Correcting The Wrong Cleaning Pearl Methods

Someone told me that use the toothpaste to brush the pearl surface can make it to be as bright as a new one. However, it is not an ideal way to do so. The toothpaste contains a high micro-hardness abrasive particulate matter, which is particularly small but hard (almost as hard as the crystal). That's to say, the method of cleaning jewelry by toothpaste will damage the surface which hardness is lower than the crystal, such as the surface of pearl, gold and K gold. The correct cleaning solution of pearls should be use the neutral-active agent (such as baby shampoo). I had made a detailed introduction about it in previous article How to Recover Pearl's Nature Gloss.

The Correct Diameter Measure of Pearls

As the popular saying goes, those pearls with a diameter less that 7mm are just beads, while those with more than 8mm are the right precious treasures. 7mm to 9mm pearls are the most popular ones, it is hard to abtain 10mm-pearl, not to mention those South Sea pearl and the Black pearl with a 11mm diameter.


It is hard and unscientific to define a pearl's diameter just by our eyes. The precise figuure should be measured by a professional measure tool -- Disc Vernier caliper. Measure three times and write down the average maximum diameter and the average minimum diameter.


There are different ways to show the diameter of the different pearls. Use the minimum diameter for those perfectly round, round and off-round pearls, and both maximum and minimum diameter for other shape pearls, like oval, drop and baroque pearls. E.g. A round pearl's diameter is 6.0mm, and a oval pearl's is 6.0 - 7.5mm.

How to Tell If a Tahitian Black Pearl’s Color Is Dyed or Natural

Tahitian Pearls are cultured in French Polynesia. Because of its natural black color, they are also called black pearls. Tahitian Pearls are very valuable due to the level of complication involved in their production. Because the “right black” color is not always smoothly obtained, some of them need to be dyed to be “right”. The value of dyed black pearls is much lower than the natural black pearls. It is common for speculators to mix up dyed black pearls, even freshwater or fake pearls, with natural black pearls.

Here are some tips for how to differentiate natural or dyed black pearls.

Tahitian Pearls tend to not only have one single color of overtone. The multi-overtone is called “rainbow” or “peacock”. Overtones vary between individual pearls. The dyed black pearls tend to not have other colors of overtone but black. If the color around the pearl hole or blemish area is darker than the body color, then it is a dyed pearl.
