How can it be recognized whether the gemstone has been filled? There are often small round bubbles in the filling, which is impossible in natural rubies. However, the bubbles are usually very small and can only be seen with the help of professional magnification tools such as gem microscopes. A more effective method of identification is to carefully observe the surface and various angles of the gemstone with a 10x magnifying glass.
The hardness of the high-refractive-index glass filled in the ruby cracks is very low, far less than the hardness of rubies. Therefore, after the same intensity of surface polishing, the surface of the glass with low hardness in the cracks will appear concave compared to the surface of the ruby with high hardness. Go down some.
In addition, although the refractive index of the glass filled with gems is high, it is still different from the refractive index of rubies, and the fillings will show a sparkle different from the body color of the gems. Rotate the gem to observe carefully, and you can see that there are some small flashes such as blue-violet, purple, and orange inside the gem. When there are a lot of fillings, some angles can even see the original red gems showing a large area of blue-violet.
Diffusion treatment is the most common treatment method for sapphire. Diffusion treatment can make blue sapphires that originally have no color, and can also make sapphires that have no starlight effect to produce starlight.
Diffusion treatment is different from dyeing in the usual sense. It does not use any dyes, but adds color-causing elements to the corundum for its color. Conventional methods can only make artificially added color elements penetrate into the surface of the gem. At this time, only a thin layer on the surface of the sapphire is blue, and the center is colorless. But it is impossible for us to distinguish the gemstone by cutting it from the center. So, how can we know whether the color of the gemstone is overall or just on the surface? Just take the following observation method, and you can see if there is any problem with the color of the gemstone.
To observe the gem from the bottom, add a layer of diffuser between the light source and the gem. Where can I find the diffuser? Don’t worry, the facial tissue used daily is an ideal diffuser.
Don’t underestimate this little facial tissue. It’s like looking at a magic mirror. The problematic sapphire is observed in this way after such a photo. If the sapphire is diffused, you will see the phenomenon in the picture. The color is concentrated to the gem. At the ridgeline of the stone, the color at the facet is lighter, and the whole gem has a spider web-like appearance; and if there are cracks, the color at the cracks will be very dark. And the sapphire that has no problem is not afraid of this magic mirror, no matter how you take it, the color will not show this phenomenon.
However, with the continuous improvement and improvement of diffusion technology, a new kind of sapphire that we call “body diffusion” has appeared on the market. The so-called “bulk diffusion” is to make the color-causing elements penetrate into the whole gemstone and not just limited to the shallow surface. However, with the current technology, the bulk diffusion method usually uses Be element to enter the entire sapphire, and Be will cause the sapphire to appear bright orange-red. So this new diffusion method is also called “Be diffusion”. When the “Be diffusion” sapphire is viewed with the observation method introduced above, the color will not show a “cobweb” like the traditional surface diffusion sapphire, but will be uniform.
