What is a semi-precious stone?

The two terms precious and semi-precious are not widely used these days. The designation began in part because diamond, ruby, sapphire and emerald were taxed at a higher rate than other gemstones. Many people think semi-precious indicates a gem of lesser value and hardness, which is not true, and the main reason why the term semi-precious is no longer widely used.

What is a gemstone?

A gemstone is a stone used for personal adornment that is beautiful, durable, and stable. Beauty is based on color, luster, transparency, or cutting and shaping with lapidary techniques. Durability is the resistance to damage and is dependent on hardness and tenacity. Tenacity is the resistance to bending and breaking, while hardness measures the resistance to scratching. Stability refers to the gem's ability to retain color in spite of heat, light, or chemical changes.

Agate Gemstone CabochonAgate is a microcrystalline form of quartz or silica, chiefly chalcedony, known for its fine grain and bright color. Although agates may be found in various kinds of rock, they are typically associated with volcanic rocks. Most agates occur as nodules in volcanic rocks or ancient lava. Formed by cavities in the lava which were filled with silica deposited in layers. You can see these layers in banded agate.  Healing Properties  Cabochons
Alabaster CabochonAlabaster is a name given to two distinct types of minerals: gypsum and calcite. In ancient times the term alabaster was applied to calcite. Today, the term refers to a fine grained variety of gypsum.  Gypsum is harder than calcite and does not scratch as easily.  Healing Properties 
Amazonite Gemstone CabochonAmazonite is a microcline form of feldspar and although the name is taken from that of the Amazon River, it is highly unlikely that it was ever found there. In the past it's only source was a mountainous area in Russia. More recently, high-quality crystals have been obtained from Colorado, where it is found in conjunction with quartz, orthoclase, and albite in granite. Some other localities in the United States yield amazonite, and it is also found in Madagascar.  Healing Properties  Cabochons
