Peridot is the birthday stone of August. Many friends know the olivine because they were born in August. The price of olivine in green gems is not very high, usually about 300-500 yuan per carat. Commercially available olivines generally do not exceed 10 carats. Most of them come from Myanmar or the mainland. Among the olivines I have seen, the color of olivine in Myanmar is slightly greenish and yellow, and there is no green produced by Makouping in Hebei, China. Because the price of olivine is not high, it is advisable to choose a large size in the purchase, and the color is better with emerald green. Olivine is often used to make brooch, ring and earrings. It should be worn regularly to avoid collision with other stones and cause damage.

Purchase to decide:
(1) The first choice for the purchase of peridot jewelry should be whether its green color is pure and deep, and the yellow-green color is too much to reduce its value.
(2) Note that the interior should be crack-free and flawless, and the olivine with a low value is low.
(3) It should be noted that the jewels in the jewelry have burrs. It is best to choose straight edges and perfect cut rules.
Precautions
Peridot inlaid jewelry, a lot of fake, please pay attention to distinguish! The material of the main stone olivine used in this kind of jewelry is very small, so it is unsightly to use the naked eye to find out the true and false. The best way is to ask for the regular gemstone identification!
Maintenance:
The stone nature of olivine is relatively brittle. If it is suddenly heated, it will break and the toughness will be poor. If the packaging is not good, the collision during transportation will be damaged. When processing jewellery, be careful not to work under the blowtorch. In addition, olivine is also afraid of acid corrosion. Be careful to operate gently when changing stones. An experienced worker, when processing peridot jewelry, carefully removed the stone from the tire and worked again. Olivine must not be placed in acid to clean. Some chemicals in the solution will damage its surface and then heat up, which will cause the entire stone to be destroyed. The best way to clean the olivine is to use a brush and gently scrub with soapy water in clean water. It is not a good idea to wash the olivine with steam. The olivine is not suitable for cleaning in an ultrasonic cleaner.
Olivine is mostly short columnar crystal, brittle, easy to break, transparent and glassy. Olivine is also known as the dusk emerald, which refers to the thick green olivine. In addition, there are yellow-green olivine, golden green olivine, rich yellow-green olivine, and gems. The jewel is an extremely rare species.
When the olivine is heated, it is easy to break. When transporting the olivine, if it is not properly packaged, it will be easily damaged due to bumps and collisions on the way. This is because the olivine has poor toughness and is very brittle. When processing the peridot jewelry, do not work under the torch, do not give it a sudden heating, the heating must be carried out slowly, in addition, carry the olivine lightly and gently to prevent damage due to collision.
In addition, acidic substances can easily corrode olivine, taking care not to put olivine jewelry and acidic substances together. It is even more difficult to clean the olivine with acid. Because the olivine is washed in the solution, some chemicals in the solution will damage the surface. If it is heated, the whole olivine will be destroyed. Therefore, it is best to clean the olivine with a brush, put the olivine in clean water, brush it gently with a brush dipped in soapy water, or wash the olivine with steam.
The olivine in bulk is best packaged in a single package. This is because the loose olivines are put together and collide with each other, which is prone to scratches. [3]
In addition, it is important to note that when using detergent, face washing or bathing, remember to remove the peridot jewelry to avoid being eroded or contaminated by moist moisture, because the gaps and dead ends of the jewelry are easily deposited. Especially the complicated workmanship.
