Gems and Minerals Mined on Mt. Antero
Aquamarine, a light blue stone, gets its name from the Latin word aqua, meaning water, and marina, meaning the sea.
Aquamarine is often light in tone and ranges from greenish-blue to blue-green. The color tends to be more intense in larger stones, while darker blue stones are typically more valuable. It grows in large, six-sided crystals that can be up to a foot long, making it a great gem to cut and polish into larger carats. Aquamarine is Colorado’s state gem, March's birthstone, and used to celebrate 19th wedding anniversaries.
Blue & Clear Topaz
Blue topaz is one of the most popular stones in the world. It's a hard, beautiful gem available in a wide range of hues. While it's a very hard stone, it's not the most durable. That's because it has perfect cleavage, a property it shares with diamonds. This means it can be chipped or split by a sharp blow.
Blue topaz is rare and tends to be a very pale blue. The vivid blues available on the market have all been produced by the treatment and enhancement of colorless white topaz.
Phenakite is a rare gem that appears pale blue or yellow when it comes out of the ground but turns clear when exposed to light. It looks like quartz, though it’s harder than quartz. To many, a well-faceted phenakite can look like a diamond. Because of its rarity, phenakite remains a collector’s gemstone.
Smokey quartz ranges from a light yellowish-brown to a brown that is so dark, it appears black. When cut as a gem, the preferred colors tend to be orange-brown and red-brown.
Smoky quartz is a less expensive gem because it’s found in many locations and its brown color is not currently in high demand. It is often found in large crystals of excellent transparency with few inclusions.
Purple and Blue Fluorite
Fluorite is one of the most collectible and highly sought-after crystals in the world. It is well-known and prized for its glassy luster and comes in a spectrum of colors. Purple, however, is by far fluorite's most famous and popular color, easily competing with the beautiful purple of amethyst.
Morganite is the pretty, peachy-pink variety of beryl, cousin to the more familiar beryls, like emerald and aquamarine. Morganite's beautiful, feminine colors are a result of the presence of manganese.
Named in honor of financier and gem enthusiast J. P. Morgan, morganite has many redeeming qualities, including durability, luster, clarity, and brilliance.
Golden Beryl is a gem that comes in a sunny yellow color. Because golden beryl is largely unknown, it is much more affordable than aquamarine. Golden beryl gemstones are an excellent choice for jewelry because they are hard, tough, and resistant to corrosive substances. Gemstone lovers are beginning to discover this fine gem, and as a result, golden beryl is becoming increasingly popular for jewelry.
