Semi-precious stones are naturally occurring minerals that are prized for their beauty, rarity, and durability. Unlike precious stones such as diamonds, rubies, sapphires, and emeralds, semi-precious stones encompass a broader range of materials including amethyst, turquoise, garnet, opal, and jade. These stones are often used in jewelry, decorative items, and in various cultural rituals. They are valued for their unique colors, patterns, and the perceived metaphysical properties they are believed to possess. Despite being termed "semi-precious," many of these stones are highly sought after and can be quite valuable.
