beryl

[shaman15771]

I live about 2 to 3 miles from 2 beryl mines. Has anyone got a picture of host rock? I have a small piece but too small to help much. Want to be able to keep an eye out. Mines are blue/green. Thanks a lot from confused newbie.

Depends on what kind of beryl, as in what gave the beryl its colour. Pegmatites are known for beryls, but are far from alone.

About the only thing I can offer you is that beryl is known to have or be in a hexagonal shape.. (stop sign) yet can be found as long as 10 feet or more and range in a variety of colors.. The most prized Beryl would be the golden yellow/orange which when cut could appear to be a topaz.. But seeing how my wife's eyes are baby blue.. I'll stick with the pale blue beryl. As of yet, I've never found one.. thou came close in this post: http://www.treasurenet.com/forums/rocks-gems/423132-rock-mineral-photo-techniques-refersher.html

Just to clarify. Pegmatite and mica schist are rocks. Muscovite, quartz, feldspar, tourmaline, corundum (ie. ruby and sapphire), beryl ( ie. aquamarine, emerald, bixbite or bixbyte) staurolite are minerals.

Beryl is a mineral found in pegmatites. Depending on the elements introduced into the environment while beryl the mineral is forming is going to determine what color the mineral is going to be. For example if chromium is introduced into the system as beryl is forming more than likely the mineral will be beryl var. emerald.

Rock and mineral hunting is a great hobby and passion. Below are some resources that can be found on the subject.

If you have any questions don't hesitate to ask. Good luck and happy hunting. Brian T.

Just outside of Burnsville, NC is the old Ray Mica Mine and most of the Beryl found there, is found in Feldspar which has Mica, Quartz, Tourmaline, Garnet, Amazonite and who knows what else in it. Most of the Beryl from the tailings from the Mica mining are light green, light greenish/blue and clear. Ever so often a pink, orangish/pink or a true Aquamarine specimen will be found in the tailings or creek.
