They sit in an open trellis gallery, where the claws cross over one another between the stones instead of meeting in solid walls. The band tapers away to nothing behind them.\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: Claw set round with a matching round diamond on each side, open trellis gallery\u003c\/li\u003e\n\u003cli\u003eAccent stones: 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\u003eThe most traditional three stone there is\u003c\/h2\u003e\u003cp\u003eRound centre, round sides, nothing else. It is the layout jewellers have been making longest, and the one people mean when they simply say a trilogy ring. If you want a three stone ring that will not look dated in twenty years, this is it.\u003c\/p\u003e\u003ch2\u003eThe trellis gallery\u003c\/h2\u003e\u003cp\u003eBetween each pair of stones the claws cross rather than sitting side by side. That leaves the gaps open, so light passes straight through the ring from underneath and all three diamonds stay lit. It also means less metal touching the stones, which keeps the cluster looking like diamonds rather than settings.\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. White gold is photographed here and is the usual choice for this design, because a colourless metal against E colour stones keeps everything reading white. 10K is the hardest alloy, 14K is the everyday balance, and 18K is the richest colour but the softest metal. 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.\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. A trellis gallery is built claw by claw rather than cast as one piece, which is why the openings between the stones are so clean. 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. Push the brush up through the open gallery from underneath, which is where the light gets in and where dirt blocks it. 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. The round side stones are matched to the same grade.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow big are the side stones?\u003c\/strong\u003e They are scaled to the centre so the proportions hold at every carat option. A 5 carat centre carries noticeably larger sides than a 2 carat one.\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 band tapers and the side stones sit just above it, so a straight band tucks in neatly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan it be resized?\u003c\/strong\u003e Yes. No stones are set in the shank.\u003c\/p\u003e","brand":"Mapple Gems","offers":[{"title":"925 Sterling Silver \/ 2
