Black Tourmaline Sterling Silver Rectangle Trinity Ring

TourmalineTourmaline is the alternate birthstone for October, for those not keen on the superstitions surrounding Opal! Tourmaline has a variety of colours. Usually, iron-rich tourmalines are black to bluish-black to deep brown, while magnesium-rich varieties are brown to yellow, and lithium-rich tourmalines are almost any colour: blue, green, red, yellow, pink, etc. It is rarely colourless. Bi-coloured and multicoloured crystals are common, reflecting variations of fluid chemistry during crystallization. Crystals may be green at one end and pink at the other, or green on the outside and pink inside; this type is called watermelon tourmaline.ACCORDIONSterling Silver (925%)Why do silversmiths use 925%? Measured in parts per thousand, pure silver (999%) is too soft so silversmiths mix it with other metals to make it it harder. The purer the metal, the higher the polish, but it is a lot softer (thus less durable). The harder the metal is, the more hard wearing the jewellery is, but it will also tarnish easier as it has less silver content. Therefore, the silver industry set a standard percentage content for fine silver (925); what we know as "sterling silver". At Two Skies our silversmiths use 925 (sterling) silver for ring shafts and moving parts, and a very high 950% on our stones settings, which enables us to get a strong jewellery item with a beautiful and secure stone setting, without any gluing. Each piece of our jewellery is hand stamped with our Two Skies Hallmark alongside the recognised industry 925 Hallmark.ACCORDIONReturns & Refund PolicyRelax - you can shop with confidence at Two Skies.
