3.8" Turkish Stick Agate Slab - Turkey

Stick Agate, also known as "Needle Agate", is a formation of agate that comes from mines in Ankara, Turkey. This agate often features stick-like formations surrounded by agate. This occurs when agate fills a cavity within a rock that already contains mineral formations throughout. In the case of these stick agates from Turkey, the agate formed as a pseudomorph after aragonite and/or sagenite crystals. In some cases, these aragonite crystals form as hollow tubes that, when polished, contain agate and/or druzy quartz within.
