Vintage and Rare Budlong, Docherty, and Armstrong (BDA) 10KT screw backs.

Budlong, Docherty and Armstrong, a jeweler that was in business in Providence Rhode Island from approximately 1850-1971. There are tiny and petite with what they called "the real fake diamond". They advertised DIA-BUD (briefly called DIA-GLO) as the real fake diamond. These earrings are just that. They are really vintage from the 1950's and do need to be cleaned. They is no sign of wear that I can see. They are marked BDA 10KT. They indeed from an era gone by. Reference: Box 5
