Brilliant cutting in the centre, step cutting at the sides. Two different kinds of light in one ring, which is why this combination has outlasted nearly every other three stone arrangement.\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 centre with channel held tapered baguettes on both shoulders\u003c\/li\u003e\n\u003cli\u003eAccent stones: Tapered baguette laboratory grown diamonds, E colour, VVS2\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\u003eBrilliant against step\u003c\/h2\u003e\u003cp\u003eA marquise is a brilliant cut, covered in triangular and kite shaped facets that scatter light into flashes. A baguette is a step cut, with long parallel facets that behave like a mirror and give broad, calm reflections instead. Set next to each other, each one makes the other more obvious. The centre stone sparkles harder because the sides do not compete with it.\u003c\/p\u003e\u003ch2\u003eWhy tapered, not straight\u003c\/h2\u003e\u003cp\u003eA tapered baguette is wider at the end nearest the centre stone and narrows as it runs down the shoulder. That taper does two jobs. It visually pushes the eye towards the centre, and it lets the side stones sit flush against the widest part of the marquise without a wedge of metal filling the gap.\u003c\/p\u003e\u003ch2\u003eA shape from the deco period\u003c\/h2\u003e\u003cp\u003eMarquise centres with baguette shoulders were made in quantity in the 1920s and 1930s, when step cuts and strong geometry were in fashion. This ring keeps that structure but sets it on a plain modern shank rather than a pierced or engraved gallery, so it reads clean rather than antique.\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. White gold is photographed here, which is the traditional choice for this design because the colourless metal lets the three stones read as one continuous line. Yellow and rose gold separate them more. 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 baguettes are matched to the same E and VVS2 grade, which matters more on a step cut than on any other shape.\u003c\/p\u003e\u003ch2\u003eWhy clarity matters on a baguette\u003c\/h2\u003e\u003cp\u003eStep cut facets are large and open, so there is nowhere for an inclusion to hide. A VVS2 baguette stays clean to the eye. This is the main reason we do not offer lower clarity grades on this design.\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 pair of baguettes is cut to match the width of your centre stone, so the three stones form one unbroken line rather than a centre with two afterthoughts. 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 along the channel at both ends of each baguette. 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. Both baguettes are matched to the same grade.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the carat weight include the baguettes?\u003c\/strong\u003e No. The 2, 3, 4 and 5 carat options refer to the centre marquise. The side stones are in addition and are scaled to the centre.\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. The baguettes sit low and flat along the shoulders, so a straight band meets the ring cleanly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan it be resized?\u003c\/strong\u003e Yes, within a size or two. The baguettes stop at the shoulders and the back of the shank is plain.\u003c\/p\u003e","brand":"Mapple Gems","offers":[{"title":"925 Sterling Silver \/ 2
