What Are Lab-Grown Diamonds?
Lab-grown diamonds (also known as man-made, synthetic, or cultured diamonds) are created in a controlled laboratory environment using advanced technology that replicates the natural diamond formation process.
✅ Same chemical, physical, and optical properties as natural diamonds

✅ Can be certified by leading gemological labs like GIA and IGI

Natural diamonds are formed 1–3 billion years ago under high pressure and temperature deep within the Earth’s mantle. They are brought to the surface through volcanic eruptions and then mined.
✅ Earth-created and rare
✅ Often comes with a rich history and emotional value
✅ Require careful mining and ethical sourcing practices
