It sits on a slim, plain band that keeps all the attention on the head.\u003c\/p\u003e\u003ch2\u003eAt a glance\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCentre stone: Round 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: Sunburst cluster halo on a plain band\u003c\/li\u003e\n\u003cli\u003eAccent stones: Round brilliant laboratory grown diamonds in two sizes, 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 sunburst, not a halo\u003c\/h2\u003e\u003cp\u003eA standard halo is a neat ring of equal stones pressed tight against the centre. Here the surrounding diamonds are larger, spaced apart and alternated in size, so the outline becomes a scalloped star rather than a circle. Each accent catches the light independently, and the whole head looks bigger, bolder and more alive. The design draws on the cluster rings of the Georgian and Victorian eras, when sunbursts and starbursts were favourite motifs.\u003c\/p\u003e\u003ch2\u003eHow it differs from our other round halo rings\u003c\/h2\u003e\u003cp\u003eOur other round halos use small, uniform stones. This one uses larger alternating accents set in individual claws, which makes it the most dramatic and vintage looking of the group.\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 and yellow gold give the sunburst a warm, antique glow. 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. Each accent diamond is claw set individually around your round 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 between the accent stones, where dust gathers. 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 sunburst diamonds are matched to the same grade.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow big does the head look?\u003c\/strong\u003e Considerably larger than the centre stone alone, as the sunburst adds several millimetres all round.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the cluster catch on clothing?\u003c\/strong\u003e The claws are rounded and smooth, but as with any raised cluster, take care with fine knits.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill a wedding band sit flush?\u003c\/strong\u003e A curved or notched band suits the wide head best.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan it be resized?\u003c\/strong\u003e Yes.
