The easiest way to do so is first to determine the maker by looking for and then researching any markings present on the glassware.

- 1stDibs ExpertOctober 24, 2024To tell if your vintage glasses are gold, look on the nose bridge and the temples for a purity mark. Makers often stamped their solid gold pieces with “12K,” “10K,” “14K” and other markings to identify their gold eyewear. You can research all of these markings using trusted online resources. Should you locate a "GF" mark, it is likely that your glasses are gold-filled rather than solid gold. This means that the frames are predominantly a less expensive metal but do have a thin layer of genuine gold alloy as a finish. Another mark that indicates your glasses contain some gold is "RGF." The mark stands for “rolled gold filled.” Glasses bearing this mark feature a gold-plated finish that is thinner than what's found on traditional gold-filled frames. For assistance identifying your eyeglass frame material, consult a certified appraiser or experienced antique dealer. Explore a selection of vintage glasses on 1stDibs.
- 1stDibs ExpertNovember 2, 2023To tell if vintage Cartier glasses are real, first look for the brand's logo on the outside of the arms. It should be spelled correctly and in the French luxury fashion house's iconic gold-toned italic font. Because some vintage pieces may lack serial numbers and other markings used to identify contemporary eyewear, you may wish to enlist the help of a licensed appraiser or knowledgeable dealer for assistance with authentication. Explore a selection of Cartier glasses on 1stDibs.
- 1stDibs ExpertApril 5, 2022The easiest way to tell if a bead is glass or plastic is to feel it. Glass beads will be cooler to the touch, whereas plastic beads will be closer to room temperature and warm up quickly in your hands. Another test you can perform is to listen to the sound. Glass has a distinctive ring since it’s harder whereas plastic is softer and has a duller sound. Shop a range of vintage glass bead pieces on 1stDibs.
