Obsidian A naturally occurring volcanic glass. Pronounced: 'ob-sid-e-un'

Moldavite Opal


Crystals (UK) obsidian is from Mexico.


Natural glass formed from rapidly cooling lava from a volcano. The speed of cooling was so fast that crystals did not have time to form. Obsidian can be fractured to produce sharp edges and has been used since pre-historic times for cutting tools, arrowheads, ornaments and jewellery. It was even polished to make a primitive mirror!


Mainly silicon dioxide: SiO2


Amorphous (no distinct crystal structure). A rough surface in natural state with distinctive jagged, scarred texture. Concoidal fracture.


These can produce a metallic sheen (e.g. rainbow obsidian or goldsheen/silversheen obsidian) caused by internal gas bubbles or crystals of cristobalite to produce a snowflake effect (snowflake obsidian). Mahogany obsidian has a high concentration of iron.

Our View

Much of our carved obsidian is crafted by a single family who we meet once a year. The father’s hands are well scarred from this very sharp material. Their challenge is to artistically highlight the sheens and patterns in individual pieces.

Highly skilled Chinese carvers produce our top end pieces, such as the largest AA Grade hearts. For the last two years we have selected rough obsidian and arranged shipment to our Chinese carvers from whence it returns via Hong Kong! This can take up to a year but we believe the obsidian we sell is amongst the finest, if not THE finest, in Europe.

Our commitment to obsidian is an example of our developing and encouraging appreciation of a ludicrously neglected stone. How often we heard ignorant people suggesting it was not worthy of gold settings or use in large bangles! How sadly misguided!
