February 25, 2026 The Rare Rock Report Pretend you are with me and It’s April 6, 1992.

I was asked, even then as a global diamond expert, to give feedback on proposed changes to the GIA diamond grading system.

A crucial aspect of gemological investigation is the determination of gemstone treatment and provenance. However, with the growing number of treatment methods and synthetic materials, analytical facilities must engage more precise equipment to analyse the chemical composition. Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry (LA-ICP-MS) has been widely used for decades in the fields of geology, chemistry, material science, and biology.

I’ve seen this icky scam online and just want to spread the message that lab grown is not explicitly synonymous with diamond even if it is often used that way. Make sure to get a certificate from a reputable third party Gemological institute like the IGI or GIA. All of our diamonds are certified, always.
