Lab Grown (read more)
Lab-grown diamonds are real diamonds that are produced in a controlled environment. These diamonds are created by replicating the conditions under which natural diamonds are formed, typically through two primary methods: High-Pressure High-Temperature (HPHT) and Chemical Vapor Deposition (CVD).
- High-Pressure High-Temperature (HPHT): In this method, a small diamond seed is exposed to extremely high pressure and high temperature to stimulate the growth of a larger diamond around the seed.
- Chemical Vapor Deposition (CVD): CVD involves introducing a carbon-containing gas into a chamber where carbon atoms adhere to a diamond seed, allowing the diamond to grow layer by layer.
Both HPHT and CVD diamonds have the same chemical and physical properties as natural diamonds. The choice between the two methods depends on factors such as cost, desired specifications, and laboratory capabilities.
Lab-grown diamonds vs natural diamonds
- Lab-grown diamonds exhibit the same physical, chemical, and optical characteristics as natural diamonds.
- They display the same fire, scintillation, and sparkle as natural diamonds.
- Lab-grown diamonds are nearly impossible to differentiate from natural diamonds using a jewelry loupe.
- They may have different trace elements than natural diamonds, but it does not affect their appearance.
- Distinguishing lab-grown diamonds from natural diamonds requires specialized equipment.
- Authentic lab-grown diamonds come with a gem certification identifying them as laboratory grown.
- Cost effective
Lab-grown diamonds and natural diamonds share identical chemical compositions and are assessed using the same universally accepted standards. The evaluation process, conducted by skilled gemologists, revolves around the "Four C's": Cut, Color, Clarity, and Carat. For both lab-grown and natural diamonds, each diamond undergoes individual grading, meticulously scrutinized in terms of its cut, color, clarity, and carat weight. Subsequently, these grades for the Four C's are consolidated to ascertain the overall final grade of the diamond. This systematic grading approach ensures consistency and fairness in assessing the quality and value of both lab-grown and natural diamonds.
