It is the most traditional way to set a step cut, and the reason it has lasted is simple: the halo gives back the sparkle that a step cut does not produce on its own.\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: Rectangular halo around a four claw emerald cut, with a pave band\u003c\/li\u003e\n\u003cli\u003eAccent stones: Round 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\u003eWhat the halo does for a step cut\u003c\/h2\u003e\u003cp\u003eAn emerald cut works by reflection, not scintillation. Its long parallel facets return light in broad flashes, which is calm and architectural but never busy. Ringing it with small round brilliants puts a band of fast, fine sparkle directly against those still planes, and the contrast makes both read more strongly. The halo also makes the centre stone look noticeably larger, usually by close to half a carat of apparent size.\u003c\/p\u003e\u003ch2\u003eThe corners are kept square\u003c\/h2\u003e\u003cp\u003eA lazy halo rounds the corners and turns a rectangle into a soft blob. Here the halo is built with the corner stones angled so the frame keeps four true corners, echoing the cut corners of the emerald itself. It costs more time at the bench and it is the difference between a halo that flatters the stone and one that fights it.\u003c\/p\u003e\u003ch2\u003eWhy the grade is fixed at E and VVS2\u003c\/h2\u003e\u003cp\u003eOpen step cut facets hide nothing. Any tint of colour or any inclusion near the surface is visible straight through the table, in a way it would not be in a brilliant cut. That is why we do not offer a range on this ring. Every centre stone is E colour and VVS2 clarity, and the halo and pave stones are matched to it.\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. White gold is photographed here, and on a halo ring a colourless metal lets the frame disappear so it reads as diamond rather than metal. In yellow or rose gold the halo instead becomes a visible warm outline, which is a very different and equally good look. 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 halo and pave 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 halo is laid out around your particular centre stone, so the gap between frame and diamond is even on all four sides. Every accent is set by hand under a microscope. 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. A halo has a lot of small crevices, so brush around the outside of the frame and underneath it, then rinse well. 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 and pave stones are matched to the same grade.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the carat weight include the halo?\u003c\/strong\u003e No. The 2, 3, 4 and 5 carat options refer to the centre emerald cut stone. The halo and the pave are 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 the halo sits above the band line, so a straight wedding ring sits close on both sides.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan it be resized?\u003c\/strong\u003e The pave runs part way round and there is plain metal at the back. One or two sizes either way is straightforward.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo halo stones fall out?\u003c\/strong\u003e Not if they are set properly. Each accent sits in its own bead of metal raised from the frame, and we recommend a check every couple of years, the same as for any pave ring.\u003c\/p\u003e","brand":"Mapple
