ALL ABOUT

Pyrope gemstones are often very clean and can be totally free of flaws and inclusions. Pyrope Garnets are usually a lighter color and more transparent then the similar Almandine Garnets, and sometimes have a very slight brownish tint. A well-known variety of Pyrope is the rose-red to violet variety, known as Rhodolite, has become a very popular gemstone. Rhodolite is not a pure Pyrope, but an intermediary between Pyrope and Almandine in composition, though closer to Pyrope.

USES

Pyrope is cut into red Garnet gemstones and used in all forms of jewelery, especially rings, earrings, and pendants. It is also polished into cabochons and beads for use in bracelets and necklaces, and may be tumbled into smooth irregular stones for jewelry.

VARIETIES
Color-Change Garnet – Garnet that exhibits a different color in natural and artificial light. Color-Change Garnet is a intermediary mix between the Pyrope and Spessartite (though closer in composition to Pyrope), and presents a color change from a light brownish, yellowish, or greenish in daylight to a pink or purplish color in incandescent light. A few rare specimens may even have a bluish color, which is extremely rare for Garnet.
Rhodolite – Rose-red form of Garnet with a light color or more purplish color than typical Garnet gemstones. It is usually an intermediary variety between Pyrope and Almandine, though more closely towards Pyrope in composition.Garnet gemstones are not enhanced, and their colors are always natural.The original deposits of Pyrope were in Bohemia, in the Czech Republic. These sources are more historical then practical, and little material comes from there today. The main Pyrope deposits are in Mozambique, Tanzania, Kenya, South Africa, India, Sri Lanka, China, and the U.S. (Arizona and North Carolina).Most dark red gemstones on the market are either Pyrope or Almandine Garnets. Almandine and Pyrope Garnets can be very difficult to distinguish from each other, though Pyrope usually has the lighter color of the two, and is also lighter in weight. Spinel and Rubellite Tourmaline can also resemble Pyrope, and Ruby is usually a lighter red color. Quartz is one of the most common and varied minerals on earth, and its abundant colors produce many gemstone types. Amethyst and Citrine are the most popular and valuable gem varieties of Quartz, but other forms also make important gemstones. Chalcedony describes any form of Quartz that is microcrystalline, in compact form without any visible crystals. Chalcedony also has several varieties used as gemstones, most notably Agate, Carnelian, Tiger’s Eye, and Chrysoprase.
