An outstanding specimen of lazulite with siderite and quartz from the famous phosphate deposits of Yukon. It comes from the collection of Maurizio Sprovieri, Italy with a label and Glen Kisselman collection – no label.

The lazulite crystals are sharp, highly lustrous, very well formed, monoclinic, deep indigo blue color up to 10mm big. The crystals have gemmy areas with marvelous royal blue nuances. Yellow-brown siderite crystals are seen too. Some colorless, transparent and sharp quartz crystals add a strong contrast. It displays attractively on both sides.
