silver \/ 2
