Okay, this is the knowledge that I have in my head:|
Diamonds are made from carbon pushed up really tight so the bits o' carbon form weird bonds and tada, diamond.
Other gemstones form similarly, and impurities give them their colour. So, amethyst is (something? quartz?) with a specific impurity that makes it varying shades of purple. Sapphire is something else, and its impurity makes it blue. Emeralds, rubies- the impurity gives it its colour and how much of it determines how dark.
Based on this information, I can see how a sapphire or emerald or whatever could be made in a lab- get the base material and the proper impurity together, squeeze, done.
HOWEVER! apparently this information is wrong somewhere, because this flyer for some jewelry store advertises lab-made *pink* sapphires. and by what I've been told, that's not possible, because the impurity that makes it defined as a sapphire also makes it blue.
And then there are blue diamonds, different colours of aquamarine and such...
So: What's wrong with my information?
Or are they(specifically the pink sapphire people) full of shit?
Or is it some of both?
