In profile that ridge catches a single bright line of light that follows the finger, and it makes a fairly substantial band look far finer than it is. Approaching the head the shank does two things at once. It rises into cathedral shoulders, sweeping upward to carry the stone clear of the finger, and the knife edge parts into two blades that flare around a long open slot before closing again at the claws. Because the ridge splits rather than the flat of the band, each blade keeps its own edge and its own line of light, so the single highlight becomes two and then returns to one. Beneath the stone the gallery is left as an open cage with cross bars and nothing else: no halo, no under bezel, no accent stones anywhere on the ring.\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 flat strap claws on a raised open gallery\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eAccent stone details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eNo accent stones.

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 knife edge band\u003c\/strong\u003e\u003cbr\u003eA band whose outer surface rises to a ridge along its centre instead of being rounded or flat, so it presents a single bright line of light along the finger.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is a cathedral shoulder\u003c\/strong\u003e\u003cbr\u003eA shoulder that sweeps upward from the band to meet the setting, like the arch of a cathedral, lifting the stone clear of the finger.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes a knife edge wear down\u003c\/strong\u003e\u003cbr\u003eThe ridge softens very slightly over many years of wear, as any polished edge does. It is repolished during our lifetime service and returns to a crisp line.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is this different from your other oval split shank rings\u003c\/strong\u003e\u003cbr\u003eOthers pair the split with a hidden halo, a bezel, pavé vines, marquise bridges or split claws, and one uses a fine round wire with a narrow slit. This is the only one where a knife edge ridge splits into two blades over a cathedral rise, with no accents at all.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the cathedral rise make the ring sit high\u003c\/strong\u003e\u003cbr\u003eIt sits higher than a flush setting but lower than a raised solitaire crown. The rise is in the shoulders rather than under the stone, so the head itself stays close to the finger.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this ring be resized\u003c\/strong\u003e\u003cbr\u003eYes. The palm side is a solid knife edge band, which is where a sizing cut is made, well clear of the split section.\u003c\/p\u003e\u003ch3\u003eWhy buy a lab grown diamond\u003c\/h3\u003e\u003cp\u003eA ring with no accents anywhere puts all its weight on one stone, and an oval at two carats and above shows every characteristic it has. Lab grown material is what makes an E colour VVS2 oval at that size sensible in a setting built entirely from metalwork, in fully hallmarked gold, 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.
