Exploring the Paraiba Tourmaline’s Allure

Paraiba tourmalines, first discovered in Brazil during the 1980s, have established themselves as some of the most coveted gemstones in the world. Their vibrant electric blue hue sets them apart, often fetching prices that surpass even the most esteemed sapphires, rubies, and emeralds.

However, it’s crucial to note that genuine top-quality Paraiba tourmalines bearing this distinctive colour are usually small and possess numerous internal imperfections. But in this narrative, The Blue Lagoon stands alone. It boasts an impressive size, exceptional clarity, and a captivating turquoise hue, all achieved naturally, without the intervention of heat treatment, reminiscent of the crystalline waters of a tropical paradise.

Adler Joailliers: Masters of Craftsmanship

To enhance the evocative nature of the stone, Adler Joailliers has meticulously designed a waterfall of shimmering round, marquise, and pear-shaped diamonds, collectively weighing over 76 carats. This design embodies the essence of sophistication in its simplicity, a style that the family-owned firm describes as “classic with a twist.”

The Blue Lagoon necklace is the epitome of Adler’s signature high jewellery, a fusion of exquisite craftsmanship and pure, timeless style. The Paraiba tourmaline comes complete with a Bellerophon report brochure and an SSEF report, both attesting to its extraordinary size and quality. Additionally, the necklace is accompanied by the original sketch by Adler for its design, along with GIA reports for select diamonds.

A Rare Mozambican Gem

Such a natural tourmaline, renowned for its size and quality, is exceedingly rare. This magnificent gem, originating from Mozambique, boasts unparalleled clarity and natural colour, without the influence of heat treatment. Copper-bearing tourmalines, initially discovered in Brazil, gave rise to the term “Paraiba,” named after the region where these vividly coloured tourmalines were first mined.

In recent years, Mozambique has emerged as the world’s foremost source of Cuprian tourmalines, including the coveted “Paraiba” varieties. This label now encompasses greenish-blue specimens of vivid to deep saturation, regardless of their mining origin. Mozambique has steadily gained recognition as a premier source of top-quality coloured gemstones.

The upcoming Sotheby’s auction promises to be a true celebration of natural beauty and exceptional craftsmanship. With the spotlight on Adler Joailliers’ Blue Lagoon necklace, featuring the exquisite Mozambican Paraiba tourmaline, and the rich legacy of Mozambique’s gemstone treasures, this event is not to be missed.
