1, see how many cracks there are.
Observe the cracks and impurities on the original stone with naked eyes or a magnifying glass. The fewer cracks, the better, so that the polished product is more complete. But friends should not pursue perfection too much. Cracks are very common, just a matter of how much and how deep.
Step 2 look at the original stone skin
In the process of amber formation, a rough layer will be formed on the surface, which is mineral skin. The floating skin of the sea is thin and the skin is thick. The thinner the skin, the better. First of all, it is easy to observe the inside of amber. Secondly, it shows that the higher the content of valuable amber, the less waste is treated and the loss is reduced. The thicker the skin, the higher the waste. Comparatively speaking, the material with thin skin is light in color, while the material with thick skin is heavy in color, that is, there are more beeswax.
Step 3 look at the weight
Amber is priced by weight. The heavier and rarer amber raw materials of the same variety and quality are, the higher the price is, and the more valuable it is to collect.
Step 4 look at the shape
If you are ready to play with it after polishing, you can choose amber rough stone with full skin and weathered lines, and it will be better to rub it in your hand. If it is for wearing, you can choose a flat and regular shape, which is more beautiful to wear; If it is used for carving, you can choose a piece with full shape and no obvious grooves and holes on the surface, so that you can better design the original stone and carve fine products more easily.
5. See if the texture is transparent.
Hit the original stone with a strong flashlight and observe its light transmittance by backlighting. The stronger the light transmission, the more transparent amber is, the less cracks there are, and the higher the quality is naturally. If it is completely transparent, it is amber; If it is slightly translucent, it is white beeswax; If it is moderately transparent, it is yellow beeswax; If it is partially completely transparent and partially moderately transparent, it is half honey and half pearl, which is golden honey.
6. Look at this color
Mineral skins are different in depth, and the color of mineral skins can tell what beeswax is inside. For example, gray mineral skin, the interior is generally white beeswax; Black mineral skin, the interior is generally Jin Po; Red mineral skin, with honey-colored beeswax inside. If the original stone has a window, it is best to observe the internal situation carefully through the light to determine the color of amber. The more popular the color, the rarer it is, the more expensive it is, and the higher the collection value.
Of course, to be exact, there is no standard for the selection of amber rough stone, which mainly depends on your own needs and preferences. And playing with the original stone is risky, mainly for fun. Friends who haven't tried can try. Try to choose the original stone with windows. If the meat is exposed, it will be clear and the risk of buying will be much smaller. Choosing amber rough stone is fun, with both surprises and risks.
