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. These diamonds are produced through two main methods: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). Unlike natural diamonds, which form over millions of years deep within the Earth, synthetic diamonds can be made in a matter of weeks. They are often more affordable and environmentally friendly, as their production reduces the need for mining. Synthetic diamonds are gaining popularity in the jewelry market for their ethical and sustainable attributes.
