The shank runs as one thin line around the finger, then splits into a narrow V at the front and lifts the stone between its two arms. From above it is a plain solitaire. From the side it is something else entirely.\u003c\/p\u003e\u003ch2\u003eAt a glance\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCentre stone: Marquise 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: Claw set marquise on a split shank with an open V beneath the stone\u003c\/li\u003e\n\u003cli\u003eAccent stones: None, this is a true solitaire\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\u003eWhat the split does\u003c\/h2\u003e\u003cp\u003eWhere a normal shank meets the setting in a single solid block of metal, this one divides and opens. Two things follow. The stone appears to sit higher and freer, because there is daylight under it rather than gold. And the gap draws the eye upward along the two arms to the point of the marquise, which lengthens the whole ring.\u003c\/p\u003e\u003ch2\u003eWhy it suits a marquise\u003c\/h2\u003e\u003cp\u003eA marquise is the longest of the common outlines. The V of the split shank repeats the V of the stone's lower point, so the setting and the stone share a shape instead of arguing with each other. On a rounder stone the same split would look unrelated to what sits above it.\u003c\/p\u003e\u003ch2\u003eThin, but engineered\u003c\/h2\u003e\u003cp\u003eThe band is deliberately slim, which makes the centre stone read larger. Where it splits, the two arms are thickened slightly on the inside face where it does not show, so the fork carries the weight of a 5 carat stone without flexing. Both points of the marquise are protected by a v claw.\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 is photographed here, and the polished split catches light in two separate lines on either side of the stone. For a thin split shank we would suggest 10K or 14K, which are the harder alloys. 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. The angle of the split is set from the actual length of your centre stone, so a longer marquise gets a longer, shallower V and a shorter one gets a tighter fork. 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. Run the brush through the open V, which is the one place on this ring where anything can lodge. 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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs a split shank weaker than a solid one?\u003c\/strong\u003e Not as we build it. The two arms are reinforced on the inner face and rejoin into a full shank behind the setting.\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 Yes, very well. The split is at the front and the band meets an ordinary round shank at the sides, so a straight band sits flat.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan it be resized?\u003c\/strong\u003e Yes. There are no stones in the shank, so it resizes like any plain band.\u003c\/p\u003e","brand":"Mapple Gems","offers":[{"title":"925 Sterling Silver \/ 2
