Made of a very durable and chip resistant tempered glass.
These are all original, not reproductions. If you need any more pictures or information, feel free to ask before purchasing. Any flaws are shown in the last pictures. The green saucer has a chip on the inside circle and outside also.
The geometric pattern on the tumbler adds a nice touch to your morning coffee routine.
The saucers are 3 3/4" wide. There is underglaze crazing on the bottom of the saucers as shown in photo 7. All of the jewels are intact and in very good condition.
You can tell this is Tiffany & Co. by the crisp lines and the soft, polished finish.
