Item Description

This is a nice old-time specimen of the classic crystals of Gadolinite-(Y) from the famous locality at Frikstad, Norway. Some of the best examples of this uncommon yttrium iron beryllium silicate are found in this area. There are many quarries at Frikstad, and it's hard to say specifically where this piece was found. This pegmatite locality dates back many decades, and most specimens were mined long ago. This piece is a fairly good sized (for the species and the locality), sharp, well-formed, dark black-brown colored crystal of Gadolinite-(Y), free of matrix. There are some contacted edges, so the piece is not 100% undamaged, but it's still a nice representation of these hard to find piece. You rarely see these impressive and well-known specimens on the market, and if you collect rare-earth minerals, this would be a nice addition to your collection. An interesting side note: Yttrium is a significant component of this mineral, and the mineral was named after J. Gadolin, who actually discovered yttrium. From the collection of Shields Flynn.
