The trapezoids taper away from the centre so the three stones read as one continuous band of light across the finger, and the shank stays plain and rounded behind them.\u003c\/p\u003e\u003ch2\u003eAt a glance\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCentre stone: Elongated radiant 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: Four double claw centre with claw set trapezoid sides\u003c\/li\u003e\n\u003cli\u003eSide stones: Step cut trapezoid laboratory grown diamonds, E colour, VVS2\u003c\/li\u003e\n\u003cli\u003eBand: Plain, rounded\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 trapezoids and not trillions\u003c\/h2\u003e\u003cp\u003eA trillion side stone is triangular and points away from the centre, which breaks the line of the ring. A trapezoid has a long edge that sits flat against the girdle of the radiant and a shorter edge at the outside, so it fills the space beside the centre stone completely and carries the eye outward instead of stopping it. On a rectangular centre like a radiant, that flat contact edge is the whole point.\u003c\/p\u003e\u003ch2\u003eStep cut beside brilliant cut\u003c\/h2\u003e\u003cp\u003eThe radiant is a hybrid, cut with brilliant style facets inside a rectangular outline, so it throws the short bright flashes of a round. The trapezoids are step cut, with long parallel facets that give broad calm planes of light. Putting the two together stops the ring from looking like three versions of the same thing, and the quieter sides make the centre stone look livelier by contrast.\u003c\/p\u003e\u003ch2\u003eHow three stones wear\u003c\/h2\u003e\u003cp\u003eThree stone rings sit wider on the finger than a solitaire of the same centre weight and use more total carat, so the ring reads substantial from across a room. The trade off is height and width at the head, which is why the shank is kept plain here rather than adding pave to an already busy top.\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. 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 trapezoid sides are matched to the same E and VVS2 grade, which is essential on a three stone ring where the side stones are large enough to be judged alongside the centre rather than read as accents.\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. Each pair of trapezoids is cut to the measurements of the individual centre stone so the contact edges meet the radiant with no gap, which is why this design cannot be made from stock parts. 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. Step cut stones show dirt more readily than brilliants because their flat facets have nowhere to hide it, so clean the trapezoids as often as the centre. Take the ring 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 radiant and both trapezoid sides are E colour and VVS2 clarity, on all metals and all carat weights.\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 radiant. The trapezoids are in addition and are scaled to the centre stone.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow wide does this sit on the finger?\u003c\/strong\u003e Noticeably wider than a solitaire. A 3 carat centre with matched trapezoids covers roughly the width of the finger between the knuckles.\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 trapezoids sit low against the shank, so a straight band meets it cleanly on both sides.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan it be resized?\u003c\/strong\u003e Yes, at the back where the band is plain. One or two sizes either way is straightforward.\u003c\/p\u003e","brand":"Mapple Gems","offers":[{"title":"925 Sterling Silver \/ 2
