American Museum of Natural History - Gems

The Kazanjian Red Diamond is an extraordinary 5.05-carat red gem on temporary display in the Museum's Morgan Memorial Hall of Gems. Red diamonds are the rarest among colored diamonds. Only three 5-carat red diamonds are known to exist: the Kazanjian Red diamond, the trilliant-cut 5.11-carat Moussaieff Red, and the 5.03-carat De Young Red.

The original 35-carat piece of rough was discovered in Lichtenburg, South Africa
At 563 carats, the Star of India is the world's largest gem-quality blue star sapphire. Rutile, a mineral in the Star of India, gives the gem its milky quality and star effect. Tiny fibers of rutile in a three-fold pattern reflect incoming light in the star pattern.

This effect is called asterism.
The Patricia Emerald is a large and superbly colored specimen. At 632 carats, the dihexagonal, or twelve-sided, crystal is considered one of the great emeralds in the world. Found in Colombia in 1920, it was named after the mine owner's daughter.

The flaws in this emerald are normal but compromise the hard gem's durability. This specimen is one of the very few large emeralds that have been preserved uncut.
The Kimberley Diamond was originally discovered as a 490 carat crystal. The Kimberley diamond was cut into a 70 carat gem in 1921.

According to the museum, the stone was given its present emerald cut in 1958 to improve its brilliancy.

Silver in ancient Egypt

Gold was considered to be the skin of the ancient Egyptian gods and their bones were thought to be made of silver.

At beginning of recorded history, silver may have been unknown to the ancient Egyptians. They could obtain gold and electrum, which was a natural alloy of silver and gold, from the mountains of the Eastern Desert and Nubia. Early Egyptian language lacks a word for silver. They described it only as the "white metal", and when they did run across it, they seem to have regarded it as a variety of gold.

When silver was introduced into Egypt, it probably was more valuable than gold. It was rare, and on lists of valuables, items of silver were listed above those of gold during the Old Kingdom.

Jewelry made of silver was almost always thinner than gold pieces, as indicated by the bracelets of the 4th Dynasty queen Hetephere I, in marked contrast to the extravagance of her gold jewelry.
A silver treasure found at the site of Tod comprised vessels probably made in Crete. The hoard dates to the reign of Amenemhat II who ruled during the 12th Dynasty. (1962 BC)
By the Middle Kingdom, silver was less valuable than gold. By this time a much better supply of the metal had developed. During the 12th Dynasty, silver had acquired a value approximately half that of gold. By the 18th dynasty silver and copper had been established as a means of exchange.

Copper was valued at about one-hundredth the value of silver.
The rulers of the 21st and 22nd Dynasty, who were buried at Tanis used silver in their burials. Sheshonq II had a solid silver coffin with gilded details in the form of the hawk-god, Sokar.

Trimel Pharmaceuticals Corporation (TSX: TRL) announced today that the United States Food and Drug Administration (FDA) has approved Natesto™ (testosterone), formerly CompleoTRT™, the first and only testosterone nasal gel for replacement therapy in adult males for conditions associated with a deficiency or absence of endogenous testosterone. Natesto™ is self-administered via a nasal applicator thereby minimizing the risk of secondary exposure to testosterone of women or children.

“In my practice I regularly encounter men demonstrating symptoms of hypogonadism and physicians will increasingly see this as the North American population ages,” said Dr. Jeffrey Rosen, the medical director and founder of Clinical Research of South Florida (CRSA). “For these patients seeking to restore their testosterone levels, Natesto™ will offer an alternative delivery system that is safer and more convenient than the other options currently available on the market.”
