    Vorobyevite Beryl on Kimberlite


    Just this year at Great Lakes Beryl we have identified clear goshenite beryl, red pezzottaite beryl, blue vorobyevite/rosterite beryl, and golden beryl.  Our spectacular kimberlite pipe discovery was made by Anthony Thomas in 2022 in Marinette County Wisconsin.  See our collection of rough gemstones, one-of-a-kind cabochons, and incredible rare specimens offered at Anthony Thomas Fine Metal & Gems.  Visit anthonythomas.us.
