Crystal ornamental stone is the most representative work of natural crystal, and it has ornamental properties that other gemstones do not have. Whether it is jade or jadeite, it must be carved to reflect its value, and the crystal ornamental stone only needs to polish the surface, that is, to show the substance wrapped in the crystal, and directly appreciate the original crystal stone.
Naturalness
Naturalness is the basic property of crystal ornamental stones. Usually, the overall shape of crystal minerals has a high ornamental value without ornamentation, but the inclusions of crystal ornamental stones often need to be properly polished, so that it is more convenient to view the inclusions inside the crystal.
Singularity
Crystal ornamental stones are often very strange in terms of shape, texture, internal characteristics, etc. Nature has infinite scenery, which can be found in the inclusion crystal species.
Rarity
Natural crystal is a non-renewable resource, with the deepening of development, the stock of natural crystal has become less and less, for sustainable development, the Donghai County Government has long formulated a policy to protect local resources and encourage the development of overseas crystal resources, however, overseas resources are also becoming less and less, many countries have raised the threshold for mining and exporting natural crystal, and the price of foreign crystal entering the East China Sea market has skyrocketed year after year, among which the price of ornamental crystal is faster than that of ordinary crystal.
durability
The chemical composition of crystal is mainly silica, and the chemical stability of crystal is quite good; Crystal has a great hardness, with a Mohs (Moss) hardness of 7. These determine that the crystal will not rot and deteriorate, is durable, easy to preserve, and is very suitable for collection.
Inclusions
There are a variety of mineral inclusions inside the crystal, and the various landscapes formed can be observed with the naked eye, and such crystals are inclusions crystal ornamental stones. Because the crystal itself is a gemstone, people call the inclusion crystal “gem-quality ornamental stone”. The inclusions crystal ornamental stones are unique and have extremely high appreciation and collection value.
The crystal ornamental stone of inclusions can be divided into the following three types according to the order of the formation of its inclusions:
The first is the “whole inclusion”, which wraps these substances in the crystal when it crystallizes, and most of the various scenes formed by such inclusions maintain the original state of the crystal crystallization, that is to say, it is preserved in its original state for hundreds of millions of years, and is rarely affected by the natural environment.
The second is the “semi-inclusion”, after the crystal crystallization, due to the influence of the earth’s gravity and the cracks, some substances outside the crystal penetrate into the crystal through the cracks of the crystal, part of the crystal is wrapped in the crystal, and the other part is exposed outside the crystal. We can see the cracks that seep into the crystal, often referred to as “channels”, and the inclusions formed by this kind of inclusions are relatively more affected by the natural environment and time, and the corresponding value is relatively low.
The third is the “leather scene”, because some other minerals and crystals coexist, or due to the erosion of other substances and adhere to the crystal surface, or the crystal is affected by the natural environment, the crystal appears on the crystal surface, forming some scenes or patterns, this landscape exists on the crystal surface.
Crystal inclusions can be contained in a wide variety of inclusions, from gases and liquids to minerals and even gemstones. According to the content of the inclusions, the inclusions are often divided into the following eight categories:
Crystal cat’s eye, common titanium crystal cat’s eye, copper shun hair cat’s eye, quartz cat’s eye, green hair crystal cat’s eye.
Starlight crystal, visible starlight titanium crystal, starlight pink crystal, star quartz.
Titanium crystal flowers, which are composed of three groups of titanium crystals arranged in a plane, are extremely beautiful and rare.
Water urchin crystals, including gaseous, liquid, solid, sometimes can coexist at the same time polymorphism, colorless, in some cases can be seen red, green, yellow, blue, black, etc.
Hair crystals, including titanium crystals, copper hair crystals, green hair crystals, black hair crystals, silver hair crystals, variegated hair crystals, among which titanium crystals are the most precious, and a few titanium crystals are comparable in value to diamonds, rubies and sapphires, as well as emeralds.
Rabbit hair crystal, with red, yellow, white and other colors, is mainly composed of fine hair-like structures.
