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.

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.

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 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.
