It rises to a ridge along the centre line of the finger and falls away to a face on each side, and that geometry is what makes it the hardest band to engrave well. On a flat band the graver runs across one plane. Here it has to work two planes that meet at an angle, and the scroll on each face has to resolve into the ridge without the pattern breaking where the two sides meet. Done properly the ridge reads as a bright line of unengraved gold running the whole way round with dense carved ornament falling away below it on both sides, which is why a knife edge catches light so much harder than a round band. Every edge on the ring is then milgrained, the two outer edges of the shank, both sides of the ridge and the collar around the stone, so the whole piece is bounded by fine beading rather than by cut lines. The head itself sits on a low milgrained collar with four plain claws, and it is kept deliberately simple, because a decorated head on top of this much shank ornament would leave the eye nowhere to settle.\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 on a milgrain edged collar, set north to south\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eAccent stone details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eThis design carries no 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 shank cut to a triangular section so it rises to a ridge along the centre of the finger and slopes away on both sides. It catches light far harder than a round or flat band because the ridge presents a continuous bright line.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy is engraving a knife edge harder\u003c\/strong\u003e\u003cbr\u003eBecause the graver has to work two sloping planes that meet at an angle, and the scroll on each face must resolve into the ridge without the pattern breaking where the sides meet.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is this different from your other engraved rings\u003c\/strong\u003e\u003cbr\u003eOur cathedral engraved ring uses a flat faced shank, and our filigree ring uses a wide flat band. This one is engraved on the two sloping faces of a knife edge, which is the most demanding of the three to cut.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the engraving wear away\u003c\/strong\u003e\u003cbr\u003eSlowly, and mainly on the palm side. We recut and sharpen it during servicing whenever you want it refreshed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this ring be resized\u003c\/strong\u003e\u003cbr\u003eWithin about one size. Larger changes break the continuity of the scroll and the ridge, so we prefer to remake the shank and re-engrave it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow long does the ring take to make\u003c\/strong\u003e\u003cbr\u003eTwo engraved faces plus milgrain on six separate edges, all cut by hand, so allow twenty two to twenty six working days before dispatch.\u003c\/p\u003e\u003ch3\u003eWhy buy a lab grown diamond\u003c\/h3\u003e\u003cp\u003eThis is a ring priced largely in bench hours, and lab grown material means paying for that engraving does not force a smaller or lower graded centre stone. An E colour VVS2 oval of two to five carats sits above the scrollwork, 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.
