FUNDS FOR ASSETS

A more extensive procedure is the "diffusion treatment." Here, the gemstones are actually colored with coloring substances, with the penetration depth being only 0.01

to 0.5 mm. Therefore, the gemstones are only colored at the edges. Due to the high temperatures used in this method, the gemstones must be polished again, which
removes any material that has been colored. Therefore, these gemstones can be identified by their varying color intensities. The stone is immersed in a slurry of

titanium, beryllium, or chromium oxides at temperatures of 1,600–1,900 degrees Celsius.

Compared to a RUBY, burning or heating an EMERALD is of no use. Emeralds do not react to temperature and may even be destroyed by it. Emeralds are generally brittle

and exhibit natural cracks. It has therefore been recognized that these cracks can be made almost invisible to the naked eye by using colorless oils. Cedarwood oil,
which is often used for this purpose, has a light refraction very similar to that of emerald, thus making the cracks "disappear" to the human eye. Today, soft resins or

mostly synthetic resins are used instead of cedarwood oil, as these produce a more lasting result than natural oil and also have an even more suitable light refraction

than oil. These fillings are often hardened with a hardening agent or ultraviolet radiation.

In general, the following treatments exist for SMARAGD: Our group of companies has the gemstone experts who, according to the
methods described above and other processing principles, develop our RUBY
 those that enhance color (green-colored oils or resins for pale emeralds)
& EMERALD into high-quality and at the same time exclusive gemstones,
 those that enhance clarity (oils and resins)
whose value is achieved many times over through their further processing.
 those that enhance stability (especially resins for brittle gemstones)

All of the above methods can be detected in a laboratory under a microscope.
