Unsigned which is sometimes characteristic of older pieces of crystal which were unsigned. They were probably produced by Ajka in Hungary which has been making colored crystal for Faberge and now Waterford for many years as they are one of the last remaining companies to produce these type of fabulous pieces. I bought them about 10 years ago or so and they are rare and coveted. Cannot find any on the internet or at retail.
Each piece is 6 3/8 inches high, quite wide at 5 3/4 inches at the top opening and have a starred base, typical. Signature design of Ajka pieces. The stem and base which is approximately 3 3/4 inches are clear crystal. They are magnificent and will adorn a table, display cabinet as shown and you will get lots of compliments on them. Impeccable design on these pieces and the cobalt blue is outstanding.
I use my favorite brand like Varga everyday and Waterford Cobalt dofs, my favorite for drinks. I let my guests pick out their glass and color when my wife and I entertain. No original packaging or boxes.They will be well wrapped and double boxed to arrive for you to enjoy. Hand wash only with mild warm water and liquid dish soap. They may crack when exposed to high heat then cold.
Your responsibility as I cannot register you for their program. You will not be disappointed in these spectacular crystal pieces and very rare.
