A cushion is a square with heavily rounded corners and curved sides, and on a plain shank with nothing else on it the shape is the whole design.\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: Four claw solitaire on an open basket\u003c\/li\u003e\n\u003cli\u003eBand: Thin plain round band, no accent stones\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 softest of the square shapes\u003c\/h2\u003e\u003cp\u003eA cushion has no straight edges and no sharp corners. It reads as a rounded square, which is why the shape has been called a pillow cut, and it is the only square outline that does not look hard on a small hand. It is also the most forgiving square shape to wear, because there is no corner to chip.\u003c\/p\u003e\u003ch2\u003eLarge facets, broad fire\u003c\/h2\u003e\u003cp\u003eCushion cuts have fewer and larger facets than a modern round brilliant, and a deeper pavilion. That gives them broad flashes of colour rather than fine glitter, which is the same effect you see in the old mine cuts of the eighteen hundreds. It suits candlelight and low light better than a round does, and on a colourless E stone the fire reads white rather than tinted.\u003c\/p\u003e\u003ch2\u003eFour claws on the curve\u003c\/h2\u003e\u003cp\u003eThere is no flat edge for a claw to grip on a cushion, so each claw is shaped to the curve of the corner it sits on rather than bent over a straight line. They are filed low so the outline of the stone stays unbroken from above, and the basket is left open so light reaches the pavilion from below.\u003c\/p\u003e\u003ch2\u003eA band kept thin\u003c\/h2\u003e\u003cp\u003eThe shank is a plain round wire with nothing set into it. A cushion is a wide shape and thin metal lets it overhang the band slightly at the sides, which makes the stone read larger. It also sits flat against a wedding band with no gap.\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. This ring was photographed in white metal, and 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.\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. Cushions vary a great deal in how square or how elongated they are cut, so each head is built around the individual stone rather than pulled from a stock 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, brushing up into the open basket from underneath. A deep pavilion collects more underneath than a shallow stone, so clean it from the back. 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 is the diamond?\u003c\/strong\u003e E colour and VVS2 clarity, on every metal and every carat weight.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs a cushion cut as bright as a round?\u003c\/strong\u003e Not in the same way. Fewer, larger facets give broad flashes of fire rather than fine sparkle. Many people prefer it for exactly that reason.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSquare or elongated?\u003c\/strong\u003e We cut ours close to square, with a length to width ratio around 1.05 to 1.15, which is what most people mean when they ask for a cushion. Tell us if you want a more elongated stone and we will source 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?\u003c\/strong\u003e Yes. The band is thin and plain and the basket is narrow, so a straight band sits against it without a gap.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan it be resized?\u003c\/strong\u003e Yes. The shank is plain all the way around, so one or two sizes either way is straightforward.\u003c\/p\u003e","brand":"Mapple Gems","offers":[{"title":"925 Sterling Silver \/ 2
