The trillions point outward from the centre stone, so the top of the ring widens into a shape rather than staying a straight row.\u003c\/p\u003e\u003ch2\u003eAt a glance\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCentre stone: 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: Three stone, radiant centre with a trillion on each side, pave shoulders\u003c\/li\u003e\n\u003cli\u003eAccent stones: Trillion and round 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 radiant cut\u003c\/h2\u003e\u003cp\u003eA radiant is a rectangle with cut corners, faceted underneath like a brilliant rather than in steps like an emerald cut. That combination is the whole point of it: the crisp outline of an emerald cut with the sparkle of a round. It was designed in 1977 specifically to give a rectangular stone the fire that step cuts do not have, and it remains the brightest of the rectangular shapes.\u003c\/p\u003e\u003ch2\u003eWhy trillions at the sides\u003c\/h2\u003e\u003cp\u003eA trillion is a triangular cut with a broad flat face. Set against the long side of a radiant, its straight edge sits flush to the centre stone and its point runs out toward the shoulder, which pulls the eye outward and makes the whole head look wider than it is. Trillions are also shallow, so they add width without adding height, and the ring keeps a low profile.\u003c\/p\u003e\u003ch2\u003eThe pave shoulders\u003c\/h2\u003e\u003cp\u003eBehind each trillion, small round diamonds continue down the shoulder in a shared claw setting, tapering as they go. They bridge the gap between the bold geometry at the top and the plain metal at the back of the band, so the ring does not stop abruptly.\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. 10K is the hardest alloy, 14K the everyday balance, 18K the richest colour. 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 trillions and the pave are matched to the same E and VVS2 grade. Trillions are shallow and show their colour readily, so matching them to the centre stone matters more than it would with a deeper cut.\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 trillions are cut to the length of your particular radiant so their straight edges meet it cleanly with no gap, and their three points are each set in a claw shaped to cover the tip. 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. Work into the two joins where the trillions meet the centre stone, which is the tightest space on the ring, then along the pave. 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 trillions and the pave 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 radiant. The two trillions and the pave are in addition.\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, close enough for most people. The trillions sit low and the shank is straight, so a plain or pave band sits neatly beside it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan it be resized?\u003c\/strong\u003e The pave stops part way round, leaving plain metal at the back. One or two sizes either way is straightforward.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAre trillion points fragile?\u003c\/strong\u003e They are the thinnest part of the stone, which is why each one is set inside a claw rather than left open. Set properly, a trillion wears as well as any other accent.\u003c\/p\u003e","brand":"Mapple Gems","offers":[{"title":"925 Sterling Silver \/ 2
