Carnelian Agate Crystals from Brazil
Carnelian agate tumbled stones produced from stone mined in Brazil. Exceptionally colourful and highly polished.
These crystals are classed as carnelian agate because they're agate that has been treated to replicate the colour of carnelian.
Carnelian and agate are both varieties of chalcedony. Carnelian tends to be less included hence stones are more translucent. It's also slightly rarer which makes it more expensive.
Agate is a banded chalcedony which is a microcrystalline variety of quartz. Microcrystalline means its crystals are too small to be seen with the naked eye.
In red varieties of agate which includes carnelian the colour is caused by iron oxides.
Our carnelian agate crystals are a medium sized stone. Size can vary from piece to piece.
