The side stones are kept deliberately small. They are there to frame the centre, not to share it.\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: Claw set emerald cut with a trillion on each shoulder, on a tapered band\u003c\/li\u003e\n\u003cli\u003eAccent stones: Trillion 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\u003eWhy small trillions\u003c\/h2\u003e\u003cp\u003eLarge side stones turn a three stone ring into a row, and the centre stops being the subject. These trillions are cut to roughly a fifth of the centre stone's width, so from any normal distance the ring reads as an emerald cut solitaire with two bright corners. Come closer and the structure appears.\u003c\/p\u003e\u003ch2\u003eTriangles against a rectangle\u003c\/h2\u003e\u003cp\u003eA trillion is a triangle with brilliant style faceting, so it throws fast, scattered light. An emerald cut is a step cut with long parallel facets that reflect in broad, mirror like planes. Putting a triangle beside a rectangle would look arbitrary if the two stones behaved the same way. Because they do not, each one explains the other.\u003c\/p\u003e\u003ch2\u003eThe tapered band\u003c\/h2\u003e\u003cp\u003eThe shank is at its widest where it meets the setting and narrows steadily as it travels round the finger. That taper does the same work as the small side stones: it funnels the eye inward and makes the centre stone look larger than a parallel sided band ever would.\u003c\/p\u003e\u003ch2\u003eWhy clarity matters on an emerald cut\u003c\/h2\u003e\u003cp\u003eAn emerald cut has a large open table and long step facets with nowhere for an inclusion to hide. It is the least forgiving shape in the trade. Our centre stones are VVS2, clean under ten times magnification, which is why we do not offer lower clarity grades on this cut.\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 gold is photographed here, and warm metal against a long colourless step cut is one of the oldest and best combinations in jewellery. White gold makes the same ring read cooler and more contemporary. 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 trillions 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 pair of trillions is cut to the width of your centre stone so the three sit as one unbroken line, and the taper of the band is set from your finger size. 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. Pay attention to the inner corner of each trillion, where the side stone meets the centre. 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. Both trillions are matched to the same grade.\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 trillions are in addition and are scaled to the centre.\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 Yes. The trillions sit low against the shoulders, so a plain straight band meets the ring with no gap.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan it be resized?\u003c\/strong\u003e Yes. The stones stop at the shoulders and the tapered section behind is plain metal.\u003c\/p\u003e","brand":"Mapple Gems","offers":[{"title":"925 Sterling Silver \/ 2
