Pearls come in eight basic shapes: round, semi-round, button, drop, pear, oval, baroque, and circled. Perfectly round pearls are the rarest and most valuable shape. Semi-rounds are also used in necklaces or in pieces where the shape of the pearl can be disguised to look like it is a perfectly round pearl. Button pearls are like a slightly flattened round pearl and can also make a necklace, but are more often used in single pendants or earrings where the back half of the pearl is covered, making it look like a larger, rounder pearl.
By far, three basic trends can be observed from an overview of the development of fashion design of pearl jewelry. They are clear and succinct style, returning to nature and traditional decoration.
Clear and succinct style
pearl jewelry of simple, clear and succinct tone is gaining increasing favor from customers. This because a sentiment of pursuing the inner beauty and the meaning of matter is set to people again, and need to express by simplified form. Then streamline and geometric figures from great architectural works like pyramid, marble buildings, arch bridges and so on just bring out such sort of simple style.
Returning to Nature
Urban dwellers are search of the tranquility of nature in their ideal life. This can be reflected in the way they choose a pearl jewelry. Due to the rapid development of urbanization, metals, concrete and plastics now characterize a modern city. The hectic, artificial city seems to be cold and lifeless in people's eyes of its inhabitants.
Since pearl jewellery products are thought to be works of fine arts and crafts, some traditional artistic features have been frequently employed to express memorization or yearning in design ideas of pearl jewelry. It is important that they are made to reproduce or reflect the images of ancient Roman relics, Gothic buildings, Chinese carved stone arch bridges, prehistoric totems and even the motives of primitive people in Stone Age.
