Learn About SIlver

Silver was once thought more precious than gold. It is referred to as the metal of the moon and some believe it has powers over emotions, the psychic mind, love, and healing.

This is a very soft metal, so it is often mixed with an alloy like copper. Sterling silver originally was created in an area in Germany called Easter ling. So that’s where the word sterling came from. To be sterling silver, the metal is made up of 92.5 percent silver and 7.5 percent copper.

Pure silver, aka Fine Silver (.999), will melt at 1761 degrees F (961 degrees C), while sterling melts at 1434 degrees F (779 degrees C) and the flow point is 1655 degrees F (902 degrees C).

Coin silver melts at a slightly lower temperature than sterling because it has more copper alloy in it; usually anywhere for 10 to 20 percent of it is an alloy.

Learn About Gold

Yellow gold jewelry has been around for thousands of years and is the oldest known precious metal used in jewelry making. It has a very warm and elegant look and feel to it, especially when placed on the skin. Yellow gold is timeless and is a very appropriate gift when celebrating life's most important occasions.

Yellow gold is the easiest and most practical precious metal to repair or maintain. Re-sizing and re-finishing is inexpensive and almost all jewelers are proficient at yellow gold repairs. Extensive repairs can be done relatively easy without the fear of damaging valuable gemstones and diamonds because yellow gold has a very low melting point.

Pure gold jewelry is made in 24K gold and is much too impractical for everyday wear because of its softness. In order to harden the metal and increase it's durability yellow gold jewelry is mixed with metal alloys like copper or gold. Most gold jewelry in the United States is mixed with alloys that bring the karat grade down to 10K, 14K, or 18K gold. The FTC (Federal Trade Commission) requires all jewelry sold to be stamped with the gold content used by the jewelry maker. To determine the exact gold content examine the jewelry for the 10K, 14K or 18K stamp, if the jewelry is not properly stamped you should be very careful before making a purchase. You may also notice that the jewelry is stamped with .417, .585, or .750, which is the percentage of pure gold.

Learn About Titanium

Titanium is a chemical element with the symbol Ti and atomic number 22. Sometimes called the "space age metal”, it has a low density and is a strong, lustrous, corrosion-resistant (including sea water, aqua regain and chlorine) transition metal with a silver color.

A metallic element, titanium is recognized for its high strength-to-weight ratio.

It is a strong metal with low density that is quite ductile (especially in an oxygen-free environment), lustrous, and metallic-white in color.

The relatively high melting point (more than 1,650 °C or 3,000 °F) makes it useful as a refractory metal. It is paramagnetic and has fairly low electrical and thermal conductivity.

Because it is biocompatible (non-toxic and is not rejected by the body), titanium is used in a gamut of medical applications including surgical implements and implants.

Coloring titanium for its purely decorative effect is one of those processes that ignores the conventional aims, thinking, and criteria of industrial practiced and substitutes aims that are purely subjective and creative. Coloring titanium is possible because its surface, when properly prepared, is highly reactive upon exposure to certain conditions, and forms a series of colors due to the development of a tenacious oxide film. Decidedly decorative in appeal, this oxide film is highly resistant to a wide variety of corrosive substances that would affect other metals. Colors are permanent if unbranded, and if the oxide film is thick enough, will not fade or tarnish.

Two for coloring titanium are possible: coloring by the use of heat, which is more difficult to control and coloring by electrochemistry which with proper controls allows exact, predictable color results.
