Are Semi-Precious Natural Stones Laboratory Tested?

Yes, laboratory testing can and should be performed on semi-precious natural stones . While not as common as precious stones, these stones are heavily imitated in the market and are classified according to quality. Authenticity and quality cannot be determined solely by appearance; only expert laboratory analysis can confirm this.

1. What Does Semi-Precious Stone Mean?

Semi-precious stones are naturally occurring stones that have high aesthetic value but are not classified as "precious" like diamond, ruby, or sapphire. Many stones, such as amethyst, agate, labradorite, tourmaline, aventurine, malachite, citrine, and fluorite, are included in this group.

These stones are frequently chosen for jewelry, decorative objects, and collections due to their elegance and naturalness. However, originality and quality cannot be determined solely by color or luster.

2. Why is Laboratory Testing Necessary?

Painted stones, glass-mixed replicas, and synthetic counterparts abound on the market. Cheap imitations of some stones, in particular, can mislead consumers. Therefore, the stone:

• Whether it is real or not ,

• Whether it is natural or heat treated ,

• Whether it contains synthetic additives or not ,

• Origin ,

• Mineral structure and chemical composition

Details such as these can only be revealed through professional laboratory analysis .

3. What Tests Are Used?

Semi-precious stones, just like precious stones, can be tested using the following scientific methods:

• Spectroscopic Analysis (UV/Vis, FTIR): Determines the optical and chemical properties of the stone.

• Density Measurement: Real stones have a characteristic density.

• Refractive Index Measurement: The type of stone can be identified based on the behavior of light passing through it.

• Microscopic Examination: The internal structure of natural stones and synthetics can be distinguished under a microscope.

• X-Ray or Raman Spectroscopy: Scientifically reveals the mineralogy structure of the stone.

4. International Documents Like IGSL Certificate

At Safnaturel, we work with reputable institutions like IGSL (International Gemological Scientific Laboratory) to have our stones analyzed and issue a certificate specific to each product. These certificates are issued not only for precious stones but also for semi-precious stones .

Thanks to these certificates, our customers can be sure that the product they have has been described with scientific accuracy after purchasing the stone.

5. Security for Investment and Collectors

Laboratory testing is crucial not only for aesthetic purposes but also for stones purchased for collections, gifts, and investments . These tests provide documented assurance that the stone will retain its value if resold or resold in the future.

Conclusion: Looks Can Be Deceiving, Science Can't

Semi-precious stones, contrary to their name, are extremely valuable. The only way to prove this value is through expert laboratory testing .

At Safnaturel, we verify the authenticity of each stone not just by word of mouth, but with scientific documentation. This way, we offer our customers transparency, honesty, and lasting trust.
