A pearl necklace's weight varies significantly by pearl size, type, and strand length, but expect a standard 16-18 inch freshwater necklace to weigh roughly 20-50 grams, while larger South Sea pearl strands can easily top 100 grams or more, with the weight coming from the pearls themselves and the metal clasp. Real pearls feel substantial, like pebbles, unlike lighter plastic fakes.
For comparison a natural pearl of 2.72 specific gravity and a 10 millimeters diameter would weigh 28.37 pearl grains; a cultured pearl of 2.75 specific gravity and a diameter of 10 millimeters would weigh 28.69 pearl grains.
Real pearl necklace prices vary wildly, from under $100 for basic freshwater strands to tens of thousands for rare, high-quality South Sea or Akoya pearls, depending heavily on pearl type (Freshwater, Akoya, Tahitian, South Sea), size, luster, shape (round is pricier), color, and quality (AAA+ vs. lower grades). Expect budget options around $100-$300 (freshwater), mid-range at $300-$2,500 (Akoya, good Tahitian), and fine quality (South Sea, Hanadama Akoya) from several thousand to over $10,000.
Most real pearls feel somewhat heavy for their size, while fakes (especially plastic pearls) will have a light, insubstantial feel.
It was Jackie Kennedy who said 'pearls are always appropriate,' meaning that they suit all occasions and all outfits. Indeed pearls are still worn by many brides on their wedding days and feature in most jewellers' windows today.
The most expensive pearl colors are often deep, rich hues like Golden South Sea (especially 24k deep gold), rare Peacock Tahitian (dark green/blue/purple overtones), and intensely pink or pink-overtoned White South Sea pearls, with value heavily depending on rarity, luster, size, and lack of blemishes, rather than just the base color itself. While white and black are common, specific, saturated, and rare overtones within these categories command the highest prices.
If you store your pearls in airtight containers or in plastic bags, they won't be able to breathe and are more likely to dehydrate and go yellow. Store your pearls in unbleached cotton, silk, velvet, or Chamois leather. These materials retain moisture from the air, reducing the likelihood of dehydration.
Some pearls have an astronomical resale value in the auction market. These have included pearls with historical significance, pearls who have belonged to famous people, pearls from unique areas, natural and rare pearls and more.
In water, pearls do not float.
Pearls below 7mm in size are considered to be on the smaller side, while 7-8mm and 8-9mm are among the more popular sizes selected for necklaces in Freshwater pearls. Anything sized from 9-10mm and above is considered to be above average in size, and such pearls are more rare and valuable.
What is the basis for the unit "chow" / "Chav" for pearls? The formula for calculating the "chav" per carat involves squaring the carat weight (multiplying the carat weight by itself), and multiplying that by 0.6518.

Can Yellowed Pearls Be Whitened? Yes, but only gently and gradually. Pearls that have gone yellow over time can sometimes be lightened with careful cleaning. Use a soft cloth and mild soap solution — never bleach, baking soda, or vinegar, as they will damage the nacre.
Pearls that have not been taken care of properly will deteriorate over time. Here's some tips for keeping pearls looking their best. This 26" strand of 10mm freshwater pearls was most likely put on before applying makeup and hair products, was never cleaned after wearing, and was never stored properly.
Pearls should never be cleaned in an ultrasonic or steam cleaner. It's safe to use warm, soapy water for occasional, thorough cleaning. If the pearls are strung, be sure the string is completely dry before wearing. For routine care, it's best to wipe cultured pearls with a very soft, clean cloth after each wearing.
The qualities that determine the overall value of a natural or cultured pearl or a piece of pearl jewelry are size, shape, color, luster, surface quality, nacre quality, and—for jewelry with two or more pearls—matching.
Natural Black pearls (uncultivated) are extremely rare and are found in about 1 in every 10,000 oysters. In an effort to preserve the species, it is illegal to dive to find natural pearls.
The type of pearl significantly impacts its price. South Sea and Tahitian pearl are the most expensive since they are rare and of great grade. Akoya pearl, known for their perfect round shape and outstanding beauty, are next. Freshwater pearl are the cheapest since they are wide in variety.
