Aron S. Gordon (1911-2001), was a native of Houston.
Aron Gordon attended the University of Texas and later worked for the family business,
Gordon's Jewelers, founded by his father in 1905.

During World War II, he joined the United States Navy and was stationed in Pearl Harbor
where he served as an officer on the staff of Admiral Chester Nimitz.

After the war, he returned home to resume his position in the family business.

In 1989, when the company was sold, Aron Gordon was Co-Chairman of the Board.
By that time, the Gordon Jewelry Corporation, with over 600 stores,
had become the second largest retail jeweler in the country,
and was listed on the New York Stock Exchange.

Aron Gordon and his wife Anaruth were avid collectors
and traveled extensively from the late 1940s to 1989.

They both served on the Board of Trustees of The Museum of Fine Arts in Houston.
In addition, Aron Gordon served on many boards as Director or Trustee,

The Hixon Ruby Crystal


The Hixon Ruby Crystal is a 196.10-carat gem.
It was donated to the Natural History Museum of Los Angeles in 1978 by Frederick C. Hixon.
It is considered to be one of the most perfect large ruby crystals in the world.


The Logan Sapphire Brooch


Historically the finest sapphire gems came from Sri Lanka and Burma,
and the same is pretty much true today.

Sri Lanka, nicknamed the "Gem Island," has been an important source of sapphires, rubies,
and other gemstones for more than two thousand years.

The stones that have been eroded from Sri Lanka's central mountains are still plucked
by hand from gravel deposits that cover most of the southern half of the island.

Sapphires from Sri Lanka are typically light to medium blue,
and gemstones have been cut that weigh up to several hundred carats.

The National Gem Collection boasts one of the largest fine blue sapphire gems,
including the 422.99-carat Logan Sapphire from Sri Lanka.


The Logan Sapphire's fine blue color really shows in this photo of it sitting in its display case.

It is the heaviest mounted gem in the National Gem Collection,
and is framed in a brooch setting surrounded by twenty round brilliant-cut diamonds,
totaling 16 carats.

The piece was a gift to the Smithsonian Institute from Mrs. John A. Logan in 1960.


The Mackay Emerald Necklace


The stunning 167.97-carat Mackay Emerald was mined in Muzo, Columbia.

The largest cut emerald in the National Gem Collection,
it is set in an Art Deco diamond and platinum necklace designed by Cartier Inc.

In 1931, Clarence H. Mackay presented the necklace as a wedding gift to his wife, Anna Case,
a prima donna of the New York Metropolitan Opera from 1909 to 1920.

The piece was donated to the Smithsonian Institute by Mrs. Anna Case Mackay in 1984.


The Mackay Emerald Necklace makes an appearance at the 2001 Tucson
Gem & Mineral Show. It was displayed in its own dedicated case and
diligently guarded by its own dedicated Tucson police officer.

The Maria Alexandrovna Sapphire Brooch


In the Great London Exhibition of 1862,
a sapphire weighing 260.37 carats was purchased by Russian Emperor Alexander II
and presented to his wife Empress Maria Alexandrovna.

This rare treasure was described as
"unique ... for its combination of size, color, clarity and extraordinary cut."

Today, this magnificent piece of history is in the Russian Diamond Fund,
where it is proudly shown in Moscow, Russia.


In 1971 the USSR paid tribute to the brooch along with several other
pieces from the collection by featuring it on a postage stamp.
