Red

None of our rubies or sapphires have been diffusion or Beryllium treated, we don’t consider the practice an acceptable form of treatment since little is known about long term effects/durability.The finest rubies look like someone painted a swatch of fluorescent red directly across them. It is an almost glowing red, diffused well through the stone, and is rooted from the unique property of fine Rubies, a rich red fluorescence. While Burma (or sometimes called the Mogok Ruby) is the traditional source for the finest rubies, good stones are a rare find anywhere, the best stones contain tiny amounts of rutile silk which give these rubies their awesome crimson glow. Some neat facts and lore concerning rubies:

At Sotheby’s New York’s October 18, 1988 sale, Alan Caplan’s 15.97 ct Burmese ruby sold for $3,630,000, or a startling $227,301/ct (most of ours are less!)
Few named rubies:
167 carat Edwardes ruby (British Museum)
100 carat DeLong star ruby (Am Mus Nat Hist)
138.7 ct Rosser-Reeves star ruby
Many believed that rubies possessed an inner flame which burned eternally.
The Burmese believed rubies ripened like fruit, and that the redder a ruby, the more ripened it was. If a ruby was flawed, it was considered over-ripe.
Although The Black Prince Ruby sits in the Imperial State Crown in London, it is actually a 170 carat spinel
