Ok, I don't want to get jumped on here, but I've been talking to distributors, (not mentioning any names) and I was told that there's little or no difference in Vintage Coticule vs the New Coticles being quarried today.
I've seen posts on other forums talking about Garnet content being higher on the vintage stones.
I've never seen anything concrete to prove that. I could be wrong, and if someone can tell me different please do.

Considering the fact that these stones are 400,000,000 years old, what difference would 100 years make. I've read that the best stones have all ready been quarried. I find that hard to believe too.
I can understand that owning an older Coticule may have some intrinsic value, but are they actually better?
