The band is plain and tapers towards the setting, which leaves the stones to do everything.\u003c\/p\u003e\u003ch2\u003eAt a glance\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCentre stone: Oval 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: Three stone, claw set, on a plain tapered band\u003c\/li\u003e\n\u003cli\u003eSide stones: Two half moon cut 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\u003eHalf moons, not trillions\u003c\/h2\u003e\u003cp\u003eThe usual three stone ring uses triangles or tapered baguettes at the sides. Half moons are harder to cut and harder to match, because the straight edge has to follow the curve of the centre stone exactly. Done properly, as here, the join between the three is almost closed and the eye reads a single wide oval rather than three separate diamonds.\u003c\/p\u003e\u003ch2\u003eThree stones, one line\u003c\/h2\u003e\u003cp\u003eEverything sits at the same height. There is no raised centre and no drop to the sides, so the top of the ring is a flat, wide surface that spans the finger. It is why a three stone of this kind looks larger on the hand than its carat weight suggests.\u003c\/p\u003e\u003ch2\u003eThe oval cut\u003c\/h2\u003e\u003cp\u003eA brilliant cut stretched into an ellipse. It carries the fire of a round while covering more of the finger, and the slight taper at each end lines up naturally with the flat edge of a half moon.\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, 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. The two half moons 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 half moons are cut to the centre stone rather than picked from stock, which is the only way to close the gaps between them, and all three are set together so the tops finish level. Allow two to three weeks for making, plus shipping.\u003c\/p\u003e\u003ch2\u003eAbout the photographs\u003c\/h2\u003e\u003cp\u003eSome of the lifestyle photographs show other rings worn alongside this one. Those are separate pieces and are not included.\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 and into the joins between them. 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 The centre oval and both half moons 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 oval. The half moons 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 tapered, so a straight band meets it cleanly on either side.\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 a different centre shape with half moon sides?\u003c\/strong\u003e Yes. Emerald, radiant and elongated cushion all work well between half moons.
