Turquoise Jewelry
Turquoise jewelry makes use of the exquisite turquoise
mineral. It is a hydrous phosphate of the aluminum and copper elements.
The colors of this gem type range from blue to green.
The unique hue of turquoise jewelry has made it a prized decorative
option for thousands of years. It is rare and valuable in its finer
grades. However, today it can be difficult to detect true turquoise.
For that reason, its value has decreased over time.
The value of turquoise jewelry is usually determined by its hardness
as well as the richness of its color. This mineral is very fragile and
sensitive to solvents. Expert care must be taken to not expose it to
perfume or an excess of skin oils. Such materials will dull its color
and attack its finish.
