Jewelry, Gems, & Minerals/unknown crystal


hello, I recently found a crystal in a drawer. According to my mom, it was given to me by a family member who has passed away. Could you please tell me the name of the crystal and its properties, if possible?
it would mean the world to me, thank you!

Be aware that answering your question just from pictures without performing any physical testing is rather difficult, if not impossible. However, having seen my share of rocks and minerals, I can give you my first impression from the attached pictures.
At first glance the specimen looks like a polished rock with no visible crystalline structure. It was probably processed in a rock tumbler to give it the current shape and polish. Most of your specimen is most likely a variety of micro crystalline quartz, probably jasper (red), chert (brown) or agate (banded). The blue color might be some inter-layered turquoise or other silicate mineral (e.g. microcline?). Hard to tell from the picture.

I can answer questions concerning minerals, mineralogy, gems, metals, and anything that has to do with geology. However, I am NOT a jeweler. Questions about values, settings, gem stone cuts and appraisals are best directed to other experts on this site. I can however aide in the identification of unknown mineral materials. As a public service and part as training for new geoscientists, our university department provides FREE mineral identification for individuals. Please contact me for details or go to for details..
