From above it is a plain rectangular solitaire and nothing else. Turn your hand and a row of small diamonds appears in the collar beneath the stone, following the straight sides and the cropped corners exactly.\u003c\/p\u003e\u003ch2\u003eAt a glance\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCentre stone: Emerald 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 emerald cut with a full hidden halo, thin plain band\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\u003eA rectangular hidden halo\u003c\/h2\u003e\u003cp\u003eBecause an emerald cut is a rectangle with cropped corners, its hidden halo has to turn eight corners rather than follow a curve. Each one has to be square or the eye picks it up immediately from the side. Done properly it reads as a bright frame floating under the stone, while from above the emerald cut keeps its clean straight sided outline.\u003c\/p\u003e\u003ch2\u003eWhy clarity matters most here\u003c\/h2\u003e\u003cp\u003eAn emerald cut is a step cut. Long parallel facets and a wide open table give it those slow flashes of light, but they also mean the stone hides almost nothing. Any inclusion sits in plain view. This is exactly why every centre stone here is VVS2, a grade at which nothing is visible even under ten times magnification.\u003c\/p\u003e\u003ch2\u003eThe thin band\u003c\/h2\u003e\u003cp\u003eLess metal beside the stone makes the stone look bigger, because the eye has nothing to measure it against except the finger. At 4 and 5 carat the shank nearly disappears and the emerald cut appears to float on its halo.\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 makes a colourless stone read even whiter by contrast. On a band this narrow we would suggest 10K or 14K, which are harder alloys and hold a thin shank better. 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. The halo stones go into the vertical wall of the basket one at a time under a microscope, before the emerald cut is set. 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. Turn the ring over and brush the hidden halo, then wipe the table of the emerald cut, which shows fingerprints more than a brilliant does. 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 halo stones are matched to the same grade.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes an emerald cut sparkle less than a brilliant?\u003c\/strong\u003e Differently rather than less. You get long broad flashes instead of small rapid ones. The hidden halo adds a little brightness underneath without changing the character of the centre stone.\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 Very nearly. The halo lifts the centre slightly, so a slim straight band sits close beneath it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan it be resized?\u003c\/strong\u003e Yes, easily. There are no stones set anywhere in the shank.\u003c\/p\u003e","brand":"Mapple Gems","offers":[{"title":"925 Sterling Silver \/ 2
