If you want to find the best quality gemstone, firstly you should know the gemstone treatments. Jewelry dealers may treat gemstones in hopes of getting a higher price, today let us learn these gemstone treatments in detail.
Dye: This is the most common treatment used. On clear gemstones, dye may be visible in cracks that are darker than the rest of the stone. Sometimes dye appears as a residue that rubs off or white patches. Lapis lazuli beads and rose quartz beads are commonly dyed. Amethyst and Citrine are often dyed. Black Onyx is permanently dyed in normal processing.
Heat Treatment: Amethyst, Aquamarine, Ruby, Tanzanite and Topaz are often heated at high temperatures to enhance color.
Irradiation: It is common to irradiate Aquamarine, London Blue Topaz, Emerald, and Diamond as well as other gem stones. This treatment brings out color and removes imperfections. Many dealers know if the gemstones beads they are selling have been irradiated. Honest ones will tell you if they are aware of the treatment.
Coatings: Jasper beads are often dipped in petroleum products to bring out color and to seal it. Emerald is oiled; turquoise beads are waxed.
Gemstone Swap: When a deal seems too good to be true, the dealer may be substitution one gemstone for another. For example, dyed howlite beads are often substituted for Lavendar Jade.
Fake Gem Stones: Some dealers will try passing off fake gems instead of natural ones. There are fake stones for most gemstones on the market. Always ask what gemstone something is if you are not certain. Honest wholesale beads dealers will tell you. If a gemstone looks too perfect it may be fake, irradiated or dyed. I avoid laboratory made products also known as synthetics (unless getting a really good discount).
