Fancy Color Research Foundation launches in-depth online training course for retailers
The Fancy Color Research Foundation (FCRF) has launched an in-depth online training course for retailers to guide them toward successful colored-diamond sales.
The “Winning Strategies for Color Diamond Professionals” classes will begin next week, the organization said Tuesday. The sessions cover the Interdisciplinary Unit (IDU) grading standard, used to assess a color diamond’s beauty. Participants will also learn about the three visual factors that influence value and their use in sales conversations, as well as how to discuss rarity using precise terminology, interpret a diamond’s price history, and assess the visual presence of a colored diamond relative to colorless stones.
The free master classes are on-demand sessions that currently include 14 episodes. They are available to all professionals.

Motorsport Meets High Jewellery: Hannah St John Turns Heads with ‘La Velocita’ Diamond Necklace at F1 Event
A 25-carat, 1,800-diamond Masterpiece Inspired by Formula 1 circuits Takes Centre Stage at the Glamour on the Grid ahead of the Australian Grand Prix
At the glamorous lead-up to the Australian Grand Prix, Hannah St John, partner of Liam Lawson, made a striking statement at the Glamour on the Grid event with a one-of-a-kind diamond necklace that seamlessly blended motorsport and haute jewellery.
Titled “La Velocit” (The Speed), the necklace was crafted by Australian atelier Martin Rogers Jewellery. The extraordinary piece features approximately 1,800 diamonds totalling 25 carats, intricately arranged to trace the outlines of iconic Formula 1 circuits from the global racing calendar.



A true testament to craftsmanship, the necklace required an estimated 250–300 hours of meticulous handwork, including weeks dedicated solely to precision diamond setting. Valued at around AUD $500,000 (approximately $350,000 USD), the piece stands as a bold fusion of speed, design, and luxury artistry.
Blurring the lines between engineering inspiration and fine jewellery, “La Velocità” captured attention across the paddock, proving that Formula 1’s influence extends far beyond the track.
