Two Mineral crystal

The earliest forms of jewelry were items that early humans found naturally, such as shells or bits of bones. Early gravesites have also revealed that pre-historic man buried his dead with flowers and with carved ivory beads. These primitive beads would have taken at least an hour each to make.
Early man also might have found bits of turquoise that occurred naturally in areas of Turkey and North America. The pearlescent swirls found inside an abalone or conch would have also been used as jewelry.
They might have also found the earliest types of precious gems in the form of natural crystals, such as quartz or diamonds. Crystals are solid substances where the molecules are arranged in a symmetrical fashion, and they generally fall into one of six shapes:
Isometric, or cubic crystals are shaped like blocks and are symmetrically shaped. An example of an isometric crystal would be pyrite. This is also called fool’s gold because it has a metallic yellow or brassy color similar to gold.

Much rose quartz was extracted from a famous site near Custer, South Dakota, but now, most of the world’s supply comes from Brazil. Rose quartz is one of the most valued varieties of quartz. The pink to rose red color is unique.
The color of rose quartz is still not completely understood. It has been said to be due to a number of different minor impurities present in the rose quartz including titanium, manganese and even colloidal gold. However, recent studies using micro-analytical methods have discovered that the color of massive rose quartz is actually due to microscopic mineral fibers in the rose quartz. X-ray diffraction tests…
