What is gold-filled?
While the appeal of gold is universal and timeless, adding solid karat gold to your line can require a large investment. Gold-filled metals allow you to incorporate the classic look of yellow and rose gold into your jewelry while keeping your designs affordable.
More valuable and durable than gold-plated materials, gold-filled contains a layer of karat gold. Since the price is more accessible than solid karat gold, gold-filled is ideal for creating high-end fashion jewelry or experimenting with new designs
Rosarita is a unique material, which derives its exceptionally rich, red color from the process of gold refining. It is a unique by-product of the 1960s and 1970s gold refining processes. Alaskan beach sand was smelted for its gold content and the slag by-product was Rosarita, which is essentially a gold-infused glass. The base material for Rosarita is silica (which is quartz particles) mixed with gold at high temperatures. Old processes prior to 1960 used the old method of open crucible and fire (infused heat) to smelt the sand, leaving behind a glassy-like material in the crucible, which is known as slag. This gold slag was used in the 1940s through 1970s for jewelry, carvings, flint napping, etc. This material known as Rosarita is some of the most exceptional colored gold slag ever produced. Most other slag were mostly red in color but not nearly as vivid as the magnificent Rosarita.
Rosarita is no longer produced because of improved efficiency in gold refinement. Modern processes extract nearly all of the gold out of the sand, leaving an un-remarkable clear glass slag without the deep red color that makes Rosarita so beautiful
