Unusual specimen of Mottramite that is either covering Quartz crystals or pseudomorphed after Quartz crystals. There is Quartz at the base of the specimen, but when I look closely at the bottoms of the crystals at the edge, I can see no Quartz in the cores, which leads me to believe the Quartz has been pseudomorphed to Mottramite.

Lazulite, Siderite, Apatite Lazulite, Siderite, Apatite Lazulite, Siderite, Apatite Lazulite, Siderite, Apatite

Large flat specimen of ironstone loaded with crystals of blue Lazulite, tan Siderite, and white Apatite. Most specimens from this locality (which is now closed) only have crystals of Lazulite and Siderite which make them darker in appearance. The numerous white Apatites lighten up this specimen, along with the well dispersed, isolated Lazulites. This was far and away the very best of a large lot of Lazulite  specimens I obtained during a trip to Canada 25 years ago. Colorful, high quality specimen, especially for such large size.
