Did you know there is a type of stone called "Druzy"? I'm not making this up, it's an actual thing. Here's a description of how it is formed from the Kaelin Designs website:
"Druzy stones [...] are the result of a stone
cooling more quickly on the outside than the inside when it is formed
from its near molten state. Nearly every stone that exists has the
potential to have a small section of "druse", or "druzy" in its
matrix. Many druzy stones are naturally colored due to the inherent
qualities of the stone [...]. Occasionally, however, the stone in question, while
having excellent druzy crystal structure, lacks the beautiful colors
that appeal to many people. In this case, a stone artisan will take the
cabochon and a piece of metal such as titanium, gold, or platinum and
vaporize the metal which will permanently deposit itself onto the
surface of the stone. When using a metal like titanium, the stone artist
can control the resulting coloration by the type and amperage of
electrical current he uses to vaporize the metal. Some of the variations
possible in titanium include blue, purple, gold, green, and every
combination in between."
All of which makes for something quite pretty:
Can you imagine the conversation? "What's that stone?" "It's a Druzy." "Yes it is, but what type of stone is it?" Hours of entertainment.
