Tourmaline

"No gemstone on earth offers a wider spectrum of colour — from electric pink to deep forest green, all in one stone."

Tourmaline is a gemstone celebrated for its extraordinary range of colours and remarkable versatility. Known as the "Rainbow Gem," tourmaline encompasses a diverse spectrum of hues — from deep blues and vivid greens to bright pinks, rich reds and warm browns. Its captivating beauty and wide colour variety make it one of the most sought-after gemstones for both collectors and jewellery designers worldwide. Tourmaline is associated with balance, creativity and emotional well-being, embodying the full richness of nature's palette.

Tourmaline's vibrant colours and excellent durability make it a premier choice for a wide range of jewellery. It is used in rings, necklaces, earrings and bracelets, where its stunning hues can be prominently displayed. Tourmaline pairs beautifully with gold and silver, and is often accented with diamonds or other complementary gemstones. Its diverse colour range makes it suitable for both classic and contemporary designs — offering jewellers virtually unlimited creative possibilities.

At Karen Brand Limited, we source our tourmaline from the finest mines in Ethiopia and Kenya. Our team ensures that each piece is ethically mined and meticulously inspected for colour intensity, clarity and quality. We offer both rough and cut tourmaline — including green, pink and multi-colour varieties — to suit wholesale buyers, jewellers and collectors.
