Gemstone Treatment |
|
|
The process of enhancing the quality of gemstone in some extent by some procedures
is called Gemstone Treatment. Many natural gemstones found today are treated to
improve their appearance and quality. Some different types of treatments are:
1. Cavity Filling
2. Fracture Filling
3. Coating
4. Luster Enhancement
5. Impregnation
6. Diffusion Treatment
7. Dyeing
8. Heat Treatment
9. Irradiation
10. Reconstruction
Some of these treatments are permanent and some are not and some are meant to make
a less desirable stone more valuable. While some of these treatments are also common
to the industry, it is important that the consumer be told at the time of the sale
that the stone has been "enhanced" to look better. Heating of gemstone is considered
as the most common and old practice in gemstone treatment. There are certain new
practices that are more controversial and are not always welcomed by the gem society.
Some treated gemstones need extra care while cleaning and wearing.
At Ninci.com, we carry a large range of gemstone jewelry and only few of them have

are globally accepted by all the gemological society and considered as a regular
phenomena. Here below is a list of the gemstones that are being treated with the
