The cut has a small table and a high crown, so it flashes in a few large pulses of light rather than the fine even glitter of a modern brilliant.\u003c\/p\u003e\u003ch2\u003eAt a glance\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCentre stone: Antique round 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: Low scalloped head with a pierced decorative gallery, on a thin plain shank\u003c\/li\u003e\n\u003cli\u003eAccent stones: None, the centre stone stands alone\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\u003eThe old European cut\u003c\/h2\u003e\u003cp\u003eBefore Tolkowsky published his calculations in 1919, round diamonds were cut by eye for candlelight. The result had a small table, a tall crown, a deep pavilion and a visible open culet at the bottom. Those proportions send light back in fewer, bigger flashes, with far more coloured fire than a modern brilliant. It is a quieter stone in bright daylight and a considerably more interesting one in a restaurant.\u003c\/p\u003e\u003ch2\u003eThe pierced gallery\u003c\/h2\u003e\u003cp\u003eUnderneath, the head is cut through with arches rather than left solid. Openwork like this was standard on Victorian and Edwardian rings. It lets light reach the pavilion from below, which matters on a deep antique cut, and it turns the side of the ring into the part worth looking at.\u003c\/p\u003e\u003ch2\u003eSet low\u003c\/h2\u003e\u003cp\u003eThe head sits close to the finger instead of raised on a tall basket. That keeps the ring steady, stops it snagging, and lets a wedding band lie flat against it. Antique rings were made this way as a matter of course.\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 suits the reference best, since antique rings were rarely white. 10K is the hardest alloy, 14K the everyday balance, 18K the deepest colour. 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. An antique cut shows colour more readily than a modern brilliant because of its shallower crown angles, which is one reason we fix the grade at E.\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 gallery is pierced and filed by hand after the head is formed, so no two are identical under a loupe. 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 up through the pierced gallery from underneath. A deep pavilion collects more than a shallow one, and a dirty antique cut goes dull faster than a modern stone would. 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 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, unusually well. The head is low and the shank straight.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan it be resized?\u003c\/strong\u003e Yes, freely. The band is plain all the way round.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes it face up smaller than a modern round?\u003c\/strong\u003e Slightly, yes. An antique cut carries more weight in depth than in spread, so at the same carat weight the outline is a little narrower. What you gain is fire and character.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the culet visible?\u003c\/strong\u003e On a true antique proportion, yes, as a small dark point when you look straight through the table. It is a feature of the cut, not a flaw.\u003c\/p\u003e","brand":"Mapple Gems","offers":[{"title":"925 Sterling Silver \/ 2
