Green Diamond Introduction
The formation of natural green diamonds is quite unique compared to other colored diamonds. Their green color results from the diamond being exposed to natural radioactive elements like uranium and nickel deep within the Earth's crust. This exposure causes alterations in the diamond's crystal structure, enabling it to absorb and reflect green light.
Lab-grown green diamonds, on the other hand, are created in a laboratory through irradiation and heat treatment, replicating the natural formation process of green diamonds. These treatments produce the same optical properties as natural green diamonds, allowing lab-grown green diamonds to exhibit a vivid green hue.
FAQs About Lab Grown Fancy Colored Diamonds
Q1. Are all cultured diamonds standardized in terms of color?
A: Many customers misunderstand that lab grown fancy colored diamonds, being grown under controlled conditions, have perfect color control and standardization. This is not correct. Cultured diamonds grow naturally in a synthetic environment, so each diamond is unique. Finding a cultured diamond with pure color requires large amount of luck.
Q2. Should we be concerned about fluorescence in cultured diamonds?
While most people pay attention to fluorescence when purchasing diamonds (colorless diamonds), considering it as a factor that may lower their value, but when it comes to colored diamonds, fluorescence can sometimes be a positive attribute. Colored diamonds with fluorescence are often valued more because the fluorescence enhances the color's saturation. Therefore, diamonds with fluorescence can even be more popular in some cases.
