This is a series of  Kiddush cups that is called "24 bridal decorations".
This is a concept from the sources concerning Shabbat.
The series consists of 24 models, each model consists of a different shape, color and composition and semiprecious stone that decorates the rim of the cup. 
These cups function as jewels not only as cups. Jewels for the table, jewels for Shabbat.
The models are limited edition, each one of the 24 models is limited to 18 pieces.
