Majorca Pearls are not formed in mollusks but are man-made. Fire is used by hand to create a nucleus of glass on a revolving wire thread. This technique requires years of training and great precision. The nuclei are then dipped into a special pearly liquid, hemage, an adhesive paste made of oil and ground fish scales or mother-of-pearl, for iridescence.
The coated nuclei are then dried and polished by hand to remove imperfections such as bumps and blemishes. This coating process is repeated until a multitude of fine layers is formed over the nuclei, building up the density, hardness, and color uniformity. To assure durability, the formed blended multiple layers are subjected to various proprietary processes that make the pearls impervious to discoloration, chipping, and peeling.
Yes, there are knots between each pearl. Due to the high quality of the pearls, they are strung on silk thread, and between each pearl, a small knot is tied. This is done to avoid friction between the pearls. Also, knotting increases the strength and flexibility of the strand and the security of the individual pearls.
