What You Should Consider When Looking For Turquoise In Silver Jewelry:

Turquoise is a beautiful gem that is wonderful in silver turquoise jewelry. Scientifically it's a blend of phosphates and aluminum with a small amount of copper oxide, which gives it its blue color, and manganese oxide, calcium, zinc and iron.

The green color comes from the iron or aluminum and yellow is from the zinc.

Green is the most common color for turquoise gemstones, and as a matter of fact blue gemstones very often change to green when exposed to sunlight for a long time.

Different blends of these elements give turquoise its range of colors, with the most valued being those with a deep blue color and yellow colored stones having the lowest value.

High quality gems, for instance Persian turquoise, do not tend to fade and maintain their lovely blue color indefinitely.

Some gems have a main color with colored lines in a spider web pattern marking the surface. This is caused by uneven dispersal of the different elements present in the stone and the marks might be yellow, black or brown in lots of patterns.

However pure colored gems are more sought after than gems with a spider web matrix though turquoise gemstones of intense blue color, even though they have a spider web matrix, are more sought after than yellow or green pure colored gemstones.

Natural gemstones of a pure color, i.e. those which are not marked with spider web matrix, are rare and are very highly prized.
