How to identify the quality of pearls? 20

Color is not a factor in determining the quality of a pearl.

Grasp the key points:

1. Finish.

The smoother and flawless the beads, the higher the grade. The production of pearls is actually not small, but there are fewer beads that meet this condition, and many beads can only be sold at low prices or ground to make pearl powder. However, no matter how good the beads are, they will inevitably have some very subtle growth lines, otherwise they are not natural pearls.

2. Brightness. The more reflective the beads, the higher the grade. Under the fluorescent lamp or the sun, good beads can give people a crystal clear feeling, and that kind of dull beads may not be sold at such a high price.

3. Roundness. Pearls are naturally occurring, and even every pearl cannot be exactly the same, nor can it be exactly the same like glass beads. So. The more round the bead, the higher the value.

4. Size. If the pearl meets the above conditions, if the diameter is larger, the more valuable it is, and when it touches a bead with a diameter of more than 11mm, it can also be smooth and flawless, crystal clear, which is a high-end luxury.

l) Vision: The shape of the pearl is not very regular, showing translucent jade white, yellow-white, light basket color, flesh red and other natural and unique multicolored fluorescent luster; The pseudo-beads are mostly glass imitations, with regular shape and uniform size, and are generally coated with silver powder or "glazing liquid" made of fish scales on the surface of the beads, with monotonous color and lack of halo.

2) Feel: The pearl is very refreshing, even when the weather is hot, the tentacles feel very cool; If it is a pure glass imitation bead, the specific gravity is greater than that of the pearl, and if it is a wax-filled glass imitation bead, the specific gravity is only about half of the pearl.

3) Fire: The pearl is burned on the gas lighter, the surface is intact, and the luster is still there; After the pseudo-beads are burned, the surface will appear black smoke, and the luster will be lost.

Pearl is a popular jewelry article in all countries around the world, due to the different grades and quality, the difference is very large, and the purchase can be identified from the following aspects:

1.Type According to the different generation conditions of pearls, the type is the first factor that determines the grade of pearls, in order: natural seawater beads, natural freshwater beads, seedless beads, and seeded beads (cultured pearls are also higher than freshwater beads).

2.The larger the weight (or volume), the more precious, the so-called "seven-point pearl, eight-point treasure".

3.The shape is more round, the more precious, and its quality is: fine circle, sub-circle, oval, oblate, falling, and arbitrary.

4.The color is the best in white with slightly translucent pink, and the extremely white is also the best quality, followed by pink white, light red, light yellow, cyan, etc.

5.Skin light When external light hits a pearl, the pearl light is reflected layer by layer and forms a halo is the main reason why people love pearls. The higher the skin light, the more beautiful its halo will be.

The sign of thin and smooth skin is that you can see the pupils of your own eyes in the image reflected in the smooth pearl.

6.Double pearls Among the many pearls, the color, skin light, and size are all the same into a pair of pearls, and its value is no less than that of high-grade gemstones.

7.Cladding In the case of pitted cultured beads, the thicker the nacre that is covered, the better.

8.Pearl Yellow The biggest disadvantage of pearls is that they are not durable enough, because aragonite that makes up pearls is an unstable mineral that tends to turn into another mineral, calcite. When it changes, the pearl turns yellow and loses its beautiful luster, which is called "pearl yellow is not worth anything".
