{"product_id":"oval-cut-lab-grown-diamond-hidden-halo-station-set-band-ring","title":"Oval Cut Lab Grown Diamond Hidden Halo Engagement Ring with Station Set Accent Band in Silver, 10K, 14K and 18K Gold","description":"\u003cp\u003eAn oval laboratory grown diamond on a hidden halo, above a band so fine it reads as a wire, with single round diamonds set at intervals along it. Each accent sits alone in its own bead setting with clear polished metal on either side, so the shoulders read as a line of separate points of light rather than a continuous row of pave.\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: Four claw oval with a hidden halo on a fine station set accent band\u003c\/li\u003e\n\u003cli\u003eAccent stones: Round 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\u003eStation set, not pave\u003c\/h2\u003e\u003cp\u003ePave packs stones shoulder to shoulder. Station setting places them one at a time with a deliberate gap between each. It uses fewer diamonds, it is far easier to keep clean because there are no tight seams to trap dust, and it suits a delicate band that could not structurally carry a full row. It also means the eye travels along the band rather than reading it as a solid strip.\u003c\/p\u003e\u003ch2\u003eThe hidden halo\u003c\/h2\u003e\u003cp\u003eSet into the vertical wall of the basket rather than around the top of the oval, the halo is invisible from above and unmistakable from the side. It lifts the centre stone clear of the finger and lets light reach the pavilion from underneath, which is why the diamond looks brighter than the same stone in a closed setting.\u003c\/p\u003e\u003ch2\u003eWhy the band is so thin\u003c\/h2\u003e\u003cp\u003eLess metal beside the stone makes the stone look bigger. The eye has nothing to measure the oval against except the finger. At 4 and 5 carat the band nearly disappears and the diamond appears to float, which is the whole point of this design.\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. On a band this fine we would gently steer you towards 10K or 14K, which are harder alloys and hold a thin shank better over years of daily wear. Yellow gold, as photographed, reads as a warm thread against a very white stone. 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 station is drilled and beaded individually, and the hidden halo goes in before the centre stone does. 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. The spaced stations rinse clean in seconds, but do turn the ring over and brush the hidden halo. 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 station accents and halo stones are matched to the same grade.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs a thin band strong enough for a 5 carat stone?\u003c\/strong\u003e Yes, but choose 10K or 14K rather than 18K if you want the most rigid shank, and have it checked every couple of years like any fine band.\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 Almost. The hidden halo lifts the centre slightly, so a straight band sits close and a gently curved band sits perfectly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan it be resized?\u003c\/strong\u003e Yes, within a size or two. The stations stop well before the back of the band.\u003c\/p\u003e","brand":"Mapple Gems","offers":[{"title":"925 Sterling Silver \/ 2
