Part of September 2025 Discovery Auction (timed auction by Alaska Premier Auctions & Appraisals)

High bid $120.00

Status: Sold

A natural Welo opal specimen weighing approximately 12.95 carats, displaying attractive green and red play-of-color. Welo opals are formed through the interaction of water and silica-rich volcanic rocks, typically originating within nodules and seams of basaltic deposits in Ethiopia—contrasting with many other opals that develop in sedimentary environments. This example shows lively color and natural form, appealing both as a collector’s specimen and for potential custom jewelry use.
