Inhabitants of Glomel are called glomelois in French.

Glomel is located on the northern slope of the Montagnes Noires (french, Black Mountains). The Minez Du is the highest peak in the village. The village centre is located 6 km (3.7 mi) west of Rostrenen and 53 km (33 mi) north of Lorient.

The geology of Glomel is renowned for its exceptionally rich andalusite deposit, known for having the highest andalusite content in the world. This unique mineral, prized for its high-temperature resistance, has been extracted at the Guerphalès mine since 1970. The site, operated by Imerys, plays a crucial role in the global andalusite market, producing 65,000 tonnes annually, which accounts for 20-25% of global output.^[5][6]
