What is a Diamond?
A diamond is a natural or lab-created gemstone made entirely of carbon. It is the hardest known natural material on Earth and is prized for its exceptional brilliance and fire.

- Composition: Aluminum oxide

White sapphires are often chosen as a more affordable alternative to diamonds, especially for those who prefer a subtle, understated look.
