This is an extraordinary Antonio Pineda Gladiator Cuff with black onyx stones. The spikes are half an inch tall and are well rounded not sharp. This bracelet has a 2 in. diameter and rounds the wrist superbly with comfort. The design is outstanding, striking and the degree of difficulty to produce is high taking great skill. A Mexican Silver treasure weighing 112 grams and with a height of 1.75in. There are reflections in all of my pictures since the spikes are really all over the heavy silver lattice work. There is no damage, dents or flattened ends to the spikes. Absolutely well cared for and properly marked. There are worn letters, eagle and some on the crown. In your hands you can see the marks better with more than enough to verify absolute authenticity. Collector and Museum quality.
