Rare large faced rough of green malachite, blue azurite and yellow volborthite in petrified wood (Pinus). In 2012, gold prospectors in the Tolkat province of Turkey discovered a petrified log. The log was silicified and had secondary deposition of copper minerals including azurite (blue) and malachite (green). Copper mineralization of petrified wood is very rare, and other known sites don’t produce silicified examples like this. The tree this piece was recovered from has been identified as being in the Pinus genus (similar to modern Pine). Only one log was found, and the site has since been depleted. This large attractive rough shows blue, green and even some nice bright yellow volborthite. There are areas of quartz druzy and malachite crystals. A knot mineralized with malachite is especially cool. Great addition to any petrified wood collection. NOTE – the face cut is the original mine cut and has some saw marks. Pictured wet and dry with ruler under multiple lighting conditions.
