Synthetic diamonds, also known as lab-grown diamonds, are created in controlled environments using advanced technology. They have the same physical, chemical, and optical properties as natural diamonds, making them virtually indistinguishable from their mined counterparts. These diamonds are produced through two main methods: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). Both processes replicate the natural conditions under which diamonds form, allowing for the creation of stones that are often more affordable and environmentally friendly than traditional diamonds.
