From above, a clean oval outline on a diamond band.

It buys obvious size, but it also puts a ring of small diamonds between your eye and the outline of the centre stone, and once you have seen it you cannot unsee it. A hidden halo sits below the girdle on the outside of the basket, facing outward. The oval stays a clean, uninterrupted shape from above, and the extra light appears only in profile. If you want your stone to read as one large diamond rather than a cluster, this is the version to choose.\u003c\/p\u003e\u003ch2\u003eThe pave band\u003c\/h2\u003e\u003cp\u003eRound diamonds run down both shoulders in shared claws with almost no metal showing between them. The band tapers slightly as it travels, which makes the finger look longer and the centre stone look larger. The pave stops at the shoulders so there is plain metal at the back for sizing.\u003c\/p\u003e\u003ch2\u003eWhy an oval reads larger\u003c\/h2\u003e\u003cp\u003eAn oval brilliant carries most of its weight in spread rather than depth, so at a given carat weight it covers more finger than a round. A 2 carat oval measures roughly 9 by 6.5 millimetres, and a 5 carat closer to 13.5 by 9.5 millimetres. Against a narrow pave band that difference in scale is what gives the ring its proportion.\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. Rose gold and white gold are both photographed here. In white gold the pave disappears as metal and reads only as light; in rose or yellow gold the hidden halo shows as a sharper contrast under the stone. 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\u003eAbout the bow tie\u003c\/h2\u003e\u003cp\u003eEvery oval has the potential for a bow tie, a dark band across the centre caused by the proportions of the cut rather than by colour or clarity. No certificate grades it. We check each oval by eye and reject the ones that show it, since on a hidden halo design there is no top halo to distract from it.\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 hidden halo is built to the exact footprint of your individual oval, because a halo even half a millimetre too wide will peep out from above and defeat the whole purpose. 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. Brush upward into the basket, since the hidden halo is the part you will never notice getting dull, then work along both shoulders. 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 hidden halo make the stone look bigger?\u003c\/strong\u003e Not the way a visible halo does. It makes the head look lighter and lifts the stone visually, which reads as refinement rather than added size.\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 head is raised, so a straight band tucks under the hidden halo with only a small gap on most fingers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan it be resized?\u003c\/strong\u003e Within about one size. The pave runs down the shoulders and the back of the shank is left plain for this reason.\u003c\/p\u003e","brand":"Mapple Gems","offers":[{"title":"925 Sterling Silver \/ 2
