Diamonds, the birthstone for April, are renowned for their brilliance and strength. Scoring a 10 on the Mohs scale, they are the hardest natural material on Earth, making them incredibly durable and resistant to scratching.

Diamonds are made entirely of carbon, formed under extreme heat and pressure deep within the Earth’s mantle. While they are often colorless, diamonds can also appear in various shades, including yellow, blue, pink, and even red. These colors are caused by trace elements like nitrogen or boron, or structural irregularities within the diamond.

The cut of a diamond plays a crucial role in its sparkle. The round brilliant cut, with its 58 facets, is the most popular and maximizes the diamond's brilliance. Other cuts, such as princess, emerald, and cushion, each offer a unique appearance, emphasizing either brilliance or clarity.
