How is quartz color treated?

How does quenching change the color of quartz?
The quenching produces tiny cracks within the quartz which serve as conduits for the entry of dye. The cracks allow the dye to penetrate deep into the stone. The result is a transparent colored stone with bright internal reflections produced by the interaction of light with the tiny fractures.
How do you dye quench crackled quartz?
Place the hot quartz in the bucket of dye. The water will instantly cool the stone, causing cracks to form on the surface, which will then soak up the dye. Quench crackled stone isn't uniformly colored; it has a crackly appearance, hence the name.

What causes quartz to be blue?
The blue color has been attributed to three basic causes: the partial reflection of light from inclusions, the scattering of light by closely spaced microfractures in the quartz, and the occur- rence of scattered titanium as a coloring agent. Each of these factors can produce a blue color in quartz.
How do crystals get their Colour?

How to tell if a stone is undyed?
Shallow Penetration: The dye is always applied after the stones have been tumbled and polished. This is because most dyes are only able to penetrate a short distance into the stone. This gives dyed stones a brightly colored surface without deep penetration. If these stones are scratched, chipped or scraped, an undyed interior is usually revealed. You can also break a stone, scratch through its surface or touch it against a grinding wheel to see if the interior is undyed.
