Star Galaxy Gold knife block with a geode

Details

Knife block made of Star Galaxy Gold with gold plating on the back and a geode.

A geode forms as a gas bubble in hot magma or lava. The outside consists of a solid layer of silicates, with joint compounds of silicon and oxygen. Inside there was a cavity filled with water in which minerals dissolved. These settle at the edge over time. There a layer of quartz crystals forms, such as amethyst and rock crystal and sometimes calcite.

The Star Galaxy Gold from India exudes a sparkling and luxurious ambience. It is particularly impressive due to its gold and bronze-colored inclusions that sparkle on its deep black background. When polished, its full radiance comes into its own. The stone fits into any living environment that relies on strong contrasts. Simply elegant and timeless. The reflective minerals are bronzites embedded in a dark matrix. The Star Galaxy Gold is a gabbro and not granite. A gabbro is a fine-grained igneous rock that was formed deep in the earth's interior. It consists mainly of dark minerals such as pyroxene, hornblende and olives; quartz is absent or only occurs in trace amounts.
