Garnets for Capricorns in January

 

 

 

Garnets are a set of closely related minerals that form a group, resulting in gemstones in almost every color. Red garnets have a long history, but modern gem buyers can pick from a rich palette of garnet colors: greens, oranges, pinkish oranges, deeply saturated purplish reds, and even some blues.  Red garnet is one of the most common and widespread of gems, found in metamorphic rocks (which are rocks altered by heat and pressure) on every continent. But not all garnets are as abundant as the red ones. A green garnet, tsavorite, also occurs in metamorphic rocks, but it’s rarer because it needs unusual rock chemistries and special conditions to form.
Demantoid is a rare and famous green garnet, spessartine (also called spessartite) is an orange garnet,                                                                                                    and Rhodolite is a beautiful purple-red garnet. Garnets can even exhibit the color-change phenomenon similar to the rare gemstone alexandrite. 
      All garnets have essentially the same crystal structure, but they vary in chemical  composition.  There are more than twenty garnet categories, called species, but only five are commercially important as gems. Those five are pyrope, almandine (also called almandite), spessartine, grossular (grossularite), and andradite. A sixth, uvarovite, is a green garnet that usually occurs as crystals too small to cut. It’s sometimes set as clusters in jewelry. Many garnets are chemical mixtures of two or more garnet species.

 

 

 

 

 

 

ZIRCON for December

Prized as a talisman since medieval times. zircon was believed to clarify the mind, improve confidence and inspire the spirit. Among its many attributes, zircon was thought to bring wisdom, wealth and protection to those who wear it. Available in several colors including yellow, orange and green, with blue and red most sought after, and brown most available. Brown zircon is commonly enhanced by traditional heating methods to produce red and blue colors, while yellow is occasionally heated to improve its color. Green is not typically enhanced. To clean, use warm soapy water and a soft brush. Avoid contact with chemicals. Ask you jeweler for details regarding enhancement and care.
