Aquamarine is a kind of silicate containing beryllium and aluminum. Together with emerald, Ulamnu and tourmaline, it is called colored gems.

Aquamarine is mainly produced in sugar albite pegmatite in pegmatite deposits. The common crystal morphology is hexagonal columnar, and the aggregates are mostly columnar. Aquamarine belongs to silicate crystals in mineralogy, which can show different colors, mainly depending on the genesis and formation conditions of the ore.

Gems are beautiful and valuable stones among rocks. They are bright in color, crystal in texture, brilliant in luster, hard and durable, and rare. They are natural mineral crystals and can be used to make jewelry, such as diamonds, crystals, emeralds, rubies, sapphires and emeralds. There are also a few natural single mineral aggregates.

Extended data

Legend has it that aquamarine is produced at the bottom of the sea and is the essence of seawater. Therefore, navigators used it to pray for Poseidon's navigation safety and called it "the stone of luck". It is also considered as "the birthstone of March", symbolizing "calmness and courage" and "happiness and longevity".

The quality evaluation of aquamarine is evaluated from the aspects of color, clarity, cutting and weight. Pure color, no gray, no dichroism, strong and bright color has the highest value. Some aquamarine with directional inclusions can be processed into cat's eye effect or starlight effect, and aquamarine with special optical effect is more expensive. Aquamarine with the same color, clarity and cut, the greater the carat weight, the higher the value.

At the same time, the crystal mentioned in the question is a rare mineral, and the crystal itself is a kind of gem. The timely crystal belongs to the timely family in mineralogy.
