I don't know much about the Albanian royal jewels so I did some searching in honor of the wedding tomorrow. Most if not all of the women seemed to have owned a tiara featuring a ram, which was the symbol of Skanderbeg, a medieval Albanian ruler. The two eldest sister's of King Zog lived relatively private lives while the youngest four had official court duties. He became King of Albania in 1928, married Geraldine in 1938, and went into exile in 1939.
The women of the Albanian royal family were Queen Geraldine, wife of King Zog Crown Princess Susan, daughter-in-law of King Zog Princess Adile, sister of King Zog Princess Nafije, sister of King Zog Princess Senije, sister of King Zog Princess Myzejen/Myzeyen, sister of King Zog Princess Ruhije, sister of King Zog Princess Maxhide, sister of King Zog

The jewels were exhibited in New York in 1959 before being sold by Ostier, Inc. Marianne Ostier made many of the jewels for the Albanian royal family.
From Christie's press release talking about their Magnificent Jewels auction in October 2004. "Formerly from the collection of Her Majesty, Queen Geraldine of Albania, is a spectacular Art Deco diamond bracelet (estimate: $80,000-120,000) and diamond double-clip brooch (estimate: $60,000- 80,000) that epitomize the design of the late Art Deco period, with its bold, all-white style. Both jewels were created by the Vienna firm of Marianne Ostier, the official jewelers to the Albanian Royal Court. King Zog, the King of Albania, purchased the magnificent bracelet and the double clip brooch from Ostier in 1938 to present as gifts to his fiancée. Subsequently, she wore the brooch on their wedding day, April 27, 1938. In 1960, Ostier was commissioned by the King and Queen to sell these pieces, along with others from her personal collection, to aid Albanian refugees fleeing from their homeland. They have remained in a private collection ever since."
The oak leaf tiara. I can't decide if the younger four sisters all have the exact same tiara or if they have four different but almost the same tiaras. Anyway, according to Ursula the tiara(s) are platinum and diamonds and made by Marianne Ostier. One of them was sold in Spain in 1985 by Duran Madrid.
