It is not every day one can stand a chance to own jewelry that once belonged to royalty. On May 18, Christie’s will give you that opportunity with the sale of exquisite jewels that include several from the collection of H.S.H Gabriela Princess zu Leiningen. The former spouse of the current Aga Khan is letting go of a few memorable and personal pieces that were gifted to her by her second husband (The first being the Prince of Leiningen, hence her title). Before the sale however, the jewels will be on display in Geneva from May 13; the collection is currently making its way to New York as part of a tour.

The Pohl diamond, 36.09 carats

“Sophisticated and classically beautiful, H.S.H Gabriela Princess zu Leiningen’s extensive collection is a true reflection of its owner. A woman of charisma, wisdom, elegance and above all joy” said François Curiel. The Chairman of Christie’s Asia Pacific added “ Each jewel represents a special moment in her life and the happiness she experienced at the time. We are honored to present superb jewels from her collection and extend to all the wonderful karma it brings.”

The Princess Colombian emerald and diamond necklace, by Cartier, the pendant weighing 39.70 carats.

The 46 lots set to go under the hammer in Geneva are estimated to be worth over $15 million. Bidders can expect to see spectacular items from Cartier, Boucheron, Tiffany & Co. and Van Cleef & Arpels. We highlight several key pieces that will certainly excite any avid jewelry collector. The first is the Pohl Diamond. What makes this 36-carat diamond so special is that it was the very first significant diamond that was polished in America (most diamonds are polished in Europe, India or Israel) before it was sold to the Chrysler family in 1943. Having been mined nearly a decade earlier as a 287-carat rough stone, the diamond came into the possession of the princess in 1998 and is now estimated to be worth $3.8 — 5.5 million.

The cultured pearl, diamond and yellow diamond fringe necklace

The next is a creation by Cartier that would make any woman swoon. The diamond and emerald necklace features a 40-carat Colombian emerald. Worth somewhere between $2.5 — 3.5 million, the necklace with the matching earrings was worn at the official dinner that followed the wedding of Prince Felipe of Spain and Letizia Ortiz back in 2004. The other highlight in the collection is the cultured pearl and diamond fringe necklace. Its owner before coming into the possession of the princess was her former husband’s grandmother, Begum Om Habibeh Aga Khan. Upon entering her enviable collection of jewelry, a matching pair of ear pendants and a bangle was commissioned from Van Cleef & Arpels to make a complete parure.

The “Persepolis” necklace

Other pieces that will certainly get your attention, include a suite of emerald, diamond and pearl jewelry from Cartier, an elegant five strand pearl and diamond necklace as well as the “Persepolis” necklace and pair of “Persane” earrings. With graduated emerald bead drops and a larger emerald beat pendant suspended, the suite also features a briolette-cut diamond and oval cabochon emerald surmount. The five strand pearl necklace is made up of nearly 500 natural pearls and daimond roundel spacers.With emeralds, diamonds and sapphires of several cuts, the “Persepolis” neckalce and “Persane” earrings are a set that certainly cannot be missed.

“Aside from their beauty, many of these jewels bare a compelling history of their own” said the Princess. She added “To me they embody wonderful and loving personal memories as well as exciting chapters of my life, full of color, travel and encounters. They have brought me great joy and happiness. Now I wish their journey to continue, bringing joy and happiness to their new owners.”

The sale will be held on May 18, 7pm at the Four Seasons Hotel des Bergues in Geneva. For more information on the auction, visit Christie’s.
