Golden Yellow Sapphire Information

Specific Gravity :4.00 (+.10,-.05)

    Yellow Sapphires are bright gemstones that range in color from a Light Buttery Yellow to very Rich Golden Yellow. Golden Yellow, also known as Sunshine Yellow Sapphire, has become extremely popular.
    These faceted Gems are exceptional in jewelry, since their hardness is second only to Diamond.  We carry only Top Gem quality Natural Golden Sapphires. In recent years all Gem Quality Golden Yellow Sapphire has become more and more of a very rare commodity, doubling in value in the past five years.  These Top Gem Quality Sunshine Yellow Sapphires are gaining great popularity as a highly valued Collectors Gemstone.

TREATMENTS - Allmost all Ceylon Golden Yellow on the market is 'heat' enhanced. There are 2 common heating methods. One is the 'blow' heating method, which is low temperature (1300^oF) heat using wood or coal and a coconut shell blow pipe. This 'blow' heating method has been an accepted trade practice for many many generations. The other heat enhancement procedure is a high temperature furnace fired method. The 'furnace' process is typically performed on Sapphire of a much lesser quality to seriously enhance or alter the color and/or clarity of the stone. Furnace heated gemstones are heated to the point of almost melting the gem (3635^oF), and the crystal is 'cooked' over and over until the gem dealer feels it is a more desirable color and will fetch a better price in the market. We do not offer gemstones that have been subjected to that high temperature furnace fired method.
CARE - It is usually safe to clean Sapphire in an UltraSonic Cleaner, and generally safe to use a steamer, but we strongly recommend Ionic Cleaners and/or warm, soapy water and a soft brush as the most trustworthy way to clean Sapphire jewelry.
