The row fills the channel between the rails from one shoulder to the other.\u003c\/p\u003e\u003ch2\u003eAt a glance\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCentre stone: Elongated cushion 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: Five stone row held between two heavy gold rails\u003c\/li\u003e\n\u003cli\u003eSide stones: Four oval cut laboratory grown diamonds, graduated, 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\u003eA wide band with a row inside it\u003c\/h2\u003e\u003cp\u003eThe two rails are the structure of the ring, not decoration added to it. They run the full circumference and the five stones sit down in the channel between them, so the diamonds finish at about the height of the metal. What you get is a substantial gold band with a line of diamond set into it, rather than stones raised above a shank.\u003c\/p\u003e\u003ch2\u003eWhy ovals beside a cushion\u003c\/h2\u003e\u003cp\u003eRound side stones would leave gaps against a rectangular centre. Ovals, set with their length along the row, close against the cushion and against each other, so the five read as one continuous band of diamond. Graduating them twice on each side keeps the centre stone clearly the centre.\u003c\/p\u003e\u003ch2\u003eBuilt to be worn\u003c\/h2\u003e\u003cp\u003eNothing stands proud of the rails. The ring does not snag, does not rock on the finger and does not need taking off to pull on a glove. For a five stone ring carrying this much diamond, that is unusual, and it is the reason to choose this construction over a conventional raised setting.\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. This ring was photographed in yellow gold, which suits the weight of the rails, but every metal is made to order and priced above. A popular version uses yellow rails with white metal settings around the stones, as shown in the photographs; tell us if you would like it made that way. 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. All four oval side stones are matched to the same E and VVS2 grade.\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 rails are formed from one piece, the channel is cut to each of the five stones so they sit at matching depths, and the ovals are set in sequence so the graduation stays even. 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, running the brush along both channels and between the stones. A low set row collects soap rather than losing it. 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 are the diamonds?\u003c\/strong\u003e All five stones are E colour and VVS2 clarity, on every metal and every carat weight.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the carat weight include the side stones?\u003c\/strong\u003e No. The 2, 3, 4 and 5 carat options refer to the centre cushion. The four ovals are in addition and are scaled to suit it.\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?\u003c\/strong\u003e Yes. The rails are straight and level all the way round, so a plain band meets the ring with no gap.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan it be resized?\u003c\/strong\u003e Within a size either way. A heavy double rail band is more work to resize than a thin shank, so please order your correct size and ask us for a free sizer.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I have this with round side stones instead?\u003c\/strong\u003e Yes, though ovals close the gaps better against a rectangular centre. We will show you both before making.\u003c\/p\u003e","brand":"Mapple Gems","offers":[{"title":"925 Sterling Silver \/ 2
