Pastel gemstones are precious and semi-precious stones that exhibit soft, muted colors. These colors often include light shades of pink, blue, green, and lavender, making them popular choices for jewelry. The gentle hues are typically a result of lower saturation levels in the gemstone's color, which gives them a delicate appearance. Some common examples of pastel gemstones include rose quartz, aquamarine, and amethyst. These stones are often used in various types of jewelry, such as rings, necklaces, and earrings, appealing to those who prefer a subtle and elegant look. Their unique colors can complement a wide range of styles and outfits.
