GIA Knowledge Session: Quantifying Diamond Fluorescence

[prs]

This might be of interest to our diamond afficionados.

The subject of this week's GIA's online knowledge session is:

Quantifying Diamond Fluorescence and Its Visual Impact​

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.

The session starts at 10.00am PST this Thursday, but they always post a recording of these sessions on their YouTube channel.

Very cool - thank you for posting this, prs!

For those that are interested, here is the link to past GIA Webinars:

GIA Knowledge Sessions

GIA Knowledge Sessions, a series of talks and seminars that promise to engage participants in the most diverse and pressing issues in gemology today, including gemstone origin, laboratory-grown stones and new grounds in field gemology.

Their webinars are usually good, I've watched several live while eating lunch. I always learn things.

This paper is outstanding.

Measurement and Characterization of the Effects of Blue Fluorescence on Diamond Appearance | Gems & Gemology

Using customized, image-based measurement systems to quantify the effect of fluorescence on the color, brightness, and transparency of gem diamonds viewed in both face-up and table-down orientations.

And Luo is a shining light in GIA in my book.
She has done some great research.
some of you know that I have been telling buyers to avoid clouds and graining in fluoro diamonds.
Hopefully GIA will take her work and start grading haziness and milkyness with a proper transparency grade
