Quantifying Diamond Fluorescence and Its Visual Impact | GIA Knowledge Sessions Webinar Series

GIA Knowledge Sessions Webinar - recorded live on December 16, 2021.
The impact that fluorescence has on a diamond’s appearance has long been a hot topic of debate. A team of GIA scientists recently embarked on a study to quantify the relationship between the intensity of a diamond’s blue fluorescence and its effect on face-up and table-down color, brightness, and transparency. Follow GIA Director of Metrology and Quality Control Dr. Yun Luo as she uncovers the GIA team’s latest discoveries.

Glad these knowledge sessions are still going. Love these, so informative!

Personally I love diamonds with strong fl as long as they are VS1 or higher in clarity and D in color, then the fluorescence gives them extra shine and makes the diamond appear more colorless. I think it is similar to for instance washing powder for white clothes where they ad a very small amount of blue to the powder, this makes the white clothes appear more white. Painters do the same thing with white paint for the ceiling, they ad a tiny drop of blue paint to the white paint. This will create an illlusion of an extra white ceiling and makes a room appear higher then it is.

Excellent video. Spectroscopy had evolved greatly in gemology & metal (gold specifically) purity (x-ray) recently. Bravo!

Fascinating webinar- can not believe I have not watched this one before. #timetofluoresce

What about the strong yellow fluorescence effect in Type Ia 480nm orange diamonds? It seems to be a positive thing coz it makes it look more orange?
