Camphor glass is usually a reference to 1920’s jewelry. Hydrofluoric acid gives this clear glass a frosted whitish appearance. A star pattern was often caste on the reverse side of jewelry to give it a radiant appearance. It was popular from the mid-nineteenth century through the 1930’s.
A simple type of earring during the late 1800s into the 1900s was needed to work with high collars on dresses and blouses. We see the stud earring gaining favor at this time. Interestingly, pierced ears fell out of vogue around this time so screw backs then clips had a mid century 1900 surge in popularity. This style is generally hard to date since the ball style has had an enduring popular trend.
The style dates to late 18th century and was very popular during the Georgian era defined as the period between 1714 and 1837. The jewelry of this time has an opulent and regal flair.

There are a few things to look for before: 1) look for hallmarks located on the back of a clasp, inside of a ring or bracelet or on the post of an earring. All fine jewelry should have some type of hallmark. 2) check the weight because fake chains feels fake and solid gold jewelry, for example, is very smooth and heavy. 3) Inspect the prongs since fine jewelry is not glued into the setting but finely crafted in an intricate bezel or prong setting with the exception of pearls. more
