If the naked eye can't see ice cracks, blemishes, black spots, mines, etc., it can be regarded as a completely clean garnet. If you look carefully, you can still see some cotton wool, but there can be no ice cracks and obvious black spots.
Observing under a magnifying glass, the cotton wool is still quite obvious.
Let's start with a few pictures of completely clean garnet. Of course, there are very few such garnets, and the price is of course high. I will analyze it in depth later. Teach you the key points of appraisal, master them, and feel free to buy them in buy buy.
The quality of garnet can be comprehensively evaluated from the following seven dimensions, and the indexes such as ice crack, black spots and cotton wool need to be observed under the lamp for the complete net observation:
1, color: The common colors of pearl garnet are wine red, orange red, rose red and rose purple. On the premise of the same quality, the price of rose red and rose purple will be higher, while the value of Brazilian rose purple material is higher. Note that the color of natural light is closer to the real color. This is like seeing who has a good complexion and a good complexion, which is naturally more popular.
Different colors, big price gap.
2, ice crack: there are very few garnet without ice crack, and the natural value is higher. Garnet with more ice crack may often have glue residue, which is not suitable for personal wear. For example, it is not recommended to choose on the right side of the following picture. This is like a scar on the face. If there is a scar, the face value will naturally be affected.
The more ice cracks, the lower the price.
3. Miscellaneous points: It is extremely difficult for natural gemstones to be completely free of impurities. The value of defects is almost invisible to the naked eye, and more black spots indicate that the material is impure. This is also like a spot on the face, which everyone doesn't want to see.
Less miscellaneous points, crystal clear, pure and flawless are more popular.
4. Cotton wadding: Cotton wadding is formed because there are tiny gaps or impurities inside, which affects its permeability. The more transparent and clear it is, the denser and purer the structure is. It's better to look foggy than crystal clear. It's always a pity if it's not clear.
Clear value is higher.
5. Size: On the premise of the same quality, the bigger and rarer the beads, the higher the gram price of the beads. The price of beads is much lower. The more natural it is, the rarer it is, and the rarer it is.
With the same quality, the bigger the beads, the rarer they are, and the rarer things are more expensive.
6, workmanship: good round beads, the skin should be complete, the bead shape is round, and the pit is extremely fine. In addition to the skin, the serial orifice grinding can better reflect the workmanship. Just like make-up, make-up is exquisite and natural, which is more lovable.
7. starlight benefit: starlight effect is a special optical effect in gemstones. Under the same quality, the value of starlight effect is higher, and the value of starlight with six shots is higher than that of starlight with four shots.
Through the comprehensive appreciation of the above seven dimensions, it is not difficult to see that the higher the face value, the higher the value, and the axiom that "things are rare" is also universal on garnet.
