Could you hrlp my 6 year old sin and I identify this stone

Answer
Hello there,
It is always a little tricky to identify minerals just from pictures without doing some quick physical tests. However ,let me give it a try. From the shape and the crystal form that is shown you most likely have a mineral crystal that belongs to the Garnet Group. Garnets are minerals that can be gem quality if they are clear and translucent. Using the color of the picture as a guide, your garnet crystal (if it indeed is a garnet) is most likely the garnet mineral Andradite (Ca3Fe2(SiO4)3).
Garnets from usually only under high pressure conditions deep within the earth, over 5 miles down.

Expertise

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 http://college.earthscienceeducation.net/MIN/MINID.pdf for details..

Experience

I am a professor of applied geology and mineralogy with many hours of field experience. Furthermore, I enjoy recreational gold prospecting and mineral collecting. As a professor I am engaged in research concerning minerals and their occurrence.
