C Crystals at a Glance

Cacoxenite

Cacoxenite is a golden, brown or reddish iron phosphate mineral that often appears as needle-like inclusions within quartz or amethyst.

It is traditionally associated with:

• Personal growth.
• Wider perspective.
• Learning from change.
• Reconsidering old assumptions.

Similar-looking inclusions may be sold under the same name, so identification can require more than appearance alone.

Calcite

Calcite is a common carbonate mineral that occurs in many colors and crystal forms.

Popular varieties include:

• Orange calcite.
• Blue calcite.
• Green calcite.
• Honey calcite.
• Mangano calcite.
• Optical calcite.

Calcite is commonly associated with clarity, renewal and fresh thinking.

Because it is soft and acid-sensitive, keep it away from harsh cleaners and harder stones that may scratch it. The calcite color guide explains how its traditional symbolism changes across different colors.

Candle Quartz

Candle quartz is a trade name for quartz formations with layered or crusted surfaces resembling melted candle wax.

It is commonly linked with:

• Inner reflection.
• Patience.
