Comment: Crystal-opal with bright sunny body hue, visibly colored but below the level considered to define 'fire opal'. In our images, close-ups and under the lens, but not with the unaided eye, one may perceive minute seed-shaped light-brown spots; inclusions which on the first viewing (under lens) seem surface based but are really running throughout the flat body. The play-of-color moves in vertical (or horizontal) stripes along the gem, therefore also called 'ribbon opal'. The play includes all rainbow colors, though the purple-blue section is less represented than green-orange-yellow-red. Thoughnot strictly symmetric in shape, it is not a wild free form either, but appears to be a normal U-shape for the casual observer. With only four carats to pay for, it offers 15x12mm to marvel at, the size of an especially big white bean. This, and the vivid color play, assures visibility in a pendant. Too big for a ladies' ring, though. The accompanying DSEF report mentions the water-dependency of all opals, but, as explained elsewhere, opal jewelry needs no regular spa-visits or watering unless it is exposed to radical heating or drying, which, even if the owner would not survive it, would be reversible in the gem (but not in the owner). However, it is true, opals are a sensitive bunch all-in-all, they do need protection from the extreme elements, baseball bats or fake news, though, again, if you survive, the opal will, too. While you must drink water, opal takes its water from the air. Comes with all WildFish perks (lab reports, rainforest protection, grading papers, free shipping, and others).
