A natural stone necklace is a piece of jewelry featuring gemstones that are mined and shaped from naturally occurring minerals. These stones are often valued for their beauty, rarity, and unique patterns. Each necklace can include various types of stones such as quartz, turquoise, amethyst, or jasper, and they may be polished, faceted, or left in their raw form. Natural stone necklaces are prized for their aesthetic appeal and believed metaphysical properties, making them a popular choice for both fashion and spiritual purposes.
