1. Heating

• Heating is the most pervasive treatment of gemstones including coloring, lightening, darkening, brightening, prιcising and the entire clarity of the gem. In rare cases, Heating changes the color and its beauty.

• There are numerous kinds of heated-treated-gemstones including Sapphires, Citrine, Pink Topaz, Aquamarine, Tanzanite, Rubies, Blue and Colorless Zircon, Amethyst and Tourmaline minerals, etc.

• The treatment of gemstone heating is irretrievable with respect to certain conditions known Standard-Gemstone-Heating-Treatment.

• There is no price distinction between the heated gemstone and unheated gemstone as it is undetectable.

2. Oiling

• Oiling to "Emerald" is natural and universal, because emerald is treated by a barrel of oil right after its exploration from the mine. While cutting of emeralds, the oil is commonly used as a lubricant on the cutter's part. The colorless oil leaches into the cracks on the surface of the emeralds. When the rupture contains the oil they are become less eye perceptible. To complete this procedure oil is hassled into the fissures of the refined stone.

• Rarely, the gemstones are decorated along with oils and lubricants, but they are merely oiled while their decreasing quality.

3. Irradiation

• It is basically the bombardment of substance used by subatomic particle and radiations. More often than not, the irradiations are followed by heating energy in order to generate a better and newly oriented color for the gemstone.

• Blue Topaz is the most universal gemstone in its treatment and rarely pale.

• The irradiated gemstones are generally regulated in the U.S by the Nuclear Regulatory Agency to make sure there is no dangerous-residual-radiation.

• The irradiation of blue topaz these days mostly create the shades which are not observed in natural blue topaz.

• The prices of irradiated blue topaz are not too much expensive as there is an enormous competition in the wholesale market.

• It is said that expensive and luxurious blue topaz can merely be found rarely as they are full of irradiation quality and dazzling sparks.

• Tourmalines are irradiated in order to darken the pink gemstones in red stones and these are impossible to differentiate from natural red gems. In such sort of condition, the tourmalines will be sold at a reasonable price even if the colors are comparable.

• Off-Colored-Diamonds are irradiated and heated in such a manner that these diamonds are turned into powerful colors like green, yellow, blue and brown.

• The irradiated off color diamonds are much less expensive in their purchase as they have diversity like gorgeous color, fascinating shape, design, grade and size.

• Pearls are the most cultural gemstones which are usually irradiated in producing the gray and blue colors, but dyeing in these colors is very universal.

4. Dyeing

• Dyeing the gemstones is the most common use which shows pervasiveness, acceptability and prevalence.

• These colors don't come into existence in their natural context while no trickery is drawn in but dyeing of different minerals like jade, lapis lazuli, turquoise and coral might be less acceptable.

• Mostly, the dyeing of gemstones is done in order to camouflage their poor quality goods.

• Last but not the least is the cheapness of dyeing gemstone which is absolutely important and worthwhile.

5. Bleaching

• Bleaching is such a treatment designed for the organic gemstones including ivory, coral, pearls and cultured pearls. This process lightens the color and keeps the mineral fine, shine, pervasive and undetectable.

6. Coating

• Coating is such a gorgeous treatment of gemstone used in order to polish and finishing the gemstone so that appearance looks quite prominent and elegant. It is rarely used in diamonds to enhance the prominence of the gemstone and its color. As a result, the buyer will be forced spontaneously to purchase the gemstone.

7. Surface diffusion

• This is used in Sapphires. Chemicals are suffused into the exterior of gems at an extreme heat.

• Surface diffusion is used on sapphires. Chemicals are infused into the surface at high temperatures. It can get better the color or build asterism.

8. Filling

• Filling is processed into gemstones with exterior particles and hollow spaces. Glass, plastic and other materials are mostly used to block up holes. This is periodically treatment with rubies. By close examination with magnification you may spot differences in surface luster. This is not a suitable treatment as it is done to swindle the consumer.

9. Lasering

• Lasering is hardly ever used in diamonds as the treatment maneuvers towards microscopic fissures into a diamond to provide access to an insertion which detracts from the prettiness of the minerals. The enclosure can then be lightened to formulate it less observable if it is not burned out by the lasering. Under intensified laser, the fissures are easily discernible when seen at a 90 degree angle to the drill hole. A lasered diamond is classified in the somewhat imperfect type in spite of any perfection in visible lucidity and must be valued in view of that.

10. Infilling

• It is a process used for breaking hollow spaces in glass, plastic and opticon so the flexibility and precision of a gemstone is remained persistent. This treatment is commonly used in emeralds, rubellite and tourmalines.

Analytical approach

In short, we can say that gemstone treatments are highly qualified and well-designed existing into different forms including infilling, coating, filling, lasering, diffusion, bleaching, irradiation, dyeing, oiling and heating and these are all where the most unified, universal, cultural, historical, ythical and modern treatments of the gemstones.
