1. Arizona Splash Copper
Arizona Splash Copper is formed from pure copper
mined in central Arizona. It is heated to a scorching
2200°F, splashed, cooled, and cleaned to give each piece
its unique shape. A second application of heat creates
the colorful patina. The metallic luster of copper in
combination with the rainbow coloring adds glimmer to
any room and decor.
2. Amethyst Geodes
Amethyst is the most valuable and regal of quartz
gemstones. Rich hues extending from light pinks to
deep purples are attributed to the presence of iron
or manganese. Volcanic in origination, amethyst
geodes are formed by cavities or bubbles in lava
which are exposed to water containing iron and
crystallized over time.
3. Jasper
Jasper is a patterned form of chalcedony quartz,
generally opaque and found in virtually any color.
Comprised of impure silica, jasper is common,
varied, and usually found in deep hues of red,
yellow brown or green. Polychrome Jasper or
Desert Jasper is a relatively new find in the Mineral
World.
4. Malachite
Malachite is an intensely green stone known for its
distinctive veining, patterning, and orbicular quality.
This gemstone is a copper carbonate formed from
copper containing solutions near copper ore deposits.
Many spectacular green and blue specimens include
deposits of azurite and chrysocolla incorporated into
the malachite.
