Before buying a real (not costume) piece of jewelry at an antique store, investigate the seller. What are their online reviews like? Do they have any paperwork to go with the piece? Ask about the refund policy ahead of the purchase.
Check the maker’s mark (a sign of authenticity)and see if there are other indications as to what type of metal the jewelry is made from. Check the prongs, look at the back of the piece, examine stones, looking for chips and cracks. If it is a real pearl, the shiny pearl exterior can’t be rubbed off. For a safe place to store jewelry, make this jewelry cabinet.
When you examine a stained-glass piece look for chips, cracks and loose glass. Also, check the leading between the glass to make sure there are sharp, clean lines. If you’re lucky, you might find a gem, like this Tiffany lamp! Have you every wondered how to drill a hole in glass? Check this out!
