It is sized EU 58 (18.5mm inner diameter) and supplied as a single piece. The peridot reads bright and glassy, the green onyx darker and steadier, so the band shows two depths of the same colour.\u003c\/p\u003e\n\u003ch3\u003eWhat is peridot?\u003c\/h3\u003e\n\u003cp\u003ePeridot is the gem variety of olivine, a magnesium iron silicate that rates 6.5 to 7 on the Mohs hardness scale. Peridot only occurs in green, because the colour comes from iron built into the crystal itself rather than from trace impurities. Peridot is one of the few coloured gemstones sold essentially untreated, so its green is the colour it formed with.\u003c\/p\u003e\n\u003ch3\u003eWhat is green onyx, and is it dyed?\u003c\/h3\u003e\n\u003cp\u003eGreen onyx in the jewellery trade is almost always chalcedony, a microcrystalline quartz, dyed to an even green, because chalcedony rarely grows in that colour on its own. Assume the green onyx in this ring is dyed. It rates 6.5 to 7 on the Mohs scale, about the same as the peridot beside it.\u003c\/p\u003e\n\u003ch3\u003eWhy mix a treated stone with an untreated one\u003c\/h3\u003e\n\u003cp\u003ePeridot needs nothing to be green. Green onyx needs dye. House Of 18th Jewellery set them on the same band and says so, because a ring that lets you assume every stone is equally natural is hiding something about one of them.\u003c\/p\u003e\n\u003ch3\u003eHow to care for peridot, green onyx and gold plating\u003c\/h3\u003e\n\u003cp\u003eTake the ring off before showering, swimming, washing up or putting on hand cream. Peridot is sensitive to acids and sudden temperature change, so never use an ultrasonic or steam cleaner, and do not soak dyed stones or clean them with solvents. Wipe with a soft dry cloth only, because polishing cloths and silver dips remove gold plating. Store it on its own in a soft pouch.\u003c\/p\u003e\n\u003ch3\u003eHow long the gold plating lasts\u003c\/h3\u003e\n\u003cp\u003eGold plating is a finish, not a material. With daily wear it typically holds for one to two years before it begins to show thinning at high-contact points — the underside of a band, the back of a pendant — and considerably longer on pieces that come off before water, perfume and sleep. The 925 sterling silver underneath does not wear out, and the plating can be renewed by a jeweller.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMetal\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e925 sterling silver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFinish\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e18ct gold-plated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eStones\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePeridot and green onyx, 1.5mm to 2mm each, hand-set individually\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eStone treatment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePeridot: none.
