The identification of a dyed pearl can be simple at first sight by the nonnatural tones that usually are used, but exists confusion when observed if some of these cases takes place:

Perforated dyed pearls, they redden once the drill is done reason why the hole also is dyed. Passing a thread through its interior and rubbing it, we will know that it is dyed if it leaves rest of color in the thread (radiated pearls do not leave any rest).

Also, we can observe in a mounted necklace the color of the thread and observe if it is stained with rest of the dye.

Applying a dissolvent or acquittal enamels on dyed pearl, will make it lose its dye. Breaking the pearl, will be observed that in it's interior the color is different, the natural color will appear.

What it is not so simple to distinguish is a Natural color pearl with of Radiated one, because the difference is in the crystalline structure.+CONTINUE