Ghost crystal, divided into green ghost, red ghost, white ghost, etc., is mainly composed of chlorite, of which green ghost belongs to the precious variety.
Landscape crystal is the crystal composed of various special shapes of the inclusion, some like landscapes, some like people, some like words, some like animals, plants, utensils and so on.
Rough stones
Crystal rough ornamental stone, from the literal sense: the original appearance of the ornamental crystal stone, that is, the inclusion crystal and the primary color crystal after polishing and peeling, do not need to be carved and do not seek the pictogram has a very high ornamental value and collection value. This kind of crystal ornamental stone has very high requirements for texture, crystal crystal is transparent and clean, the color is gorgeous, the artistic conception is bright and profound, and its value characteristics are just like diamonds, and the value of the stone itself is real.
The crystal rough ornamental stone fully embodies the essence of natural crystal, and the polished crystal rough ornamental stone is exquisitely clear, crystal bright, and the unique design shows the charm of the crystal just right. If you want to simply appreciate the crystal, the crystal rough ornamental stone is your best choice, giving people a feeling of returning to the basics.
Crystal clusters
This type of crystal ornamental stone is specifically referred to as a crystal cluster, which is a combination of many crystals that grow together in a single crystal. The crystal cluster is famous in the crystal appreciation world for its crystal clarity and unique shape.
The appreciation and evaluation of this kind of crystal crystal cluster ornamental stone mainly emphasizes the integrity of the crystal, the variety of precious (such as amethyst, smoky quartz, hair crystal, etc.), the peculiar shape, and the presence of precious crystals (such as cinnabar, stibnite, etc.). Crystal clusters are produced in the geode of ore deposits, and it is rare to have perfect appearance, and it is difficult to collect them intact and undamaged, so the cost of collecting them is relatively large, and the value of high-quality crystal clusters is also expensive.
Characteristics of several common varieties of crystal cluster ornamental stones
| Smoky quartz | Colorless spar |
|---|---|
| Colorless crystal | Colorless spar |
| No cracks or other defects. | |
| Smoky Quartz | This spar is produced under pure conditions and is completely colorless and transparent. |
| Smoky quartz transitions from light yellowish brown to brown and then deepens to an almost black color | |
| citrine | The color of amethyst is grape purple, light purple, and also dark red. |
| Black Crystal | Citrine is a type of smoky quartz that comes in different shades of brown color. |
| amethyst | The colors of amethyst include grape purple, light purple, and deep red. |
| The color of amethyst is grape purple, light purple, and also dark red. | |
| citrines | Natural citrine is very small in number and its price is expensive. |
| There are very few natural citrines and they are expensive. | |
| It can be found in all kinds of colored crystals. Among the various colored crystals, there are needle-like, hair-like or fibrous crystals, | |
| Hair crystal, bristle crystal | Some are water-striated, swirling, fan-like bristle needle-shaped, bidirectional cross or multi-directional cross, |
| Such spars are commonly known as hair crystals and bristle crystals. | |
| Hair crystals, bristle crystals |
Geodes
Crystal caves include amethyst geodes and cornucopias, which generally contain quartz crystals.
Geologists do not have a widely agreed theory of geode formation, but it is believed that geodes can form in any buried cavity. These cavities can be bubbles in igneous rock, cavities under tree roots, or even burrows dug by animals. After a long period of time, the outer wall of the cavity hardens and dissolved silicate or calcite is deposited onto the inner wall. Over a long period of time, the slowly infiltrating mineral causes the crystals to crystallize inside the cavity.
monocrystalline quartz
| White Quartz | Amethyst |
| Citrine | Smoky Quartz |
| Rose Quartz | Milky Quartz |
| Rutilated Quartz | Cats Eyes |
| Red Quartz | Chorite-Crystals |
Cryptocrystalline quartz
The crystals are so fine that they need to be seen clearly with a microscope, and they appear smooth and lumpy in appearance. The most common is all kinds of agate
| Stripped Agate | Moss Agate |
| Blue Lace Agate | Agate with Water |
| Carnelian |
