Chalcedony

Why Buy chalcedony gemstones?

Chalcedony, or calcedony, is a fine-grained variety of the silica mineral quartz. It has a waxy luster and appears in a great variety of colors - usually blue-white, buff, light tan, gray, yellow or brown. Chalcedony is named after the ancient seaport of Chalcedon (Kadikoy, Turkey). Archaeologists have dug up Babylonian and Assyrian chalcedony cylinder-seals dating from 500 BC. Common forms of chalcedony include agate, bloodstone, jasper, bloodstone, and onyx, among others.

What are some of the properties of chalcedony gemstones?

Chalcedony is typically cut as cabochon gemstones. Cabochon style cutting accentuates the glow that made Chalcedony desireable. On the Mohs scale of hardness, it is a 6.5 - 7 out of 10 which makes it a durable gem type that is suitable for numerous types of jewelry.

What are good ways to use chalcedony gemstones?

Some of the types of gems in this family are quite common, so this gem type is sought after by professional and amateur jewelers. Because of Chalcedony's durability, it is suitable for any type of jewelry even pieces that are to be worn daily such as rings and pendants.

GemSelect has a great selection of smaller cabochons. Many other retailers do not. Plus, the photo of the stone is the one you are purchasing. Shipping from Thailand is nearly as fast as from within the US. Stones are tightly and neatly packaged.

Picking a garnet to match a setting. Good selection, It would have been better if a side by side color comparison was possible.
