From above it is a plain rectangular solitaire. Turn the ring and a row of small diamonds appears in the collar beneath the stone, running right around the basket where nobody but the wearer usually sees it.\u003c\/p\u003e\u003ch2\u003eAt a glance\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCentre stone: Elongated radiant 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 radiant 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 a radiant is a rectangle with cropped corners, its hidden halo is rectangular too and follows those corners exactly. Seen from the side it reads as a bright frame floating under the stone. Seen from above it does not exist, so the radiant keeps its clean straight sided outline and nothing widens it.\u003c\/p\u003e\u003ch2\u003eWhy the band is kept so thin\u003c\/h2\u003e\u003cp\u003eAn elongated radiant already covers a lot of finger. Putting it on a narrow band removes anything that could compete, and with less metal beside it the stone reads larger still. At 4 and 5 carat the effect is considerable, because the shank nearly disappears and the diamond appears to sit unsupported.\u003c\/p\u003e\u003ch2\u003eWhat a radiant cut is\u003c\/h2\u003e\u003cp\u003eA radiant has the rectangular outline and cropped corners of an emerald cut, but it is faceted underneath like a brilliant. So you get the architectural shape of a step cut with the fire of a round. Cropped corners also mean no sharp points to chip, which is why radiants suit people who are hard on their rings.\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 over years of wear. 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 are set into the vertical wall of the basket one at a time under a microscope, before the radiant ever goes in. 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 properly, because it is the one place on this design where dirt collects out of sight. 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 a hidden halo make the ring sit higher?\u003c\/strong\u003e Slightly, yes. That extra height is what lets light under the stone. If you want the lowest possible profile, a plain basket suits you better.\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 band is straight and plain, so a slim straight band sits close beneath the halo.\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
