Everything that could compete with the stone has been taken away, and the only ornament is the one you cannot see from above.\u003c\/p\u003e\u003ch2\u003eAt a glance\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCentre stone: Elongated 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 with a hidden halo under the basket, on a thin plain shank\u003c\/li\u003e\n\u003cli\u003eAccent stones: Round laboratory grown diamonds in the hidden halo, 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\u003eWhy the band is this thin\u003c\/h2\u003e\u003cp\u003eA narrow shank makes the centre stone look larger, for the simple reason that the eye judges size by comparison. On a 2 millimetre band a 3 carat cushion reads as enormous. The trade is that a thin band flexes more over years of wear, which is why we make this one in a heavier gauge than it looks and do not recommend it in silver for someone who works with their hands all day.\u003c\/p\u003e\u003ch2\u003eWhat the hidden halo adds\u003c\/h2\u003e\u003cp\u003eThe halo sits in the gallery beneath the girdle, facing outward rather than upward. It does not widen the outline of the stone, so the cushion keeps its own soft shape. What it does is fill the shadow under the basket with light, so from the side the diamond looks lifted rather than seated, and from above the stone appears to sit on nothing at all.\u003c\/p\u003e\u003ch2\u003eThe elongated cushion\u003c\/h2\u003e\u003cp\u003eA cushion is a square or rectangular cut with rounded corners, faceted as a brilliant underneath. The elongated version stretches that outline so it runs along the finger, which flatters the hand the way an oval does but keeps the softer, more antique edges. Cushions were the standard diamond shape for most of the nineteenth century, and the modern version still has some of that candlelit, less clinical character.\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 a thin warm band against a colourless stone is the whole point of this design. For a band this narrow, 10K and 14K hold their shape better over time than 18K. 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 hidden halo diamonds are matched to the same E and VVS2 grade.\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 hidden halo is set from underneath before the centre stone goes in, and the claws are drawn down to the cushion by hand so they follow its rounded corners rather than sitting square on them. 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. Brush up into the gallery from below, because the hidden halo is where dust settles and it is the one part you will not notice going dull. 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 hidden halo stones are matched to the same grade.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the carat weight include the hidden halo?\u003c\/strong\u003e No. The 2, 3, 4 and 5 carat options refer to the centre cushion. The halo is 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. The shank is straight and thin, so a matching narrow band sits neatly beside it with no gap.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan it be resized?\u003c\/strong\u003e Yes, easily, since the whole band is plain metal. One or two sizes either way is straightforward.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs a thin band strong enough for a large stone?\u003c\/strong\u003e Yes, when it is made properly. We use a thicker gauge than the width suggests and the setting itself braces the top of the ring. For daily wear with a 4 or 5 carat stone we would steer you toward 10K or 14K rather than silver.\u003c\/p\u003e","brand":"Mapple Gems","offers":[{"title":"925 Sterling Silver \/ 2
