How jasper stone is formed
Diagnosing Jasper
Jasper stone (a type of jade) is one of the types of quartz stone that has chemical compounds based on silicon dioxide
More than 20% of high-quality dense jasper stones may be composed of various materials such as hematite, pyrolusite, clay or calcite
This stone has such a pebble structure and different types of jade that some scientists have even placed it in a separate category in the quartz group
These trihedral crystals of this stone with a microcrystalline structure can only be seen under very strong microscopes
This stone can be easily distinguished from other similar materials due to its high hardness and lack of cleavage (tendency to split and break in a certain direction)
:Jasper color
Jasper stone is colored and appears streaked and spotted
Various commercial names of this stone have been created based on the color, appearance and composition of this stone
There is no special advice or warning about the color of this stone, because its red color (the most common type of this stone) is due to the iron oxide in it
Also, its brown and yellow colors are equally common
Monochromatic types of this stone are very rare
In general, the main value of this stone is determined based on the color saturation of this stone
:The clarity and brilliance of jasper
Even in small pieces, jasper stone is non-glossy and matte, and it is better to always polish it to have a glassy and high-quality surface
Jasper cut and shape
This stone is cut in small pieces as a decoration and in the shape of a short hemisphere, and in larger sizes it is cut into various shapes such as round, oval, heart and tears
In addition, it is also used in stone mosaic works
Due to the layered nature of this stone, you must be very careful during cutting so that it does not crack
:Jasper stone processing
This stone is not usually processed, but some of its types are colored to resemble other types of jasper

Jasper’s origin and resources
This stone is found in many places in the world such as Canada, Brazil, Egypt, Australia, India, Indonesia, Kazakhstan, Madagascar, Mexico, Russia, Uruguay, Venezuela, and in the American continent in Arizona, Arkansas, California, Texas, Oregon, Washington
Ideas for jewelry design with jasper
As we said, jasper is from the family of quartz stones – one of the most important groups of jewelry stones of all time
Unlike other colored stones, this stone is available in local jewelry stores
Due to its shape, motifs, color, abundance and affordable price, this stone is very popular among professional designers and designers who work in this profession
Quartz-jasper stone is considered a suitable stone for any type of jewelry design (necklace, necklace pendant and ring)
It has the durability and hardness necessary to make jewelry and use it in everyday jewelry without breaking or scratching
Depending on its use, this stone can have a modern, traditional, tribal and ancient design and generally does not require special maintenance
Like some stones, jasper is a favorite stone of men and women due to its variety and availability as well as its special and unusual shape
Tip: When buying precious stones, pay more attention to their size than their carat weight
The ratio of size to weight of colored stones is different
In weight comparison, some of them are bigger and some are smaller than diamonds
:Maintenance and cleaning of jasper stone
Since quartz stone belongs to the quartz family, it is very durable compared to most other stones
This stone is easily cleaned with warm water and a little soap and a brush or soft cloth
Be careful to rinse the stone completely before drying
Although this stone is very durable, there are some materials that can scratch it, such as diamond, topaz, ruby and sapphire
Avoid using and storing stones next to each other to avoid scratching or breaking the stones
Like the rest of the stones, avoid strong chemicals such as sulfuric acid, bleaches, etc. to wash and care for them separately
Jasper is a very porous stone, which makes it easy to stain or absorb dyes and chemicals
Avoid exposing it to heat for a long time because heat causes the stone to change color
Remove all jewelry before engaging in strenuous activities, exercising, or bathing
The best way to store it is in a soft cloth or in a gold and jewelry box covered with cloth
