Looking back on the last five or six years could cause someone in our industry to react in a number of ways, perhaps several simultaneously! The sweeping changes and rate of technological development over the last half-decade or so can only be described as astounding.
Earlier this year, I had the opportunity to visit my daughter’s Grade 4 class to make a brief presentation on gemmology, as well as the gemstone and diamond industries. It was meant to be part of their geology studies, which they were studying at the time, and so the principle focus of my talk revolved around some of the core foundations of our industry.
Over the last 90 years, some of the most prominent gemmologists and gemmological institutions have aimed to create scientific consistency. The principal goal of their endeavour has been to formalize a standardized, unbiased language to accurately describe diamonds and gemstones.
Every professional has tools and techniques they consider indispensable to their trade. The world of gemmology and jewellery appraisal is somewhat unique in that many of us are left to figure these out for ourselves.
In the previous column, we looked at how tiny errors can add up to significant problems when dealing with many small stones. This time, we’ll look at the calculations and adjustments that might be necessary when examining diamond centre stones.
As a professional appraiser, I pride myself on accuracy, clarity, and a defensible methodology. I believe what I’m doing and how I’m doing it is ‘right.’ Recent experiences have somewhat shaken my belief system, and I thought I’d share my concerns with the hope others finding themselves in any similar situations might benefit from my learning curve.
Experience and keen perception are a must in the jewellery industry. Since the scale of the object is most often very small, this is a good place to start training the eyes to see things that can truly make a difference in value and price.
