October is home to two of the most extraordinary gemstones in the birthstone calendar — opal and tourmaline. Opal shifts colour as it moves, no two stones ever identical. Tourmaline comes in more natural colours than virtually any other gem, often displaying multiple hues within a single crystal.
Discover October birthstone jewellery in silver, gold and rose gold finishes, from opal necklaces and pendants to black tourmaline bracelets. Each piece is handcrafted in our UK studio using genuine stones, gift-ready in our signature Abiza box.
Choose opal for its iridescent play of colour, or black tourmaline for its protective, grounding energy. Both are meaningful October birthday gifts — and both are the traditional stone for landmark wedding anniversaries (opal at 14 years, tourmaline at 8).
