Opal-AN (Hyalite Opal) with minor "Blood Vessel Opal"

Item Description

These some of the most interesting and certainly unique specimens of Opal from any contemporary locality. This specimen is from a recent discovery (January 2019) at a new mine in San Luis Potosi. We were happy to get these pieces from a good friend who has been mining this material exclusively for the past few years. This small cabinet features a layer of "bubbly", GEM quality to translucent, colorless and soft blue colored "balls" of Hyalite with minor matrix. One edge of the piece features some tiny inclusions of reddish to orange colored iron oxide that resemble thin organic "capillaries" or "blood vessels", from which the nickname "Blood Vessel Opal" was given to this material. It's truly unique for Opal and really gives the piece character. Like a lot Hyalite specimens, this piece shows a brilliant green fluorescence under SW UV light. These specimens are incredibly limited, and you honestly can't find anything like on the market. A great piece for anybody who collects Mexican minerals, worldwide Opals or fluorescent minerals. A wonderful specimen of this beautiful Opal variety. Weight on the specimen is 42.10 grams. It should be noted that the term "Hyalite" Opal is no longer valid, and the material is now called Opal-AN.
