specimen number:
2062686

location:
Malad Quarry, Mumbai, Salsette Island, Konkan, Maharashtra, India

description:
A cluster of light green spherical shaped crystal groupings of gyrolite to 1.2 cm in diameter, this hosting a pseudo-cubic crystal of colorless fluorapophyllite. In good condition. Classic material for the species and locality.

The Malad quarries, historically active across the Malad and Kandivali areas of Salsette Island, became prominent during the rapid urban expansion of Mumbai in the late 19th and early 20th centuries, supplying stone extensively between roughly 1860 and 1930 before operations gradually wound down. Geologically, the area is characterized by volcanic formations composed primarily of yellowish-brown trachyte rock, popularly known as Malad stone, which was heavily utilized for the facades of many iconic neo-Gothic and heritage monuments across the city.
