Seen from the end the shank looks ribbed, almost like a length of cord, which is unusual under a stone this size.\u003c\/p\u003e\u003ch2\u003eAt a glance\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCentre stone: Elongated antique cushion cut 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 claws on a multi rail ribbed shank\u003c\/li\u003e\n\u003cli\u003eAccent stones: None\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\u003eA shank made of rails\u003c\/h2\u003e\u003cp\u003eInstead of one solid band, the shank is formed from several slim rails held together. They stay parallel around the finger and then separate slightly under the stone, so the claws appear to grow out of the band rather than being fixed on top of it. It gives a large diamond a much lighter base than a plain heavy shank would.\u003c\/p\u003e\u003ch2\u003eThe antique cushion\u003c\/h2\u003e\u003cp\u003eA cushion cut is a square or rectangle with rounded sides and corners. The antique version keeps the larger, fewer facets and the open culet of the old mine cuts, which gives broad flashes of light rather than the fine glitter of a modern brilliant. Elongated, as this one is, it covers more of the finger and reads slimmer than a square cushion of the same weight.\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. This ring was photographed in yellow gold, which suits the antique cut and shows the ribbing on the shank most clearly, but every metal is made to order and priced above. 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.\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 rails are shaped and soldered one against the next, then filed and polished as a single piece so the grooves between them stay even the whole way round. The claws are fitted last to the measured stone. 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 along the grooves between the rails, which hold more soap than a flat band does, and behind the stone where the claws meet. 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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs an antique cushion less brilliant than a modern cut?\u003c\/strong\u003e It sparkles differently rather than less. Bigger facets give slower, broader flashes, which is what people mean when they call these cuts warm or candlelit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the certificate really free?\u003c\/strong\u003e Yes. The IGI report is included in the price on every variant.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill a wedding band sit flush?\u003c\/strong\u003e Against the ribbed shank a straight band meets the high points of the rails. A band with a slight curve, or one of our shaped bands, sits closer. Ask us and we will make one to match.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan it be resized?\u003c\/strong\u003e Yes, but the rails have to be cut and rejoined together, so we would rather make it to your size. One or two sizes of adjustment is still straightforward afterwards.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I have it in a square cushion instead of elongated?\u003c\/strong\u003e Yes, at the same price. Tell us when you order.\u003c\/p\u003e","brand":"Mapple Gems","offers":[{"title":"925 Sterling Silver \/ 2
