Opal Stone Glossary

Opal is prized for its unique play-of-color, displaying flashes of iridescent hues that make each bead distinct. As a relatively soft gemstone, opal requires careful handling in jewelry design. Dakota Stones offers natural opal beads that showcase a range of pastel to vivid colors, making them suitable for statement pieces or delicate accents. Designers should note opal's sensitivity to impact, chemicals, and sudden temperature changes, which can affect durability and appearance.
