Pair of Amethyst Geode Halves
Minas Gerais, Brazil
Displaying the very large and superb, deep purple gem quality crystals for which the finest amethyst of the Minas Gerais region is famous, a matched pair of amethyst geode halves exhibits a desirable cathedral shape. Geodes are formed within voids produced by gas bubbles in volcanic rock, into which mineral-laden water seeps, then crystallizes over the eons. These are exceptional display specimens.
Each specimen measures approximately 26 x 26 x 9in
