This listing is for an antique pair of pince nez eyeglasses with ear hook and hard case.  The bridge is marked Consol.  There doesn't appear to be any other markings on the glasses.  The eyeglasses weigh about 14.11 grams.

The ear hook and the nose bridge were both tested for gold content.  Both areas of the glasses tested positive as 10K gold.  10K and 14K acid were used in the test, as shown in the photos.  The gold scratch lines in the middle and the left are from the eyeglasses.  The scratch line on the right is from a non-gold brooch that is not included in this listing.  There may be some metallic components such as screws that are not gold.

The glasses have some wear but are structurally sound.  Please see photos and feel free to ask questions.
