It should be sapphire. Thai sapphire. Black blue, light gray blue. There is no silk -shaped bag in the crystal, but the fingerprint liquid wrap development. The most characteristic is the cracks of lotus leaf -shaped cloth around the black solid -state bag. Three groups of polyetry dual -crystal development, cracking along the dual -crystal surface.
The Chinese sapphire. In the 1980s, many sapphire mines were found in the basalt along the coast of the eastern part of China. Among them, Shandong (Changle) sapphire is the best quality. The crystal is six -square bucket, with a large particle size, generally above 1cm, and the maximum can get up to kucke. Due to the high iron content, sapphire is mostly nearly charcoal -black blue, blue, green and yellow. Mainly blue blue. There are very few wraps in gem -grade sapphires. In addition to the black solid buns, fingerprints are still visible. No silk -shaped golden stones and diffuse liquid bodies. The flat color band in the sapphire is obvious, and the twin crystals are not developed. The exterior edge of the large crystal can be seen in the growth line of parallel six -square column. Shandong sapphire is high in internal defects and is high -quality sapphire.
The Australian sapphire. Australia is a place of production of sapphire. But due to the high iron content, the color of the gem is dark. Most of the dark blue, yellow, green or brown with nearly charcoal black. Dust -containing bag. Its gem characteristics are the same as Thailand and China, and they need to be changed before they can be used
