New Price for WigJig Delphi Jewelry Tool:
Starting the First of September, 2011, we have re-priced our WigJig Delphi to sell at a suggested retail price of $19.99. We have never sold any of our clear WigJig tools for a lower price. We believe that the Delphi, at the price of $19.99, is an excellent value. If you have a WigJig Olympus or Olympus Lite and think that you would benefit from a jig that had smaller pegs and a pattern with five holes per inch instead of the four holes per inch in the Olympus family, please consider the purchase of our WigJig Delphi at this new, low price. You can view our WigJig Delphi in our Internet store by selecting here.
Silver Filled Jewelry Wire and Findings:
We have just ordered silver filled wire in 16, 18, 20 and 22 gauge in round, 20 gauge in square and 21 gauge in half-round. This wire should be available for sale during the last week of September.
Birthstone for September: The birthstone for September is the sapphire. For more information on sapphires, please select here. Sapphire is the gemstone quality version of the mineral corundum. Chemically, sapphire is aluminum oxide and is almost identical to a ruby. For this reason the sapphire and the ruby have very similar characteristics. Sapphire can come in almost any color, with the colors being determined by the impurities in the stone. The more red versions of a sapphire are a ruby. With that said, blue is considered the normal color for a sapphire for use in jewelry. The blue color results from titanium and iron inclusions in the crystal. Many naturally occurring, mined sapphires are gray in color. Frequently, these sapphires will have their blue color improved by heating the gemstone for several hours at a temperature of 1,800 degrees centigrade.
Some gemstone quality sapphires exhibit asterism. Asterism is the optical property of displaying a star when illuminated by a single light source. Star sapphires like the 182 carat Star of Bombay Sapphire demonstrate this optical property.
The hardness of a sapphire, like a ruby is 9.0 on the Mohs hardness scale. While this hardness makes the sapphire the second hardest naturally occurring material, the sapphire is still about 1/4 as hard as a diamond. Fortunately, a sapphire is 4 times harder than most glass and sand.
Because of this hardness and the fact that sapphires can be made in a laboratory relatively cheaply, there are several industrial applications for a sapphire. In fact, man-made or lab created sapphires have become relatively commonplace. Sapphire crystals can be grown in a lab up to many inches in size. Clear sapphire is used as watch faces and as optical components. Sapphire wafers are also used in the semiconductor industry as a base for semiconductor components. Sapphires and rubies have both been used in making lasers. Man-made sapphires are also available for use in making jewelry.
