This page gathers the stones in our collection whose origin is recorded as Ethiopia. Ethiopian material is best known for opal, and here it sits alongside Paraiba tourmaline — two very different expressions of colour, one built on diffraction, the other on chemistry.
Ethiopian opal owes its play-of-colour to an ordered structure of microscopic silica spheres that diffract light into moving flashes of spectral colour. Much Ethiopian opal is hydrophane, meaning it is porous and can absorb water, so it asks for more considered care than most gem materials: avoid prolonged immersion, ultrasonic cleaning and sudden temperature change. Paraiba tourmaline takes its name from a colour type rather than a single locality — the characteristic neon blue to blue-green is caused by traces of copper within the tourmaline structure, and the finest examples show a luminous, almost glowing saturation.
When choosing between them, weigh intended wear against character. Opal is prized for its individuality — no two patterns repeat — but is softer and better suited to pendants, earrings and protected settings. Paraiba tourmaline is considerably more durable and holds its colour in constant light. Where a stone has been heated or otherwise treated, that is noted on its individual listing.
