Making the Blue Lagoon Necklace with Adler Joailliers | Expert Voices

First discovered in Brazil in the 1980’s, Paraíba tourmalines have become one of the most highly sought-after gemstones in the world, frequently commanding prices that far surpass those paid for fine sapphires, rubies and emeralds. Top-quality Paraíba tourmalines are distinguished by an extraordinary electric blue hue, but specimens possessing this distinctive colour are typically small and possess a significant degree of internal imperfections. Here, the Blue Lagoon stands alone. Its impressive size, superlative clarity, and enchanting turquoise colour — all achieved without the aid of heat treatment — recall the crystalline waters of a tropical paradise.
