KARATIUM PINK

Abstract

A jewelry alloy that is approximately a 10% or 2.4 karat alloy that has similar color huge and shine and characteristics of 10 karat gold and higher. This alloy is considerably less expensive than traditional 10 karat gold and higher, but has all the similar working characteristics as working in sterling or 10 karat gold metal alloys. The alloy has the following compositions by weight; Gold 5.00-20.00%, Silver 35.00-55.00%, Copper 40.00-60.00%. In addition to its nice pink color and low cost it provides retailers with an affordable alloy for jewelry and provides jewelry craftsmen a low cost pink alloy that responds well to the jewelry manufacturing process (e.g., casting, milling, soldering, tooling, stone setting, polishing and plating).

Description

BACKGROUND OF INVENTION

Even before the recent increase in the price of precious metals in this estranged economy I found an artistic purpose to develop new colored alloys that would be wearable and easy to work in. Then in 2006 I began developing a (pink) silver colored metal while blending different percentages of elements I came up with this pink color alloy. After many tests I found that I could not have this pink color and still stay fairly tarnish and skin discoloration resistant without this small percent of pure gold in the alloy. I believe that you cannot find any other alloy blend with this high of copper content for therapeutic use and so wearable without skin discoloration that traditional copper jewelry presents. Continuing tests of this new alloy proved very positive to casting, fabricating and polishing as used in the jewelry industry. As designer of this new alloy I felt it mandatory that any new well priced alloy have the same characteristics as traditional sterling silver and 14 karat gold, this to enable any craftsmen to start working in this alloy immediately. After the final development of this new alloy I made contact with the Jewelers Vigilance Committee and learned that because this metal is less than 10 karat and has less than 900 fine silver I could not use the word gold or silver in correspondence to any name for this alloy. Hence the name Karatium Pink that is a made up name that I have trademarked. Karatium actually comes in 2 additional colors Yellow and White, and a Sterling version which I have also submitted for patent application

Current status; patent provision filing date Jan. 14, 2008 application No. 61/010,953

The word “KARATIUM” is trademarked with US PTO (77396233) issue date Sep. 23, 2008.
