A classic three stone, made plainly, with nothing on the shoulders and nothing under the setting.\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: Three stone, claw set, on a plain band\u003c\/li\u003e\n\u003cli\u003eSide stones: Two round brilliant 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\u003eThree rounds, the original arrangement\u003c\/h2\u003e\u003cp\u003eBefore shaped side stones became common, this was what a three stone ring meant: one larger round between two smaller ones, evenly spaced, level across the top. It is the version that has aged best, because there is nothing in it to date.\u003c\/p\u003e\u003ch2\u003ePast, present and future\u003c\/h2\u003e\u003cp\u003eThe meaning usually given to three stones is Victorian rather than ancient, but it has stuck, and it is the reason this arrangement remains the most common alternative to a solitaire for an engagement.\u003c\/p\u003e\u003ch2\u003eWhy the side stones matter\u003c\/h2\u003e\u003cp\u003eThey are large enough to be judged by eye, so a difference in colour or cut quality between them and the centre would be obvious. All three are selected together at the same E colour and VVS2 clarity.\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 both yellow gold and white metal, and 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. Both side stones 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. The side stones are cut to proportions that suit the centre, and all three are set together so the tops finish level and the spacing stays even. Allow two to three weeks for making, plus shipping.\u003c\/p\u003e\u003ch2\u003eAbout the photographs\u003c\/h2\u003e\u003cp\u003eSome photographs show this ring worn with a curved diamond set band nested against it. That band is a separate piece and is not included. We make one shaped to follow this ring, so ask us if you would like the pair.\u003c\/p\u003e\u003ch2\u003eLooking after it\u003c\/h2\u003e\u003cp\u003eWarm water, mild washing up liquid and a soft toothbrush, brushing behind all three stones. 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 are the diamonds?\u003c\/strong\u003e All three stones are E colour and VVS2 clarity, on every metal and every carat weight.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the carat weight include the side stones?\u003c\/strong\u003e No. The 2, 3, 4 and 5 carat options refer to the centre round. The two side stones are in addition and are scaled to suit it.\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?\u003c\/strong\u003e Yes. The band is plain, and the curved band shown in the photographs nests against it closely if you want a closer fit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan it be resized?\u003c\/strong\u003e Yes, at the back. One or two sizes either way is straightforward.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I have larger side stones?\u003c\/strong\u003e Yes. Tell us the proportions you want; three stones closer in size makes a considerably bolder ring.\u003c\/p\u003e","brand":"Mapple Gems","offers":[{"title":"925 Sterling Silver \/ 2
