The ICA GemBureau has scanned its vast collection of colored gemstone
varieties, most of which are held on 35-milimeter slides. This unique
collection is the hidden treasure of the International Colored Gemstone
The Collection consists of hundreds
of high-quality photographs of colored gemstones. The project was
started in the mid 1980s by Cheryl Kremkow, the first GemBureau
director and the first editor of the ICA gazette.
Bart Curren of Vancouver, Washington
was the photographer for most of the slides. He is a gem carver
and cutter in his own right. Bart would tour the booths of ICA members
exhibiting at the gem shows in the US, and would then choose a variety
of cut stones to photograph.
