Avoid contact with perfumes,pandora charmcosmetics, acidic and alkaline substances.
Do not take a bath with a pearl, because the high temperature hot water will affect the luster of the pearl.
Not wear pearlsbead ukwith silk wrap, put in the jewelry box, to avoid the perfect object friction, collision.

5 pearl color is very beautiful, but can notcharm bracelet charmsstand the test of time. Usually after several decades, the Pearl will become the common yellow, lose their beautiful luster, which is become old, "the saying goes. Pearl turn yellow after some remedy: soaking with dilute hydrochloric acid, melted yellowingilovebeadsof the shell, the pearl to reproduce crystal clear, brilliant, charming luster color. However, if the yellow color, badly, is difficult to reverse.
Workmanship aspects: top priority in the pearl to match the material and pearl with the degree. Carefully, then, the size of the holes also affect the price of one of the factors.
7 Size: the size of the beads is a major factor affecting pricing for a whole string necklace, pearl in color and size can be uniformly and proportionate, is even more rare; so difficult to understand why a whole string pearl necklace can be reached astronomical.

Middle East, India hi, round,pandora charmround flat, Europe and the United States-based m-shaped favorite flat block-shaped. The most popular pearl jewelry pearl necklace. International color preferences of each of the various countries of pearls, the United States hi white, cream, pink, gold,bead ukblack; Italy hi EC, pink; France hi white; hi EC, UK, pink, white, gold; Hong Kong hi red, white yellow; hi EC, India, gold, blue; Canada hi white.

Pricing on a necklace, an additional factor to consider is the composition of theilovebeadspearl of the necklace with the mixed products. For the same% of yards of pearls, each of these factors, the appropriate price is as follows: 40% of the pearl luster, cleanliness 20%, 20% color 20%, shape, determine the quality of freshwater aquaculture, several additional factors in the straight role. Because freshwater cultured pearls in various shapes popular decision determining the code is a trick thing. Therefore, the weight is bound instead of determining the code. Water beads if they are equal weight in determining their quality, luster is an important factor.

In order to determine thepandora charmsvalue of a pearl, we must consider the following factors: Determine the price of an important factor in determining the code, some of the pearls of the same PCT code, valued for their quality and it needs to. The most important valuePandora beadsfactor is the luster of the pearl.
The luster of pearls is determined by the depth of the nacre, as well as crystal perfect combination to be confused with the luster of the pearl surface with its luster. Gloss is the luster of a pearl deep inside.
The pearl in a dark place, this gloss will besilver charmseasily apparent. The so-called Oriental Pearl (ORIENTALPEARLS also referred to as "special luster of pearls"), not because they are from the East, but because of the gloss sake.
No matter what grade are produced, what kind of shape and color, have acharms braceletspearl gloss, that’s for sure, if the pearl without luster, will be non-life products, general farming for a long time luster would have been better. The second factor is the pearl surface blemishes and imperfect. , Perfect pearl is quite rare, that the naked eye can see the perfect degree, determine the value of the pearl.
Color is another factor, but it is a very subjective factor. The rainbow colors or the color of the reflected light is preferred by most experts. With pink or white pearl in the United States is the most valuable. In Europe, is considered the most valuable is the cream, pink pearl, and in South America, Central America, people like a dark golden color of pearls, but the general preference for jade white pearls and more, accounting for 85% of the number of decision or more.
Pearl may be popular in many attractive shapes, but those closest to the round pearls are the most valuable. Since the since the advent of the freshwater pearl, freshwater pearl shape requirements less strict, pearl color, luster pay attention to more.

Yuhua agate alexandrite. Some agate stone with special optical properties,pandora salethere are special effects – flash, especially clear and obvious in the polished surface. When the rotation of its glossy, to see one or more of the black shadow swimming flash. Flash mobile with the visual changes, changes when the width is narrow. The numberpandora beadsof flashing lights (ribbon turn) are often associated with the composition of agate, the number of ribbon intersection. The intersection of the number of the ribbon bar resembles the flash. Flash only one in the line of intersection of the two ribbon, in any case turn, changepandora charmsdirection or perspective, the flash strip will not run out of the line outside the scope of the two intersection. Observed under the polarizing microscope, the ribbon of the twists and turns at the junction of the ribbon is a small crack, the crack on both sides of the ribbonpandora Australiathrough the cracks together. Fibrous chalcedony and particle-like chalcedony with a ribbon for the rules of the vertical ribbon arranged its minerals arranged parallel to each other and intersect at an angle with the crack. In the cracks on both sides of the ribbon and minerals, and the angle of the crack is equal. Flash the clarity of the ribbon width, ribbon and more narrow (small), the higher the clarity; ribbon width is greater than 1 mm or more when the ribbon width is greater than 0.7 mm, the flash is not clear; flash phenomenon will disappear. In addition, if the same ribbon color, flash is clear; the contrary, the different colors of ribbon, the flash is not obvious. Produce flash is caused by the refraction of light. This "flash" the efficacy of agate Yuhua agate, both of himself and a few stone Friends of the collections, turn the stone surface against the light, flashing at the light and shade, large or small, is indeed a wonderful sense of. If you have a stone, the flash at the stripes, constitute the elephant nose, as if an elephant in the absorbent to produce dynamic. Therefore, some people call it as "change stone". Of course, this agate alexandrite, opal and gem-like stone, opal, Alexander stone, such as flash color change stone. However, both types of "change stone" are the results of the optical effect. The difference is that the gem is to change the color agate opacities.

Factors affecting the alexandrite prices alexandrite color effect, size, transparency, and defects. In general, the color effect is more obvious, such as during the day was bright green, bright red at night, the higher the price. Under normal circumstances, with this apparent discoloration effect of rare gems, generally during the day was dark green, night reddish brown during the day like green tourmaline in the evening like a pomegranate red.
Change the size of the stone, the large particles alexandrite less, and thus more valuable.
Generally speaking, tablets, high transparency and less defects change the stone, its high price. International quality alexandrite price up to $ 1000-5000 per carat. The evaluation of the general chrysoberyl is often also the beautiful color and particle size of defects, how much factors.
