Turkish Stick Agate Cabochons

Stick Agate is a formation of agate that comes from mines in Ankara, Turkey. Much of the time, this agate features stick-like formations that are 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 crystals. In some cases, these aragonite crystals form as hollow tubes that when polished will contain agate and/or druzy quartz within.
