The band is thin and plain, which lets the cluster sit on the finger like something growing rather than something mounted.\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: Floral cluster, oval centre with marquise and pear petals, on a thin plain shank\u003c\/li\u003e\n\u003cli\u003eAccent stones: Marquise and pear cut 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\u003eA cluster, not a halo\u003c\/h2\u003e\u003cp\u003eA halo is a ring of small identical stones set tight against the centre to make it look larger. A cluster is something else: the surrounding stones are large enough and shaped enough to be part of the design in their own right. Here they are marquises and pears, set point outward at even intervals, so the outline of the ring is scalloped rather than smooth and the whole head reads as a flower in bloom.\u003c\/p\u003e\u003ch2\u003eWhere the shape comes from\u003c\/h2\u003e\u003cp\u003eCluster rings of this kind were common in the Georgian and Victorian periods, when large single stones were rare and expensive and jewellers made impact by grouping smaller ones. The form came back through the 1960s and 1970s, and it has returned again with people who want something that looks nothing like a modern solitaire.\u003c\/p\u003e\u003ch2\u003eThe petals\u003c\/h2\u003e\u003cp\u003eEach marquise and pear is set in its own claws rather than shared beads, with the points angled outward from the centre. Setting them individually is slower but it keeps the spacing even and lets each stone sit at a slight tilt, which is what stops the cluster from looking flat and makes it catch light from several directions at once.\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 a warm metal is the traditional choice for a floral cluster because it reads as the stem and calyx holding the flower together. 10K is the hardest alloy, 14K the everyday balance, 18K the richest 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. Every petal stone is matched to the same E and VVS2 grade, which matters here because the accents are large enough to be judged individually.\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 petals are laid out around your particular centre stone so the flower stays symmetrical at whatever carat weight you choose, and each pointed tip is set inside a claw rather than left exposed. 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. A cluster has more crevices than almost any other setting, so work the brush right round between the petals and up into the head from underneath. 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 marquise and pear petals are matched to the same grade.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the carat weight include the petals?\u003c\/strong\u003e No. The 2, 3, 4 and 5 carat options refer to the centre oval. The surrounding stones are in addition and are scaled to keep the flower in proportion.\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 The cluster overhangs the shank, so a straight band leaves a gap beneath the petals. A curved or contoured band follows the outline much better.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan it be resized?\u003c\/strong\u003e Yes, easily. The whole band is plain metal, so one or two sizes either way is straightforward.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo the pointed stones chip?\u003c\/strong\u003e Not when they are set properly. Every marquise and pear tip on this ring sits inside metal rather than standing exposed at the edge of the cluster.\u003c\/p\u003e","brand":"Mapple Gems","offers":[{"title":"925 Sterling Silver \/ 2
