Hello Knowledgable Folk,
I just don't understand what makes Chalcedony different from the other "beads". I do know that something makes them more expensive than their counterparts, but what it is, I just don't get it.
What makes it a Chalcedony bead when it looks just like Blue Lace Agate, for instance.
Thank you for your time and trouble if you answer my query.
Please explain: What is Chalcedony.
