Orange Gemstones: A Guide to Colored Stones

Orange Gemstones from GemSelect - Large Image
Buy Natural Orange Gemstones from GemSelect

When it comes to colored gemstones, color is king. Today, many customers prioritize color and are less concerned with the actual gemstone variety as long as the stone is durable enough for their purpose.

However, finding gems by color can often be very difficult especially since gemstone dealers tend to list availability by gem type or gem variety rather than by gem color.

Using our guide below, you can learn about some of the most popular orange gemstones choices available today:

Orange Agate

Agate is banded chalcedony quartz that occurs in many different colors. Orange agate gemstones include Dryhead agate from Montana, Lake Superior agate and Laguna agate from Chihuahua, Mexico. Agate gemstones can be found as beads, cabochons, faceted gems, agate geodes, carvings, slices or as tumbled stones. Agate geodes are fashioned into gemstones and slices, which have an interesting "raw" look. People have used agate as gemstones since ancient times due to its pleasing colors and waxy luster.

Amber is a golden yellow to honey brown organic gemstone formed from the fossilized tree resin of the Pinus succinifera tree. Some amber gemstones contain trapped insects and other inclusions that became trapped in the resin before it hardened and some of these are especially prized, as well as transparent, rather than translucent amber stones. Amber has a very low density and since it lacks hardness, it requires a little care to avoid scratches. Amber gemstones are found in Russia, the Baltic, the Dominican Republic and other areas.

Andesine-labradorite (also traded as "andesine", "Congo sunstone", "red feldspar" and "red labradorite") is a relatively new gemstone type that appeared in 2003. It is a color-enhanced variety of labradorite that is not actually andesine, but is a mix of labradorite and andesine (albite and anorthite). Andesine-labradorite gemstones range in color from yellowish to deep red and are typically included. Orange andesine-labradorite gemstones may be amber, pink-orange or honey orange, and can exhibit an attractive metallic schiller.

Calcite is composed of calcium carbonate; the primary ore of calcium. It is similar in composition to pearl and coral, and is also referred to as "limespar" or "calspar". Since calcite lacks hardness, it is mainly a collector's stone. Pure calcite is colorless and when trace impurities are present, it can result in gray, yellow, orange, green, red or blue calcite gemstones, among other colors. Transparent calcite gemstones are most highly valued.

For many years, carnelian was also known as "carbuncle", a term which referred to red garnet originally, but is now applied to any red cabochon gemstone. Carnelian gemstones feature throughout the history of human civilization and are found in several parts of the world.

Citrine gemstones are transparent with a Mohs hardness of 7 and a vitreous luster. Most citrine is mined from Brazil, though it is also found in several other parts of the world. Orange citrine is sometimes traded as "Madeira citrine", due to its rich, Madeira wine-like color.

Jasper is a type of opaque chalcedony that is assigned its own gem group because it has a grainy structure that differs from typical chalcedony. The name "jasper" comes from the Greek for "spotted stone", which refers to its multicolored spots, stripes and other patterns. The variegated appearance of jasper is due to the fact that it is composed of up to twenty percent foreign materials. This is why each jasper gemstone is quite unique. Trade names for jasper include "bumble bee jasper"; which refers to yellow to orange "jasper" from Indonesia that is actually composed of volcanic lava and sediment.

Orange sapphire may be beryllium-treated; a heat treatment that produces stunning orange and reddish-orange stones, which are sometimes traded as "sunset ruby".

Sphalerite is a zinc ore gemstone that has very high dispersion, resulting in incredible "fire" (the separation of visible light into its spectral colors), as well as fiery yellow, orange, red and brown colors. Its resinous to adamantine luster also adds to sphalerite's attraction. Since sphalerite lacks hardness, it is mainly a collector's stone. Due to sphalerite's composition, it is also sometimes traded as "zinc blende". Sphalerite is found in several locations, including Bulgaria, Canada, Spain, the Congo, Namibia, the USA and Zaire, however, gemstone-quality sphalerite is rarely found.

Sphene is a very rare calcium titanium silicate that is also referred to as "titanite" because of its titanium content. The colors of sphene include yellowish-green, green, orange and brown. The remarkably high dispersion of sphene gives it fire that rivals diamond. This means that wonderful flashes of color are seen as sphene is turned in the light. Also its incredibly high refractive index results in fantastic brilliance. An adamantine luster increases the attraction of this rare gemstone even further. Reddish-orange sphene is also known as "greenovite".

The colors of sunstone include pink, red, brown and orange. Sunstone may also be traded as "aventurine feldspar" and can also occur with asterism (the star effect); these star sunstone gems are rare.

Tourmaline is composed of boron silicate and occurs in every color of the rainbow, including peach and orange. One of the fascinating optical effects of orange tourmaline gemstones is their pleochroism; the ability to exhibit different colors depending on the viewing angle. This results in interesting multicolor tourmaline gemstones that may be orange, brown and yellow all in one stone. Orange tourmaline has a Mohs hardness of 7-7.5 and a vitreous luster. Orange tourmaline gemstones may be traded as "dravite" and "tsilaisite".
