Austro-Hungarian silver bracelet

This magnificent bracelet was made in the 19th century, presumably between 1870-1890 on the territory of Austria-Hungary. The bracelet is marked on a hidden clasp, but I can not decipher the marking. There are 3 characters and the middle character "P". Jewelry Austro-Hungarian masters most revered and wanted by collectors around the world. The bracelet is made of silver with gold, which has brightened for more than 130 years and covered with a noble patina. The bracelet has more than 50 stones and weighs 30 grams. The large Central stone is a large amethyst (?) is set with an open back to allow light, it glows brightly. The other stones are set with closed backs, showing the depth of the purple tone,and only two tiny stones are missing. Otherwise, this wonderful bracelet is in excellent condition. It is an authentic rarity and a beautiful addition to any collection of vintage jewelry.
