Описание: This video transcript explains the scientific techniques used to differentiate between natural diamonds and those created through the High Pressure High Temperature (HPHT) method. While these stones appear identical to the unaided eye, the source details how microscopic metallic remnants from the growth process serve as a definitive chemical fingerprint for lab-grown gems. These metallic inclusions can even render a diamond magnetic, a characteristic never found in earth-mined stones. Additionally, the presence of elements like boron and nitrogen provides further evidence of a diamond's synthetic origin by altering its electrical conductivity or color. By comparing these markers against other methods like Chemical Vapor Deposition (CVD), gemologists can determine a stone's true history with total certainty. This investigation highlights how the internal composition of a diamond serves as a permanent record of its unique creation.
