Youngite hasn’t been readily available for years. We bought this material decades ago and recently found it in our “archives”. Youngite sometimes glows bright green under UV light (black light)! It is a pretty pink brecciated agate with a translucent background and a drusy coating. Youngite makes pretty gemstones and awesome fluorescent specimens! Wearing jewelry made with Youngite stones at a party with a black light atmosphere will produce a lot attention.
