Crystal is a beautiful and mysterious mineral that is adored by many people in daily life. It has various classifications, and different types of crystals are believed to possess different effects.
1. Classification of crystals
1. Sort by color
Colorless crystal
Colorless crystal is the most common type within the crystal family. It is pure and transparent, resembling clear ice. This crystal has a relatively simple internal structure with fewer impurities. In nature, colorless crystals often occur in the form of crystal clusters, with the crystal shape mostly being hexagonal prismatic, topped with a hexagonal pyramid. It is an important material for making optical instruments due to its high transparency and stable refractive index.
Purple crystal (amethyst)
Amethyst is renowned for its elegant purple hue. The color of amethyst varies from light lilac to deep grape purple. Its color is primarily attributed to the presence of trace amounts of iron in the crystal. Amethyst typically forms within cavities of volcanic rocks, and its crystal morphology resembles that of colorless quartz, also exhibiting a hexagonal prism shape. High-quality amethyst crystals are complete, with uniform and rich colors, and contain few visible impurities.
Yellow crystal (topaz)
Citrine exhibits a warm yellow hue. Its color is attributed to iron ions, and some citrines may have transformed from amethysts through natural geological processes such as heating. Citrine is highly sought after in the market due to its bright and cheerful colors, ranging from light yellow to orange-yellow. Its crystal shape resembles other crystals, but sometimes unique textures can be found within some citrine crystals.
Pink crystal (Pink Quartz)
Pink crystal, also known as hibiscus stone, boasts a gentle pink hue. The color of this crystal is primarily attributed to the trace amount of titanium it contains. Typically, pink crystal has a milder texture, and its transparency may be slightly lower compared to other crystals. It is frequently crafted into various jewelry, particularly bracelets and necklaces, and is highly favored by women. The crystals of pink crystal often take the form of blocks or columns, and larger raw stones of pink crystal can be found in some mineral veins.
Black crystal (such as tea crystal, ink crystal, etc.)
Black crystals include varieties such as tea crystals and ink crystals. Tea crystals have a lighter color, appearing dark brown or dark yellow, somewhat resembling the color of strong tea. Ink crystals, on the other hand, have a deeper color, almost black. Their colors are related to impurities and trace elements inside the crystal. These black crystals have a tight crystal structure and high hardness, and are often used to make crafts or decorations.
2. Classification based on the internal structure and morphology of crystals
Rutilated Quartz
Hair crystal is a type of crystal with needle-like or filamentous mineral inclusions inside. These inclusions grow inside the crystal like hair strands, hence the name. The types of inclusion minerals in hair crystals are diverse, with rutile, tourmaline, actinolite, etc. being common. If the inclusion is rutile, golden hair-like objects can be seen under light, and this type of hair crystal is called titanium crystal, which is a fine quality among hair crystals. The crystal shape of hair crystal is similar to ordinary crystal, but its unique internal structure makes it have special ornamental and collectible value.
Ghost Crystal
The interior of the ghost crystal contains inclusions in various shapes such as cloud-like and pyramid-like, in different colors like green or white. The green inclusions inside the green ghost crystal resemble a jungle or aquatic plants, which is very peculiar. The formation of ghost crystals is related to the changes in the geological environment during the crystal growth process. The different shapes and colors of inclusions endow ghost crystals with unique charm. It is also one of the varieties that crystal enthusiasts like to collect.
druse
A crystal cluster is an aggregate formed by the growth of many crystals gathered together. These crystals usually share a common growth substrate, and the top of the crystals grow in the same direction. Crystal clusters come in various shapes, such as fan-shaped and spherical. The crystals in the cluster are interconnected, forming a unique aesthetic. In mineralogy, crystal clusters are important specimens for studying the growth patterns of crystals, and they are also a very popular ornamental stone.
3. Classification by crystal origin
Brazilian crystal
Brazil is a renowned crystal production hub in the world. Brazilian crystals are abundant and of high quality. The amethysts produced in Brazil are rich and vibrant in color, with large and intact crystals. Brazilian topaz is also famous for its bright color and pure texture. Furthermore, Brazil produces a wide variety of crystals, including a large quantity of rock crystals and hair crystals. Brazilian crystal deposits are widely distributed, and the mining history is long. Many world-renowned crystal specimens originate from Brazil.
Chinese crystal
China boasts a wide distribution of crystal production areas.

Donghai offers a diverse range of crystal varieties, including colorless crystal and pink crystal. Hainan in China also produces crystals, which are characterized by high transparency and some crystals containing unique marine element inclusions. Furthermore, crystal deposits can be found in places like Yunnan, where the produced crystals exhibit local characteristics in terms of color and crystal morphology.
