Aquamarine refers to the beautiful azure blue to sea blue emerald variant, and it can also be called sky sapphire and water sapphire. The gem industry in my country also calls it “cristallo blu”. It is considered to symbolize “composite, brave”, “happy and longevity”, and is designated as the birthstone in March.
Because aquamarine has a hollow or liquid-filled slender tubular inclusion, when it is densely arranged, the cat-eye effect can be figured out. Not long ago, this rare aquamarine cat’s eye was discovered in the Altay region of Xinjiang, my country. This gem is not completely transparent, but it is conducive to the cat’s eye effect.
The quality requirements for aquamarine are clear and transparent. The color should be darker sea blue, and the crystal should be larger. It is best to cut out the ring surface above 10ct.
Aquamarine is a new species of emerald that has recently emerged. Although its value is far less precious than emeralds, it is widely used by people because of its beautiful and soft sky blue to sea blue and very transparent (except for those with cat-eye effect). Love, especially by European and American people.
Aquamarine is mainly produced in Brazil, Russia, Namibia, Madagascar, Mozambique and Zimbabwe, as well as India and Sri Lanka.
In the early 1990s, China found emerald mines of a certain scale and high economic value in Dayakou, southern Yunnan Province. There are no less than 6 ore bodies, 20-280m long, 20-120cm wide, and extended depth. Around 50m. The longest crystal is 20cm and the diameter is 2.2~2.5cm. It can be processed into plain surface (ie bare body) jewelry for sale; a few specimens can be used as ornamental stone treasures.
Inoltre, many aquamarine producing areas in Xinjiang, Inner Mongolia, Yunnan and Hubei were also found. Tra loro, the Altay area of Xinjiang has the most abundant production and good quality. Large crystals weighing 8.8kg were produced in 1986. The entire Altay mountainous area has “Cina “Aquamarine Treasure House”.
