Natural Carnelian Gemstones

Carnelian Rough

Carnelian is a brownish-red to red-orange variety of chalcedony or cryptocrystalline quartz. Its name is believed to come from the Latin word carneus, meaning 'flesh coloured'. The distinctive red-orange color of carnelian is a result of trace amounts of iron. Sometimes the name 'sard' is used to refer to the darker colors of carnelian, though there is no clear distinction between carnelian and sard.

Carnelian is one of the oldest known gemstones. It was widely used in ancient Rome to make insignia and seals for imprinting on letters or important documents because hot wax does not stick to carnelian. Carnelian is one of the twelve gemstones mentioned in the Bible as appearing on the Breastplate of Aaron. It also is one of the birthstones listed in the ancient Arabic, Hebrew and Roman tables, and is a birthstone for the zodiacal sign of Virgo.

Natural Carnelian Cabochon

Like other chalcedony, carnelian has a hardness of 6.5 to 7 on the Mohs scale, and a density of 2.58 to 2.64. It has a refractive index of 1.530 to 1.540. It ranges in clarity from translucent to opaque.

Today, carnelian is used for cabochons and beads. It is also carved to produce cameos, intaglios and other sculptures. The most important carnelian deposits are found in Brazil, Uruguay, India and Madagascar.

Carnelian Cameo

Many carnelian gemstones being offered for sale on the market today are actually agate gemstones that have been dyed and then heat-treated. But there is a way to identify natural carnelian. The dyed agate will display striping when held against the light, while the natural carnelian will show a cloudy distribution of color. Natural carnelian is becoming increasingly rare.

Since carnelian has such a long history, it is not surprising that a great deal of folkore and legend has become attached to it. Carnelian was regarded as one of the luckiest gems to wear. A proverb states that "No man who wore a carnelian was ever found in a collapsed house or beneath a fallen wall." Carnelian was used as a talisman by people dating back as early as the ancient Babylonians and Greeks. Many Muslims believe that carnelian brings peace and happiness to its owner. This belief is attributed to the fact that Mohammed wore a ring set with a carnelian seal. Emperor Napoleon jealously guarded a carnelian seal that he found in an Egyptian campaign and often wore as a watch charm.

As long as I continue to have confidence that what I am buying is genuinely what is being advertised then I am happy. If an item is listed as natural but is actually lab created, well that would be the last time I support this company.

So many stones, so little time and money. Easy to fill up the cart when the stones are beautifully pictured. I hope the real items are as beautiful.

I recently bought some stones for Christmas gifts for my family from GemSelect and was thrilled at the speed they arrived to me. The descriptions were accurate and could be verified by myself upon receiving the stones, though the only issue i had was finding exact stones i wanted. The sorting system is fanastically detailed, but often seems to trim more results than expected when i was selecting things to look by. They arrived safely and all together, as described per my purchase order and i could not be more satisfied. There aren't many that are looking to buy loose stones like this, but it really gets the job done.
