Expert Eyes and Advanced Tools
Each diamond piece that comes into our care is assessed by our in-house team, who are trained in diamond grading and verification. Visual inspections play a key role, but our process goes far beyond the naked eye. Using specialist diamond testers, UV light analysis, and loupes, we examine cut, clarity, colour, and carat weight to determine authenticity.
Where needed, we also use advanced equipment such as electronic diamond testers, thermal conductivity probes, and sometimes even microscope analysis to confirm the diamond's origin and ensure it is naturalnot synthetic or treated.
