How to learn jewelry identification and where to learn better

Suggestion: If possible, you can go to gem manufacturers to do a short -term training, and then go to the inspection to test for 1 year. It is the best path.
The tool for identification of jewelry:
: A magnifying glass
is very similar to diamonds and is the best substitute for diamonds. The appraisal method is that because the vermiculite has polarization and a large double refractive index, when the vermiculite edge after 10 times the large mirror is used to observe the processing of the processing, it can be seen from its top surface. Shadow, and diamonds have no phenomenon.
amplified mirror identification jewelry
: Portable microscope
ININTENTENING Portable scanner to identify jewelery. Now with the advancement of technology, glass products are the largest. It is also difficult to distinguish, and it is easy to distinguish glass products with portable microscope (such as Eniti, Di Guang, etc.). Because glass products are produced
Iney to show that the microscope watching jewelry chart
has a bubbles during the process, watching glass products with a portable microscope, enlarged to 200 times, and you can clearly see the bubbles mixed in the glass. This can be distinguished whether it is glass products.
three: spectrometer
The spectrometer used for jewelry appraisal is currently many. The Opal3000 Pro Jewelry Appraiser spectrometer of Fuxiang Technology has improved the sample test method of the original jewelry appraisal equipment. It is more convenient and faster to measure various jewelry samples, which is very suitable for laboratory use.
four: pen -style conservation flashlight:
It is used to observe the transparency of thick gems. The electric beads of the concentration should be reached on the pen, and the pen should not be protruded, otherwise it is not convenient to observe.
The crystal identification as an example:
The natural crystal is clear and transparent, often contains cloud -like, star dot or flocculable gas bodies, and often has a slight crack. In addition, natural crystals are polarized. It can be seen that the phenomenon of dual crystal, such as crystal sphere, from top to bottom, meet with dual phenomena. Artificial synthetic crystal or glass products are pure in the body without cracks, and there are often small bubbles inside. The sphere looks from top to bottom, and the double shadow of the line below cannot be seen. With your hands, you can feel that the proportion of the synthetic crystal is greater than the natural crystal; the natural crystal has a cold feeling, and the glass has a temperature.
The different identification methods made of fake crystals made of different materials
When the crystal jewelry is popular, many imitation products appear on the market, which not only causes consumers to trouble Professional and foggy.
If counterfeit products such as:
1. Pressure, plastic products can be distinguished from the touch, temperature, and hardness of the hand. Generally, it is not difficult to distinguish, so such counterfeit products are gradually scarce.

2. Glass products, this kind of seeing is clear as water, no texture, low hardness, single refractive index, mixed with air bubbles, and it is also very good Good discern.
3. The melting crystal refers to the crystal synthesized by the domestic crystal residue, like glass, but it has been made into a ball of 7 to eight centimeters to ten centimeters. Low, you can use polarizer to distinguish.
4. Crystal glass is actually "lead glass". The bowl of bowls with lead metal, the most on the market, because the refractive index and color dispersing rate are good. But it is not suitable for spiritual use. Generally, it can be judged by itself.
5. Artificial crystal, also known as "raising crystals", there is no six -way crystal crystal, which is the easiest to judge; but if it is grinded into the finished product, it is not good to judge in the above method. Ultraviolet spectrometer "can distinguish between true and false. The most on the market are colorless transparent white crystals, amethyst, yellow crystals, and water -blue crystals. It is recommended that friends, when encountering controversial crystal ore, it is best to send a fair third person, such as the appraisal office to identify and identify it. It costs not much, but there is a professional guarantee. If necessary, even the appraisal of two or more appraisals. It is best to buy "rough stones" and look at its crystal, growth patterns, and symbiotic minerals. In addition, it is the purchase of crystal ore containing "Inclusion". Most people mistakenly call impurities and flaws, which is the best proof of "growing to nature".
