I need help understanding Chalcedony.

0 votes

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.

Respectfully, Almandine

Chalcedony on a technical sense is just the microcrystalline variety of quartz - meaning that it does not form in visible crystals. In the gem market the term chalcedony is generally reserved to describe the light blue variety with a solid color.
