It comes in two sizes, EU 56 and EU 58. House Of The 18th put a stone that shifts colour with the light next to one that holds a single, steady blue.\u003c\/p\u003e\n\u003ch3\u003eWhat is blue topaz?\u003c\/h3\u003e\n\u003cp\u003eTopaz is a naturally colourless aluminium silicate mineral. This stone's blue comes from irradiation and heat treatment, the standard process behind nearly all blue topaz on the market. It rates 8 on the Mohs scale, among the more durable stones House Of The 18th works with.\u003c\/p\u003e\n\u003ch3\u003eWhat is iolite, and why does it look different from different angles?\u003c\/h3\u003e\n\u003cp\u003eIolite is the gem form of cordierite, and it's strongly pleochroic — meaning it shows different colours depending on the angle it's viewed from, shifting between violet-blue and a smoky grey-yellow. This optical effect is natural to the mineral and isn't a result of treatment. Iolite rates 7 to 7.5 on the Mohs scale.\u003c\/p\u003e\n\u003ch3\u003eWhy set a colour-shifting stone next to a fixed one?\u003c\/h3\u003e\n\u003cp\u003eTopaz gives the ring one dependable colour from any angle. Iolite gives it a second colour that only shows up when the hand moves. House Of The 18th set them together so the ring reads differently depending on whether it's still or in motion.\u003c\/p\u003e\n\u003ch3\u003eHow to care for topaz and iolite\u003c\/h3\u003e\n\u003cp\u003eBoth stones are hard enough for daily wear, but should still be removed before contact sports, manual work, or ultrasonic cleaning, which can stress faceted stones over time. Clean with a soft cloth and avoid harsh chemicals, which can dull the plating around the settings.\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\u003eBlue topaz, brilliant-cut; iolite, round-cut, faceted\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRing sizes\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eEU 56, EU 58\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSetting\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eProng-set\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eHypoallergenic\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eIs the topaz on this ring natural or treated?\u003c\/strong\u003e The topaz is irradiated and heat-treated to reach its blue colour, which is standard practice across nearly all blue topaz sold commercially and is not the stone's original colourless state.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is iolite and is it treated?\u003c\/strong\u003e Iolite is a naturally pleochroic gemstone, meaning its colour genuinely shifts with viewing angle, and it is rarely treated, unlike many of the other coloured stones in this collection.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does 18ct gold-plated mean?\u003c\/strong\u003e 18ct gold-plated describes a thin layer of 18-carat gold applied over the 925 sterling silver base, referring to the gold's purity rather than the ring's overall carat weight.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow durable is this ring for daily wear?\u003c\/strong\u003e Both stones rate 7 to 8 on the Mohs scale, making this one of the more durable rings in the collection and well suited to daily wear with normal care.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan this ring be stacked with other rings?\u003c\/strong\u003e Yes, and it's available in EU sizes 56 and 58 to fit alongside other pieces in a stack.\u003c\/p\u003e","brand":"House Of 18th Jewellery","offers":[{"title":"56","offer_id":53448211005706,"sku":"RS1642TI.3","price":68.0,"currency_code":"EUR","in_stock":true},{"title":"58","offer_id":53538055160074,"sku":null,"price":68.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/0161\/5370\/files\/IMG_3976_JPG.jpg?v=1785328648","url":"https:\/\/houseof18thjewellery.com\/products\/silver-ring-with-topaz-and-iolite-18-carat-gold-plated","provider":"House Of 18th Jewellery","version":"1.0","type":"link"}
