From above it is a single soft rectangle of light. Turn your hand and a bright row of small diamonds appears underneath, running right around the basket.\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 elongated cushion with a full hidden halo, 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\u003eHidden halo under a cushion\u003c\/h2\u003e\u003cp\u003eBecause a cushion has curved sides and rounded corners, its hidden halo curves with them rather than sitting in a straight line. That is harder to set than a halo under a round or an emerald cut, and it is why the underside of this ring looks considered rather than added. What the halo does is lift the stone clear of the finger so light reaches the pavilion from every direction, without touching the outline you see from above.\u003c\/p\u003e\u003ch2\u003eWhy elongated\u003c\/h2\u003e\u003cp\u003eA square cushion reads as a soft square. Stretch the outline and it becomes a long rounded rectangle instead, which lies along the finger and lengthens the hand. It also gives a larger face up size for the same carat weight, because less of the stone is buried in depth.\u003c\/p\u003e\u003ch2\u003eThe plain band\u003c\/h2\u003e\u003cp\u003eNo pave and no shaping. With a hidden halo already doing the decorative work underneath, a clean shank keeps the ring from reading as busy and makes it far easier to keep clean. It also means a wedding band sits close without fighting anything.\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, as photographed, throws the warmest contrast against a colourless stone. 10K is the hardest alloy, 14K is the everyday balance, and 18K is the richest colour but the softest metal. 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. Every halo stone goes into the vertical wall of the basket one at a time under a microscope, before the cushion 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, which 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\u003eCan you see the hidden halo when it is on?\u003c\/strong\u003e You will, because you look at your own hand from above and slightly to the side. Other people usually only notice it when you turn your hand.\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 a little, so a slim straight band sits close and a gently curved band sits perfectly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan it be resized?\u003c\/strong\u003e Yes, easily. No stones are set in the shank.\u003c\/p\u003e","brand":"Mapple Gems","offers":[{"title":"925 Sterling Silver \/ 2
