How to Identify Topaz
Topaz is hardness 8 — it scratches quartz — with glassy prismatic crystals showing striations along their length and one perfect flat cleavage across the base. It feels heavier than quartz of the same size. Colors run sherry-amber, blue, and clear; sun exposure fades some sherry topaz, so shade fresh finds.
