Diamond Meaning and History
The word diamond comes from the Greek adamas, meaning "invincible" or "unbreakable." Diamonds were first mined in India more than 2,000 years ago, where they were prized as talismans and symbols of power. Brazil became a major source in the 1700s, and the discovery of diamonds near Kimberley, South Africa, in the late 1860s transformed the diamond trade.
The first recorded diamond engagement ring was given in 1477, when Archduke Maximilian of Austria proposed to Mary of Burgundy. Since then, the diamond has become the world's most recognized symbol of lasting love.

The 4Cs of Diamond Quality
- Cut is how well a diamond's facets reflect light. It has the biggest effect on sparkle.
- Color measures how colorless a white diamond is, from D to Z.
- Clarity grades internal inclusions and surface blemishes, from Flawless to Included.
- Carat is the diamond's weight. One carat equals 0.2 grams.

Lab-Grown vs Natural Diamonds
Lab-grown diamonds are real diamonds. They have the same chemical composition, crystal structure, hardness, and sparkle as mined diamonds, and they can only be told apart with specialized lab equipment. The difference is origin: lab-grown diamonds are created in weeks using high pressure and high temperature (HPHT) or chemical vapor deposition (CVD), rather than forming over billions of years underground.
Lab-grown diamonds typically cost far less than natural diamonds of the same size and quality, which lets couples choose a larger or higher-quality stone for the same budget. They are graded by labs such as IGI, and in October 2025 GIA moved to a simplified two-tier grading system for lab-grown diamonds. For a deeper comparison, read:

How to Care for Diamond Jewelry
- Clean regularly with warm water, mild soap, and a soft brush. Diamonds attract skin oils and lotion, which dull their sparkle.
- Ultrasonic cleaners are usually safe for diamonds without fractures or treatments, but check with a jeweler for fracture-filled stones.
- Store separately. Diamonds can scratch other gems and even other diamonds.
- Have prongs checked once a year. Diamonds are hard but can still chip from a sharp blow, and worn prongs can loosen stones.
