Yellow Sapphire

Yellow sapphire is a popular substitute for a yellow diamond, and yellow has become the second most popular sapphire color (after blue). A yellow sapphire can also be found in larger sizes, and stones over 5 carats are not uncommon. The yellow sapphire is said to channel the cheeriness of a lovely summer day’s sunshine, and it makes people happy just to look at it. The yellow sapphire will light up the wearer, whether it is worn as a ring, a pair of earrings, or a part of a necklace or brooch. Have a look at our portfolio of fine yellow sapphire gemstones!

The best yellow stones are from Sri Lanka, and purchasing from Crescent Gems gives you the best value for your stones as they come directly from the source.

Techniques range from simply throwing gems into a fire to be cooked to employing sophisticated electric or gas furnaces at specific pressures and atmospheric conditions. The treatment is permanent and heated stones do not require any special care.
