Q: How have major gemological institutions, such as International Gemological Institute, adapted to certifying LGDs?
A: IGI, which is the world’s second-largest independent certification and accreditation services provider, has proactively developed specialized technology to authenticate and identify the origin of diamonds. IGI, a first mover in LGD certification since early 2000s, holds approximately 65% market share in this segment, and has broadened its grading criteria to ensure accurate assessments of attributes such as clarity, cut, colour, and carat weight.
Q: What technologies and methods are used to distinguish LGDs from natural ones during certification?
A: IGI laboratories are well-equipped with advanced instruments that apply technologies, such as Raman spectroscopy, Fournier Transform Infrared Spectroscopy, and photoluminescence imaging, to distinguish LGDs from natural diamonds. We are even able to meticulously screen parcels of extremely small diamonds (known as stars and melee diamonds) using sophisticated bulk screening equipment for the presence of LGDs. Our stringent testing protocols ensure reliable results, reinforcing consumer confidence in the authenticity and quality of their diamonds.
Q: How has LGD certification impacted consumer trust, and the broader jewellery market?
A: The certification of LGDs has significantly bolstered consumer trust within the jewellery market by providing authenticity and transparency regarding the origin and quality of diamonds. This has fostered greater acceptance of LGDs, enriching the diversity of the jewellery market, and making fine jewellery accessible to a broader audience. As LGDs gain traction, IGI has been ahead of the curve, and invested in R&D, to make sure our grading techniques are evolving too to ensure the accurate grading and identification of fancy shapes and fancy coloured LGDs.
