Gemstone Treatments:
-Treatments for gemstones-
Untreated:
This means there was no treatment what-so-ever of the gemstone. It is all 100% natural.
Heated:
Heat treatment is a normal/common treatment among some gemstones. This treatment is to lighten up a color sometimes improving the color under high temperatures. A very common treatment is very common among rubies, sapphires, tanzanites, and zircons.
Irradiated:
Irradiated treatments is something that will completely change a color of a gemstone with radiation.
Almost all blue topaz in the market today is actually the product of radiation. This treatment is the most expensive of all treatments because it involves in neutron exposure. "Swiss Blue" and "London Blue" topaz are prime examples of irradiated gemstones.
Fracture Filled:
Fracture filling is a common treatment in rubies, sapphires, peridot, emeralds, and aquamarines today.
It involves in filling a flawed gemstone with a lead-based glass to fill the "dead" spots of a gemstone. Also to help hide some internal fractures that may distract the eye from the stone's dispersion, or sometimes improve durability. Some people refer stones with this treatment as a "hybrid" gemstone.
Diffusion:
Simply put it as a lab created gemstone.
In lab environments, the crystals is grown under controlled conditions. It is simply a man-made gemstone.
For a collector of genuine gemstones, this treatment you should be cautious about.
Beryllium:
It is essentially a form of heat treatment for sapphires. Simply adding the element beryllium into a gemstone. This treatment will alter the blue tones to create a completely new coloration.
Doublet:
A doublet is simply a soft gem is capped with glass or colorless quartz to make it harder, and sometimes to improve a color. This treatment is well known for precious opal, it is capped with glass or colorless quartz by using a special gem cement then heated.
Triplet:
Triplets are just like doublets, but with four layers. This particular treatment is usually reserved for lesser grade opals to help improve their durability, color-play, and longevity. Both doublet and triplet treatments are sometimes referred to as "composite" treatment.
Oiled:
Oiled treatment is a common treatment among emeralds and rubies.
What this treatment does is hides flaws on the surface of a stone. It is common practice, but accepted as a treatment for collectors.
