Fingerprint Jewelry Charms


Fingerprint Charms are custom made one at a time by hand in the USA. Usually the thumb provides the best fingerprint. a good fingerprint has distinctive lines and definition. Once the fingerprint is received by our fingerprint jewelry designers, a digital version is created. The artist will then focus on the most interesting portion of the print and crop that area of the fingerprint and digitally clean the fingerprints edges for a clean crisp edge. Then the digital fingerprint is transformed by a computer assisted manufacturing device that lets the jeweler create a wax mold of the image. Once the mold is made the jewelery designer uses the old age process of the lost wax casting method to create a personal fingerprint charm. The lost wax jewelry charm process is as follows: The wax mold, called a pattern, is first weighed so the amount of metal required to fill the mold (gold, silver, etc.) can be determined. Then the mold is attached to a base, and a flask is slipped over the base. Once the mold is in the flask, a kind of plaster that looks like pan cake batter called investment, is mixed up, put in a vacuum to get all the air bubbles out of it, and then poured into the flask. It is then left to dry and harden. This takes a minimum of two hours.

Once the investment is dried, the base and flask are removed. Now the piece is put into an oven to burn out the wax. Next a centrifuge is used to force the melted metal into the investment mold. Finally, the piece is cleaned up by filing and polishing the one of a kind fingerprint jewelry.
