A PARAIBA TOURMALINE AND DIAMOND CLUSTER RINGThe central circular-cut Paraiba tourmaline weighing approximately 1.55ct within a four-claw setting and surround of brilliant-cut diamonds, mounted in platinum, diamonds approximately 1.00ct total, ring size MAccompanied by a report from the LFG laboratory in Paris (Laboratoire Français de Gemmologie) stating that the tourmaline Paraiba weighing approximately 1.55ct is of Brazilian origin, with no indication of treatment. Report number 385687, dated November 9th 2021The origin of the Paraíba Tourmaline’s name is a combination of its gemstone family, Tourmaline, and the location of where the bright blue stone was first found, in Paraíba, Brazil. The stone was discovered in the early 1980’s by Heitor Dimas Barbosa, a small-scale miner working in the area. This rare gem consists of a high level of copper and manganese which gives it its distinctive vivid, electric blue-green hue. Within a short space of time, the market rapidly absorbed the modest supply of the Paraíba Tourmaline found in Brazil and captivated by the glowing, almost neon appearance of this magnificent stone, the search was on to find a greater supply further afield. More recent discoveries of similarly-coloured tourmalines have been found in Mozambique and are sourced from a limited amount of countries in East Africa, yet their origin is denoted by their title, as these stones are only termed ‘Paraíba-like’, as a reference to the original stone. The Brazilian Paraíba Tourmaline still creates a buzz on the market today as the most expensive and highly-sought after of all tourmalines, due to its striking colour and rarity.Condition Report: Tourmaline Paraiba: of neon-blue hue, good transparency, medium tone, facets are smoothDiamonds: approx. 1.00ct total, estimated colour G/H, estimated clarity VSSuperficial signs of wear, overall in good conditionTotal gross weight approx. 8.3g
