Named after its discoverer Colonel Hendrik von Prehn, prehnite is an attractive collection mineral that is used for jewelry and occasionally used for ornamental stone purposes. Its color is usually a very beautiful green that appears in a shade that could be considered unique to prehnite. Found in association with volcanic rocks, it usually forms in aggregates and has a rather thick crust with a rough or crystalline texture. The rough texture makes it difficult for faceting but it can be cut in a cabochon to reveal its unusual color.

Gold is a remarkable, precious metal, with an unparalleled combination of chemical and physical properties. The only yellow metal, its name comes from the Old English word for yellow, 'geolu'. As the only metal that forms no oxide film on its surface in air at normal temperatures means that it will never rust or tarnish.

One of the three noble metals, gold in its pure form is a yellow metallic element. This soft metal performs best when alloyed with other metals to make it stronger. To produce rose gold, gold is alloyed with copper to create a warm pink hue.

Gold has long been considered one of the most precious metals in the world. For thousands of years it has been used as the ornament of kings and as a standard for global currencies.
