There is no pave on the shank, no shoulder stones, nothing to read except the oval and a fine band. Turn the hand and the ring changes. A complete row of small round brilliants is set around the outside of the basket, sitting directly beneath the girdle of the centre stone, so the oval appears to float on a ring of light rather than on metal. That is the hidden halo, and its real purpose is optical rather than decorative. Because it sits below the girdle it never touches the outline of the centre stone, so the oval keeps its own crisp shape, but the reflected light from those small stones bounces up through the pavilion and makes the whole head look larger and brighter than a plain basket would. The second detail is at the base of the head, where the two ends of the shank do not simply meet the setting but pass over one another in a shallow crossover before running away as a single band. It gives the profile a soft twist and lifts the head just enough that a wedding band can tuck underneath without fouling the claws.\u003c\/p\u003e\u003ch3\u003eCenter stone details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eStone type: lab grown diamond\u003c\/li\u003e\n\u003cli\u003eShape: oval brilliant cut\u003c\/li\u003e\n\u003cli\u003eCarat weight: 2, 3, 4 or 5 carat, selected at checkout\u003c\/li\u003e\n\u003cli\u003eColor grade: E\u003c\/li\u003e\n\u003cli\u003eClarity grade: VVS2\u003c\/li\u003e\n\u003cli\u003eCut and polish: excellent\u003c\/li\u003e\n\u003cli\u003eSymmetry: excellent\u003c\/li\u003e\n\u003cli\u003eSetting: four claws, set north to south on a hidden halo basket\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eAccent stone details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eA continuous hidden halo of round brilliants set around the outside of the basket, below the girdle\u003c\/li\u003e\n\u003cli\u003eColor grade: E to F\u003c\/li\u003e\n\u003cli\u003eClarity grade: VS or better\u003c\/li\u003e\n\u003cli\u003eThe shank itself is left entirely plain\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eBand details\u003c\/h3\u003e\u003cp\u003eThe shank is round in section and polished bright.

It has the same carbon crystal structure, the same hardness of 10 on the Mohs scale and the same optical behaviour as a mined diamond, and it is graded on the same scales by the same laboratories.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the ring come with a certificate\u003c\/strong\u003e\u003cbr\u003eYes. An IGI certificate for the center stone is included at no extra charge.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is a hidden halo\u003c\/strong\u003e\u003cbr\u003eA ring of small diamonds set around the outside of the basket, below the girdle of the centre stone. It is invisible when you look straight down at the ring and shows only in profile.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes a hidden halo make the diamond look bigger\u003c\/strong\u003e\u003cbr\u003eIt makes the head look larger and brighter without changing the outline of the centre stone, because the small stones sit under the girdle rather than around it. A visible halo enlarges the outline but blurs the shape of the oval. A hidden halo keeps the shape crisp.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy does the shank cross over at the head\u003c\/strong\u003e\u003cbr\u003eThe crossover lifts the setting slightly and gives the profile a twist, and it opens a small gap beneath the head so a wedding band can sit close without pressing against the claws.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the hidden halo trap dirt\u003c\/strong\u003e\u003cbr\u003eAny close set stone needs occasional cleaning. Warm water, a drop of washing up liquid and a soft brush from underneath is enough, and we clean and repolish the ring free of charge for life.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this ring be resized\u003c\/strong\u003e\u003cbr\u003eYes, comfortably, because the shank carries no stones. The hidden halo sits in the head and is unaffected.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow long does the ring take to make\u003c\/strong\u003e\u003cbr\u003eEach ring is made to order and the halo is set by hand, so allow sixteen to twenty working days before dispatch.\u003c\/p\u003e\u003ch3\u003eWhy buy a lab grown diamond\u003c\/h3\u003e\u003cp\u003eA plain shank leaves the centre stone completely exposed, so its colour and clarity carry the whole ring. Lab grown material lets us set an E colour VVS2 oval of two to five carats where mined goods of the same grade would cost several times more, with a traceable origin and no mining.\u003c\/p\u003e\u003ch3\u003eOur services\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eIGI certificate for the center stone included at no extra cost\u003c\/li\u003e\n\u003cli\u003eMade to order in any size in our range\u003c\/li\u003e\n\u003cli\u003eFree resizing within the first year\u003c\/li\u003e\n\u003cli\u003eInsured worldwide shipping\u003c\/li\u003e\n\u003cli\u003eLifetime cleaning and polishing\u003c\/li\u003e\n\u003cli\u003eCustom design service for changes to any element of this ring\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eAbout Mapple Gems\u003c\/h3\u003e\u003cp\u003eMapple Gems is a jewellery workshop in Surat, India, the city where a large share of the world's diamonds are cut and polished.
