The band is flat and square edged, and it runs straight into the setting without tapering, so the whole ring is built from straight lines.\u003c\/p\u003e\u003ch2\u003eAt a glance\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCentre stone: Asscher 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: Bar set centre with two trillion side stones, on a flat band\u003c\/li\u003e\n\u003cli\u003eSide stones: Two trillion 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\u003eBars instead of claws\u003c\/h2\u003e\u003cp\u003eThe asscher is gripped along two opposite edges by flat bars of metal rather than by four claws at the corners. Nothing sits on top of the stone, so the table stays completely open, and the two bars line up with the straight edges of the cut instead of interrupting them. It is a cleaner solution than claws on a square stone, and a stronger one.\u003c\/p\u003e\u003ch2\u003eTrillions that point inward\u003c\/h2\u003e\u003cp\u003eEach side stone is a triangle set with its point towards the centre and its long edge against the band. That direction matters: turned the other way the ring would look wider than the finger, whereas this way the eye runs inward to the asscher.\u003c\/p\u003e\u003ch2\u003eThe asscher cut\u003c\/h2\u003e\u003cp\u003eA step cut square with cropped corners and deep parallel facets that draw the eye down into the stone, the effect often called a hall of mirrors. There is no brilliant faceting to hide behind, which is why we set only E colour, VVS2 stones in this design.\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. All three golds are photographed here. Yellow gold makes the bars read strongly against the stone; white gold lets them disappear and the three diamonds run together. 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 two trillions 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 bars are cut and fitted to the measured stone so the asscher sits square between them, and the trillions are set level with it rather than dropped below. 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 under the centre stone between the two bars. There is very little for anything to collect in on this setting. The points of a trillion are its weak spots, so avoid knocks. 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 are the diamonds?\u003c\/strong\u003e The centre asscher and both trillions are E colour and VVS2 clarity, on every metal and every carat weight. On step cuts you see straight into the stone, so this matters more than usual.\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 asscher. The trillions are in addition and are scaled to suit it.\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\u003eIs a bar setting secure?\u003c\/strong\u003e Yes, and on a square stone it is more secure than corner claws, since the metal runs the full length of two edges rather than gripping four points.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill a wedding band sit flush?\u003c\/strong\u003e Yes. The band is flat and straight, and the stones sit above it, so a straight band meets it cleanly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan it be resized?\u003c\/strong\u003e Yes, at the back. One or two sizes either way is straightforward.\u003c\/p\u003e","brand":"Mapple Gems","offers":[{"title":"925 Sterling Silver \/ 2
