Many believe this black gemstone brings courage and protection. In love, black diamonds represent eternity and loyalty. Additionally, they are the birthstone for April and the gemstone for the 60th wedding anniversary.

Salt and pepper diamonds have a lower concentration, with speckled black spots and noticeable white inclusions, resembling salt and pepper, hence their name. Initially considered flawed, this black gemstone is now accepted as uniquely beautiful, and more and more people are choosing salt and pepper diamond rings as engagement rings.
