Why are pearls different colors?
The color of a pearl depends on the Oysters environment.Most pearls are white, sometimes with a creamy or pinkish tinge, but may be tinted with yellow, green, blue, brown, or black.The unique luster, or orient, of pearls depends upon the reflection and refraction of light from the translucent layers and is finer in proportion as the layers are thinner and more numerous. The iridescence which some pearls display is caused by the overlapping of successive layers, which breaks up light falling on the surface.South sea pearls are the color of their host oyster's mantle - and can be white, silver, pink, gold, cream, and any combination of these basic colors, including overtones of the various colors of the rainbow displayed in the pearl nacre of the oyster body itself.Additional Information While the environment is a factor in a pearl's color it is a limited factor. The strongest defining factor is the type of mollusk. Different pearl mollusks produce different color for different reasons. South Sea PearlsSouth Sea pearls are produced by the Pinctada maximamollusk. There are two common varieties used in perliculture. The first is the silver-lip and the second is the gold lip. These colors refer to the the color of the mantle and the mother-of-pearl (nacre) which the mantle produces. The silver-lip is responsible for producing white, silver and white with rose overtone South Sea pearls while the gold-lip produces gold, yellow and champagne pearls. Of the two varieties, deep golden South Sea pearls are the most valuable, considered the most valuable cultured pearls in the world. Tahitian Pearls of Black South Sea pearlsThese are pearls produced by the Pinctada margaritiferamollusk, otherwise known as the black-lip. Similar to pearls produced by the Pinctada maxima, the color is determined by the mantle color, specifically the color of the donor mantle tissue used in the grafting operation. Freshwater PearlsFreshwater pearls come in a variety of natural colors. The colors are due to a myriad of reasons including but not limited to; the environment, the type of mussel used (Hyriopsis cumingii, Hyriosis schlegeli or Cristaria plicata), and the location of the graft within the host mussel's mantle tissue. Aniline Organic Dyes, Cobalt-60 Irradiation and HeatSome pearls are treated to attain their colors. Many freshwater pearls are dyed in fancy bright colors, and many freshwater and akoya pearls are dyed dark. The dyes are aniline organic. Cobalt-60 radiation is also used to alter the validity of the manganese content in freshwater pearls and akoya pearl nuclei. Manganese is only present in freshwater mussel shell. It will darken freshwater pearls and darken akoya pearl nuclei which is composed of freshwater mussel shell. This will produce a dark, gray effect.Heat is also used, primarily in Tahitian pearls, to attain the currently popular chocolate coloration.

Are white or black pearls more valuable?
Answer There is no simple answer to this question as it really depends on the type of pearl you are discussing. The most common types of pearls are cultured akoya and cultured freshwater. Neither of these are naturally produced in a black coloration. Black akoya and freshwater attain their coloration from aniline organic dyes or cobalt-60 irradiation. Natural black pearls are known as black South Sea, Tahitian or Cook Island pearls. They are produced by the Pinctada margaritifera black-lip mollusk. These naturally black pearls grow quite large are are typically more valuable than akoya or freshwater pearls. The most valuable of all pearls are those grown in the Pinctada maxima or silver and gold-lip mollusk. These pearls are usually very larger and expensive, and come in colors of white, white with pink overtone, champagne, silver, yellow and gold.

Pearl Jewelry Is A Classic Gift?
Pearl jewelry has been given as gifts and worn with pride since the first pearls were fished out of the oceans. Today, pearl jewelry made from saltwater pearls from the South Pacific are the most prized, while freshwater pearls are also sold at more affordable price points. While saltwater pearls are most valuable due to their uniformly round shape, freshwater pearls often are more irregularly shaped. These freshwater pearls often are oblong, flat, or even rectangular. The most classic piece of pearl jewelry is the string of white pearls, formed into a necklace. Pearl necklaces are considered an appropriate gift for a woman upon graduation from college, engagement to be married, or for her wedding. Pearl necklaces are worn proudly for years, before being passed down as heirloom items to the next generation of daughters or granddaughters. Pearl necklaces may need to be restrung after being worn for a decade or two, however the pearls themselves should not be cleaned with chemical jewelry cleaners. These cleaners, while appropriate for other types of jewelry, which is made of metal or hard gemstones, are abrasive on the soft surfaces of pearl jewelry. When pearl jewelry is worn, however, the natural oils from the woman's skin enhance the beauty of the pearl jewelry. To avoid deteriorating the beautiful natural finish on pearl jewelry, women should not wear perfumes or other fragrances on their skin when they are wearing pearl jewelry. While white pearl necklaces are the most commonly purchased pieces of pearl jewelry, black Tahitian pearls are also very beautiful. Black Tahitian pearls may be worked into a piece of pearl jewelry on their own, such as a black Tahitian pearl necklace or bracelet, or they may be combined with white pearls for a striking patterned piece of pearl jewelry. Other colors of pearls are even more rare, however they are considered very beautiful and valuable. Freshwater pearls, such as the oblong teeth pearls, oval shaped seed pearls and chunky potato pearls, come in a wide variety of colors and sizes. While they may not qualify as fine jewelry like their saltwater pearl cousins, these freshwater pearls are used by jewelers to create beautiful pearl jewelry.

Pearl Necklaces Offer Chic Elegance?
For many women, the goal of donning a piece of jewelry is not to call attention to the piece of jewelry itself. Rather, the goal of putting on a necklace of pair of earrings is to enhance their overall appearance. Pearl necklaces have long been prized by women for doing just that. They enhance a woman's professional appearance, whether she is wearing a school teacher's blouse and skirt, or an attorney's formal business suit. Women may purchase a traditional pearl necklace, consisting of a string of matched white pearls, from a variety of small, independently owned jewelers, large chain jewelry stores which may be found in malls, and in department stores. While pearl necklaces are thought of as being uniformly strings of matched white pearls, the length, size of the pearls strung on the necklace, and the enhancer or other fastener will vary the price. Different retailers may offer a variety of different options in this regard. The price of a pearl necklace is dependent upon both the number of pearls that the pearl necklace contains, as well as the size and quality of those pearls. Pearls which are whiter are considered more valuable than those pearls which are a more yellowed hue. While larger pearls may be worth more, it is possible for smaller pearls to be considered more valuable, as larger pearls are more likely to have defects or other impurities which will devalue the pearl necklace they are strung upon. Pearl necklaces are most likely sold with a string of white pearls, however they may also be sold as a tripe strand, or even an extra long single strand of pearls. The extra long single strand of matched pearls may then be looped twice or even three times around the wearers neck, for a custom length necklace which can be adjusted based on the outfit. Pearl necklaces also may be made from a string of Tahitian black pearls, which are more rare than white pearls, or freshwater pearls, which are available in a variety of colors. Freshwater pearl necklaces will cost less, since the pearls are likely to be slightly different sizes and shapes, and they are more commonly found.
How many different colored natural pearls are there?

Were the pearls Juliette Gordon Low sold black or white?
It is most likely that the pearls were white as black pearls are very rare and expensive. Juliette's pearls were so valuable because they were matched: matched pearls means that the pearls "fit together" in a pleasing manner, and that variations among them are either minimal, gradual, or for a specific purpose.
