Description
A natural tourmaline in the glowing, pool-water blue-green that copper produces and almost nothing else does — the colour the trade calls Paraiba. It weighs 1.09 carats and measures 7.81 x 5.89 x 3.57 mm, cut as an oval. We describe it as Paraiba-type rather than Paraiba, and the distinction is deliberate: the Paraiba name belongs to copper-bearing tourmaline whose chemistry a laboratory has confirmed, and this stone reached us without a report. The colour is the reason it is priced where it is. If you would like it independently tested before it ships, ask us and we will arrange it. Set it as the centre of your own ring in our ring builder, or buy it loose and keep it for a design of your own. Every stone ships insured, worldwide, with our own inspection behind it.

To preserve the beauty and longevity of your gemstone, we recommend gentle care. Clean the stone using warm soapy water and a soft brush, avoiding harsh chemicals or ultrasonic cleaners unless the gem type is known to be safe for those methods. Store your jewelry separately in a soft pouch or box to prevent scratches from harder materials. Always remove gemstone jewelry during vigorous activities—such as exercising, swimming, or using household cleaners—to protect it from impact, heat, and chemical exposure. Regular professional inspections are encouraged to ensure settings remain secure and the stone stays in optimal condition.
