Vintage Maltese Cross Brooch DeNicole

Stylish rare "Maltese Cross" with multicolored glass made using Pate-de-Verre technology (French.- glass paste).
With this technology, multi-colored glass, ground to a powder state, is mixed with special binders and melts at high temperatures until a transparent paste of beautiful saturated colors is obtained..
The brooch is marked with PAT. PEND. There is no company marking, but most likely the brooch is made by DeNicola.
Size 3,5 cm x 3,5 cm.
The condition is good (in the photo it is not a crack, but irregularities in the glass filling).
