Formed in 1877, this quarry created Roger Williams' grave stone in Providence. In 1891, 20 men were employed by the quarry.

Gosse (1962) reports:
...magnificent gem quality specimens of sagenitic quartz, sometimes called Thetis' hairstone, were obtained in quantity during the operation of granite quarries there many years ago. Clear, colorless, and smoky quartz was found penetrated by numerous needle-like crystals of black hornblende arranged in haphazard patters which made curious cabochons. Digging in the dumps of these now abandoned quarries will sometimes turn up a crystal of this prized gem material.


Rocks & Min.: 20:464:
