Phosphates.

Apatite ↗

Mineral group / trade name

Apatite can be blue, green, yellow and many other colors. Its bright jewelry colors are appealing, but its lower scratch hardness makes thoughtful settings particularly useful.

Turquoise ↗

Mineral species

Turquoise brings blue to green color to cabochons, beads and inlay. Dark matrix patterns can be part of its appearance, while treatment and porosity matter just as much as color when choosing and caring for a piece.

Wavellite ↗

Mineral species

Wavellite often forms radiating groups of fine crystals, sometimes rounded like tiny green fans. A small specimen can reveal more structure than a large polished object.

Variscite ↗

Mineral species

Variscite is a hydrated aluminum phosphate often encountered in green nodules and polished cabochons. Cream or brown host areas can add a contrasting pattern.

Purpurite ↗

Mineral species

Purpurite can have a striking violet-to-purple appearance on natural surfaces. Its soft, sometimes earthy texture is part of the material’s handling story.
