I’m currently researching an article on ruby, and came across a quote
by Dr. James B. Nelson published in the Journal of Gemmology in 1985
describing his efforts to find a quantitative description of the
colour “pigeon’s blood”.
Would anyone have the details of the article, i.e. full title of the
article, Vol. No., page, etc.?
This quote was apparently also published in Richard W. Hughes book
"Rubies and Sapphires" (ISBN 0964509768).
Any help in locating the source would be greatly
Thanks in advance! Dianne
