Form:
Sawtooth aquamarine crystals can vary in form, with some being sharp and well-defined prisms, while others may show etching or jagged edges, reflecting the rugged terrain of the Sawtooth Mountains.
Rarity:
These aquamarine specimens are considered rare, particularly those with both gem quality and intense color saturation, and they are not frequently found on the market.
Locality:
