F. 
Imitation pearls are of another different story. The Island of Mallorca in Spain is renowned for its 
imitation pearl industry. In most cases, a bead is dipped into a solution made from fish scales. But this 
coating is quite thin and often wears off. One way to distinguish the imitation pearls is to have a bite on it. 
Fake pearls glide through your teeth, while the layers of nacre on the real pearls feel gritty. 
 
G. 
Several factors are taken into account to evaluate a pearl: size, shape, Colour, the quality of 
surface and luster. Generally, the three types of pearls come in such order (with the value decreasing): 
natural pearls, cultured pearls and imitation pearls (which basically are worthless). For jewellers, one way to 
tell whether a pearl is natural or cultured is to send it to a gem lab and perform an X-ray on it. High-quality 
natural pearls are extremely rare. Japan’s Akoya pearls are one of the glossiest pearls out there, while the' 
south sea water of Australia is a cradle to bigger pearls.

H. 
Historically, the pearls with the highest quality around the globe are found in the Persian Gulf, 
particularly around Bahrain. These pearls have to be handharvested by divers with no advanced equipment. 
Unfortunately, when the large reserve of oil was discovered in the early 1930s, Persian Gulf’s natural 
pearl industry came to a sudden end because the contaminated water destroyed the once pristine pearls. In 
the present days, India probably has the largest stock of natural pearls. However, it is quite an irony that a 
large part of India’s slock of natural pearls are originally from Bahrain.
