Rare Locality TURQUOISE Specimens (2) - - Llanada Mine, California - - Collected 10 - 73
Item History & Price
| Reference Number: Avaluer:20461811 |
I'm pleased to offer this rare locality specimen of Turquoise with Riebeckite from the Llanada copper mine, Llanada, San Benito County, California. The specimens measure 1.81 x 1.22 x .84 inches or 4.59 x 3.09 x 2.13cm (#1066) and 1.52 x .77 x .54 inches or 3.85 x 1.97 x 1.36cm (#1065) and is from the David W. Reynolds collection of San Jose, California. His collection catalog indicates that he collected these in October, 1973.
I don't think that there was any copper p...roduction at the Llanada mine---I can find no references to any production numbers. This mine is best known for its turquoise and nissonite (the Llanada mine is the type locality) specimens---still, the mine is no doubt virtually unknown except for California collectors and specialists and perhaps micromount species collectors. Both pieces show turquoise with dark riebeckite and an unknown blue mineral that may be chrysocolla or nissonite---it is not turquoise. The turquoise has that typical porcelaneous look while some of the unknown blue looks somewhat radiating to fibrous under magnification. And riebeckite is believed to be the dark mineral owing to the size of some of the rough crystals on the larger piece. Mindat.org does not list riebeckite but rather glaucophane but the classic Handbook of Mineralogy mentions the association as riebeckite.
Please check my feedback and my other items. All specimens are carefully wrapped, come with complete and accurate labels and are quickly shipped. As always, your complete satisfaction is unconditionally guaranteed and I even offer FREE return shipping on any item that fails to satisfy for any reason---you can't go wrong. I'm reminded of the firm pledge printed on the old Foote Mineral Company mineral catalogs from more than a century ago,
"Quality of specimens is assured as we permit return of specimens at our expense."
Thanks for looking!
