You are bidding on a rare mineral specimen of Purperite from the Crystal Mountain District, Larimer County, Colorado. It is a manganese phosphate and gets it's name from it's color. Purpurite forms a series with the mineral heterosite . Purpurite is the manganese rich end member and heterosite is the iron rich end member. Purpurite is a very rare mineral that would get much attention in the semi-precious stone market due to its striking color, if it were not for this rarity. Purpurite is an alteration product of an equally rare mineral called lithiophyllite , LiMnPO4. The alteration takes place atom by atom and actually forms what is called a pseudomorph or "false shape". A pseudomorph is a mineral that has the shape of one mineral but has a different chemistry and/or structure. The alteration is an oxidation reaction with the manganese ion going from a positive two (+2) charge in lithiophyllite to an ion with a positive three (+3) charge in purpurite. With the change in charge in the manganese ion, the lithium ion is then lost. Often some of the original lithiophyllite is still present in most purpurite specimens. The purple color of purpurite is truly unique in the mineral rainbow. It measures 2 x 2 3/8 x 1 1/4 inches and weighs 3.8 ounces. This will make a great addition to your collection. The shipping to US addresses is $2.19. (Postage 1.81, padded mailer .20, delivery confirmation .18) Thanks for looking.
