This piece of cut glass is believed to be American Brilliant Period Hawkes Strawberry Diamond with Fan Pattern, but it's not marked, so I can't be sure. The sterling silver top is made by S. Cottle. It could have been used as a dresser jar, vanity jar, powder jar, etc. It has a 4" diameter and is 2 1/2" tall. It has small amounts of damage, as would be expected for something this old. I took pictures and circled it in the images, but it's hard to see. Message me with any questions you have!
