Yellow Sapphires are bright gemstones that range in color from a "Light Buttery Yellow" (light fancy yellow), a "Medium Buttery Yellow" or "Light Canary Yellow" (fancy yellow), a "Rich Buttery Yellow" or "Canary Yellow" (fancy intense yellow), to a "Rich Canary Yellow" (vivid yellow). The 3 photos above reflect the variance in color, from Light Yellow similar to the Fancy Yellow Diamond color, to very Rich Canary Yellow similar to the Fancy Vivid Yellow Diamond color. Yellow Sapphire has become extremely popular, since they so closely resemble the color of a Yellow Diamond.
These faceted Gems are exceptional in jewelry, since their hardness is second only to Diamond. We carry only Top Gem quality Natural Yellow Sapphires, many of which are not treated. In recent years all Gem Quality Yellow Sapphire has become more and more of a very rare commodity, doubling in value in the past five years. These Top Gem Quality Yellow Sapphires are gaining great popularity as a highly valued Collectors Gemstone.
TREATMENTS - Almost all (99%) Sapphire on the market is routinely treated with 'heat' to enhance and stabilize the color. The typical heat treatment process is a permanent process and it does not normally adversely affect the performance, and durability of the gem, but in recent years demand for natural non-heated non-treated top quality Sapphire has caused these gems to command a somewhat higher premium, depending on the gem. When we disclose a gem as enhanced with 'heat', we are typically referring to the heat enhancement procedure performed in Sri Lanka right near the mines, using the lower temperature wood heat method. This 'blow' heat method typically is used on very very good quality Ceylon gems, only to slightly enhance the color and/or to stabilize the color from fading in sunlight. There's no need to worry when you see this enhancement disclosed. Almost all Ceylon Pink, Padparadscha, Golden, and Orange Sapphire on the market was subjected to 'blow' heat. This 'blow' heating method has been an accepted trade practice for many many generations. There are other types of heat enhancement procedures, however, one of which is a high temperature furnace fired method. This 'furnace' process is typically performed on Sapphire of a much lesser quality. The goal is to seriously enhance or alter the color and/or clarity of the stone. Most of these gemstones are highly heated, almost to the melting point of the gem, so it is 'cooked' over and over until the gem dealers feel it is a more desirable color and will fetch a better price in the market. We normally do not offer gemstones that have been highly heated.
CARE - It is usually safe to clean Sapphire in an UltraSonic Cleaner, and generally safe to use a steamer. The best practice is to use an Ionic Cleaner and/or warm soapy water and a soft brush as the best way to clean your Sapphire Jewelry.
