Godt at vide

The founding year of 1908 is that of the Gemmological Association of Great Britain, stated on its own site; the shop trades as Gemmological Instruments Ltd from 21 Ely Place, London. It is a reseller as well as an own-brand supplier, so some catalogue lines are other makers' products.
