Sr2B11O16(OH)5 · H2O
Colour:
Colourless, white
Lustre:
Vitreous, Silky, Pearly
Hardness:
2
Specific Gravity:
2.58 - 2.69

Monoclinic
Name:
Named in honor of John Allen Veatch (5 March 1808, Knox County, Kentucky, USA - 24 April 1870, Portland, Texas, USA), surgeon, surveyor, and scientist. He was the first person to detect boron in the mineral waters of California in 1856.
The three known polytypes of veatchite (1A, 1M, 2M) are described by Grice & Pring (2012).
The SrCa-ordered analogue is called calcioveatchite.
The SrCa-ordered analogue is called calcioveatchite.
