Ulexite : NaCa[B₅O₆(OH)₆] · 5H₂O
	U.S. Borax Open Pit, U.S. Borax Mine (Pacific West Coast Borax Mine; Pacific Coast Borax Co. Mine; Boron Mine; U.S. Borax and Chemical Corp. Mine; Kramer Mine; Baker Mine), Kramer Borate deposit, Boron, Kramer District, Kern Co., California, USA Satin-like compact crystalline block of colorless ulexite crystals. Ulexite crystals have fiber optic properties, transmitting light from one end to the other. Very clean, natural specimen. Overall size of mineral specimen: 5.5x3x2 cm. Size of individual crystals: 5.5 cm.

Ulexite : NaCa[B₅O₆(OH)₆] · 5H₂O, Calcite : CaCO₃
	U.S. Borax Open Pit, U.S. Borax Mine (Pacific West Coast Borax Mine; Pacific Coast Borax Co. Mine; Boron Mine; U.S. Borax and Chemical Corp. Mine; Kramer Mine; Baker Mine), Kramer Borate deposit, Boron, Kramer District, Kern Co., California, USA White Ulexite with amber colored Calcite. This form of Ulexite is known as TV rock because when you cut sections of the Ulexite perpendicular to the length of the parallel acicular Ulexite crystals that form this material, the resulting blocks of material are quite transparent and transmit light easily. An image placed on one surface of these ...

Ulexite : NaCa[B₅O₆(OH)₆] · 5H₂O
	U.S. Borax Open Pit, U.S. Borax Mine (Pacific West Coast Borax Mine; Pacific Coast Borax Co. Mine; Boron Mine; U.S. Borax and Chemical Corp. Mine; Kramer Mine; Baker Mine), Kramer Borate deposit, Boron, Kramer District, Kern Co., California, USA Ulexite. R. Currier collection. This variety of of Ulexite is called clam shell Ulexite because it resembles a clam shell. In certain horizons near the top of the borate deposit at Boron, they are abundant, and hundreds of them have been collected and distributed to collectors. Scale at bottom of image is an inch with a rule at one cm.

Ulexite : NaCa[B₅O₆(OH)₆] · 5H₂O
	U.S. Borax Open Pit, U.S. Borax Mine (Pacific West Coast Borax Mine; Pacific Coast Borax Co. Mine; Boron Mine; U.S. Borax and Chemical Corp. Mine; Kramer Mine; Baker Mine), Kramer Borate deposit, Boron, Kramer District, Kern Co., California, USA Ulexite. A knobby mass of intergrown fibrous micro crystals. Countless tons of this material have been mined at Boron, and placed on the borate dumps for long term storage. Few collectors ever collected this material and had the patience to clean the mud off the specimens. Scale at bottom of image is an inch with a rule at one cm.
