Three step cuts in a row, every edge parallel to the next.\u003c\/p\u003e\u003ch2\u003eAt a glance\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCentre stone: Emerald 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 band\u003c\/li\u003e\n\u003cli\u003eSide stones: Two emerald 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\u003eThree step cuts in a line\u003c\/h2\u003e\u003cp\u003eRepeating the same cut at three sizes gives the ring a strict geometry: the long facets of all three stones run in the same direction and flash together as the hand moves. It is the most formal arrangement in engagement rings, and the reason this design reads as architectural rather than romantic.\u003c\/p\u003e\u003ch2\u003eWhy matching is difficult\u003c\/h2\u003e\u003cp\u003eSide stones cut to a different ratio than the centre look wrong immediately, because a step cut has nothing to disguise it. Ours are cut to proportions that follow the centre stone, so the three read as one family rather than as a large stone flanked by whatever was available.\u003c\/p\u003e\u003ch2\u003eWhy the grade matters here\u003c\/h2\u003e\u003cp\u003eStep cuts have large open tables and a clear view straight into the stone. Three of them side by side make any difference in colour or clarity obvious, which is why all three are E colour and VVS2, matched as a set.\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. 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 three stones are set together so the tables finish level and the long edges stay parallel, which is the whole difficulty of a step cut three stone ring. 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 with stacking bands or worn alongside another ring. Those pieces are separate and are not included. The ring box shown is our standard packaging and comes with every order.\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. Large open tables show dust faster than brilliants do, so clean this ring weekly. Step cuts have open corners, so avoid knocking it against hard edges. 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 emerald cut. 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 stones sit above it, 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 tapered baguettes instead?\u003c\/strong\u003e Yes, we make that version too, and it gives a more art deco line.
