Beryllium in Blue Sapphires, Both Natural and Diffusion-Treated
This information should enable gemological laboratories to distinguish blue sapphires containing natural beryllium from beryllium-treated blue sapphires. The amount of each trace element associated with beryllium is a possible key to identifying the origin of blue sapphires with natural beryllium content.
Beryllium-Treated Blue Sapphire • Lattice Diffusion of Corundum
Mar 1, 2006 · Beryllium-Treated Blue Sapphire • Lattice Diffusion of Corundum. In November of 2005, Bangkok's GRS announced that they had detected significant amounts of beryllium (Be) in a number of blue sapphires (Peretti et. al., 2005).
What Should You Know Before Buying Beryllium Treated Sapphires?

The heat treatment of corundum involving lattice diffusion of beryllium (Be) at temperatures over 1800°C has become a major issue in the gem trade.
Beryllium Treatment for Gemstones 'Be Heated' - Gemstone ... - GemSelect
Beryllium treatment (Be heat) is a recent addition to techniques for treating gemstones. Beryllium treatment is a form of heat treatment, mainly for loose sapphire, that adds the element beryllium to the heating process.
Over the past two years, the heat treatment of corundum involving lattice diffusion of beryllium (Be) at temperatures over 1800°C has become a major issue in the gem trade.
How to Determine if a Sapphire is Treated or Untreated - GemSelect
Beryllium treatment is a specific type of diffusion treatment that utilizes beryllium to alter the color of sapphires. This process can produce vivid and striking colors, but it may also lead to inconsistencies in color distribution and gemstone durability.
The diffusion of beryllium into corundum cre-ates yellow, orange, or brown color components. The effectiveness of this process in turning pale-col-ored or nearly colorless corundum into vibrant yel-lows and oranges is dramatic. No less dramatic is the alteration of pink sapphire to a …
Beryllium-Diffused Blue Sapphire - Ganoksin
Gem dealers in Bangkok, Thailand, are reacting to concerns that beryllium diffusion is being used on blue sapphires. Beryllium diffusion typically brightens the color of ruby or sapphire, making a stone more yellow, orange, or red, depending on the original color.
Natural Diffusion Blue Sapphire, Beryllium treated blue sapphire, …
Beryllium is diffused in the sapphire to remove or lighten the blue color in overly dark sapphires. While initially doing the treatment there might be some traces of yellow color in the stone’s interior.
