It gives the look of a solitaire worn with an eternity band, built as a single ring.\u003c\/p\u003e\u003ch2\u003eAt a glance\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCentre stone: Round 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 round on a split shank, one broad plain rail and one pave rail\u003c\/li\u003e\n\u003cli\u003eAccent stones: Round laboratory grown diamonds, 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\u003eTwo rails doing different jobs\u003c\/h2\u003e\u003cp\u003eThe upper rail is wide, flat and polished. It holds the diamond and gives the ring its structure. The lower rail is half its width and set end to end with small round diamonds. Because the two are so unalike, the eye reads them as a stacked pair rather than as a split band, which is exactly the intention.\u003c\/p\u003e\u003ch2\u003eWhy build it as one ring\u003c\/h2\u003e\u003cp\u003eA solitaire worn against a separate pave eternity band looks the same on day one. A year later the two have been rubbing: the softer band wears a groove, they spin out of alignment, and the pave loses stones where it meets the solitaire. Making the pair as one piece removes all of that. The gap stays even, nothing rubs, and the pave is set in a rail that is supported at both ends.\u003c\/p\u003e\u003ch2\u003eThe round brilliant\u003c\/h2\u003e\u003cp\u003eFifty seven facets arranged to return as much light as possible through the top of the stone. Raised on the broad rail and clear of the pave below, it has nothing competing with it at close range.\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. Yellow and white gold are photographed here. A popular version uses a yellow gold upper rail with a white metal pave rail, so the small stones read as bright as possible against a warm band. Tell us if you want it made that way. 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 pave diamonds are matched to the same E and VVS2 grade.\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. Both rails are cut from one piece of metal, the gap between them is filed and polished by hand, and the pave is set last so the small stones sit level along a rail that is already true. 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. Run the brush through the gap between the rails and along both sides of the pave. 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 pave is matched to the same grade.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the carat weight include the pave?\u003c\/strong\u003e No. The 2, 3, 4 and 5 carat options refer to the centre round brilliant. The pave rail 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 The ring already includes what most people would buy a band for. If you want a third ring, a plain slim band sits against the upper rail.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan it be resized?\u003c\/strong\u003e Yes, at the back where the rails rejoin, since the pave stops short of it. One or two sizes either way is straightforward.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I have the two rails in different metals?\u003c\/strong\u003e Yes. Tell us when you order and there is no extra charge.\u003c\/p\u003e","brand":"Mapple Gems","offers":[{"title":"925 Sterling Silver \/ 2
