This is an original letter written from one masonic lodge to another inviting them to commomerate the birth of St. John. It is both hand written and typed with an original seal from a wax stamp.
I don't have a gram weight on these, but they measure approx 3/4" across, and have a bit of heft. Maybe 5-6 grams or so? They're in very good condition. I've seen pics of other Tiffany Schlumberger sea-motif pieces in the "Jewels of Tiffany" book, including largr pieces with the exact same clam shell design, and same signature style, so I am fairly confident these are real. They are marked 18K as well. However, I can't find any similar pieces online I could comparitively appraise against, and I'm certainly no fine jewelry expert by any means.
