You're Opal: The Artist
The Artist · Creative, changeable and full of unexpected color.

You are opal, a stone that is technically not a crystal at all: it is hardened silica gel, packed with microscopic spheres that scatter light into flashes of every color. No two opals look alike, and no two days with you are the same. You are the creative one, the one who sees possibilities in a blank wall.
You feel things vividly and you express them, whether through art, cooking, music or the way you arrange a room. Opal contains water and reacts to its environment, and so do you: you light up around the right people and go dull in the wrong ones. You are more sensitive than you let on, and more resilient than anyone gives you credit for.

How to tell real Opal at a glance
- Color: White, Black, Fire, Blue, Pink. Look at a clean, dry surface in daylight. Color zoning, banding or spots are as diagnostic as the hue.
- Luster: Vitreous. Fresh surfaces shine like glass; a dull surface usually means weathering, so chip or wet a corner.
- Transparency: Translucent. Hold a thin edge up to a bright light and note whether light passes through.
- Mohs hardness: 5.5. It is about as hard as window glass: a knife barely marks it, while a steel file (Mohs 6.5) will.
