When it comes to South Sea pearl beads, these are small, rounded, or semi-rounded pearls that have been drilled to allow for stringing. They are often used in jewellery-making, including necklaces, bracelets, and earrings. The beads can be uniform in size for a classic and symmetrical look, or they can be graduated in size for a more contemporary and dynamic design. It is important to consider factors such as size, shape, color, surface quality, and lustre. The surface quality should be relatively clean, without significant blemishes or imperfections, and the lustre should be bright and reflective. South Sea pearl beads are often used in high-end jewellery pieces due to their rarity and beauty, making them a symbol of luxury and sophistication.
