Edged with milgrain and dotted with tiny diamonds, it is one of the most distinctive vintage inspired designs we make.\u003c\/p\u003e\u003ch2\u003eAt a glance\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCentre stone: Oval brilliant 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: Compass star halo with milgrain edges\u003c\/li\u003e\n\u003cli\u003eAccent stones: Round brilliant laboratory grown diamonds in the halo and points, 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 halo with direction\u003c\/h2\u003e\u003cp\u003eMost halos simply follow the outline of the centre stone. This one extends into four points, each tipped with a tiny diamond, giving the head of the ring a kite or star shaped silhouette. It draws on Art Deco and Edwardian jewellery, where geometric halos and milgrain borders were used to make a centre stone look larger and more dramatic. The effect is both celestial and antique, and it makes a 2 carat oval read as a far bigger jewel.\u003c\/p\u003e\u003ch2\u003eThe oval brilliant\u003c\/h2\u003e\u003cp\u003eAn oval carries brilliant faceting in an elongated outline. It looks larger for its carat weight than a round because more of its surface faces up, and it lengthens the finger. The compass points exaggerate that length even further.\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. Rose gold gives the star a soft, romantic glow, yellow gold a warm antique look, and white gold a crisp, frosty finish. 10K is the hardest alloy, 14K is the everyday balance, and 18K is the richest colour but the softest metal. 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 compass halo is built around your oval, the milgrain is applied by hand and every accent is set under a microscope. 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 gently around the halo points. 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. The halo stones are matched to the same grade.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo the points catch on clothing?\u003c\/strong\u003e They are rounded and low, so they rarely catch.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine antique?\u003c\/strong\u003e No. It is newly made to order in a vintage inspired style.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill a wedding band sit flush?\u003c\/strong\u003e A curved or notched band sits best against the compass points.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan it be resized?\u003c\/strong\u003e Yes.
