Natural Lagoon Tourmaline 0.90 Carat | Cushion Cut Loose Gemstone from Afghanistan
Overview

Sourced from Afghanistan and fully untreated, it is small in size but clean and well saturated, a good fit for delicate, elegant jewelry.

Symbolism
Lagoon tourmaline is traditionally associated with emotional balance, confidence, inspiration, and calm. (Folklore-based; not a medical claim.)
