[1][2] In 1996, Grayson made headlines around the world with the discovery of a blue mineral which at the time was believed to be hitherto unknown to science.
[14][16] From the late 1980s to the early 2000s, Grayson fronted many factual radio and television series covering a variety of subjects.
[3][4][5] She had purchased the rock at a roadside stall in Morocco in the early 1980s, where the seller had identified it as lapis lazuli, a relatively common blue mineral.
Whilst at a promotional photocall for The Essential Guide to Rocks, she declined the photographer's request that she pass her geological hammer to co-presenter Ray Mears, on the basis that she was the only trained geologist in the picture.
[9] For one assignment, she recreated Jan van Eyck's Arnolfini Portrait as a photographic pastiche, featuring modern-day subjects looking at their smartphones.
[28][58][59] A further four more pastiches have appeared at the Summer Exhibition, including versions of Leonardo's Mona Lisa, The Kiss by Klimt, a still life depicting fossils and rocks, and, in 2024, Rembrandt's A Woman Bathing in a Stream.
