Three soft cornered squares in a row make a deliberately old fashioned outline, closer to a ring inherited than one bought new.\u003c\/p\u003e\u003ch2\u003eAt a glance\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCentre stone: Cushion 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, cushion centre with two cushion side stones, each separately clawed\u003c\/li\u003e\n\u003cli\u003eAccent stones: Cushion 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\u003eThe cushion cut\u003c\/h2\u003e\u003cp\u003eA cushion is a square or slightly rectangular outline with rounded corners, faceted as a brilliant underneath. It was the standard diamond shape for most of the nineteenth century, when rings were made to be seen by candlelight, and it still gives a softer, warmer kind of sparkle than the precise flash of a modern round. Three of them in a row exaggerates that character rather than modernising it.\u003c\/p\u003e\u003ch2\u003ePast, present, future\u003c\/h2\u003e\u003cp\u003eThat is the meaning usually attached to three stones, one for each. It is why a ring like this turns up as often at an anniversary or a ring upgrade as at a proposal, and why the side stones here are substantial rather than shrunk down into accents.\u003c\/p\u003e\u003ch2\u003eWhy match the shapes\u003c\/h2\u003e\u003cp\u003eMany three stone rings use a contrasting cut at the sides, a trillion or a tapered baguette, to frame the centre. Using three cushions instead means all three stones sparkle the same way at the same moment, and the rounded corners of each one sit comfortably against the next, so the row reads as a single soft band of light across the finger.\u003c\/p\u003e\u003ch2\u003eThe band stays plain\u003c\/h2\u003e\u003cp\u003eThree cushions already fill the width of the finger. A polished shank with no pave keeps the design in the stones, makes the ring easy to clean, and leaves plenty of plain metal for resizing.\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 suits the antique character of a cushion better than almost any other combination. 10K is the hardest alloy, 14K the everyday balance, 18K the deepest 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. Both cushion side stones are matched to the same E and VVS2 grade, which matters a great deal when three stones of one shape sit side by side in the same light.\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 cushions are chosen together so they share one outline and one colour, and the heads are aligned so all three tables sit level. 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 gaps between the stones and underneath through the galleries. 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 side stones 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 cushion. The two side stones are in addition and are scaled to suit the centre you choose.\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 shank is straight and the three heads sit above the band line, so a plain or pave wedding ring sits close on either side.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan it be resized?\u003c\/strong\u003e Easily. There are no stones on the shank, so one or two sizes either way is straightforward.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the side stones be smaller?\u003c\/strong\u003e Yes. Tell us when you order, though the ring is designed around side stones that hold their own beside the centre.\u003c\/p\u003e","brand":"Mapple Gems","offers":[{"title":"925 Sterling Silver \/ 2
