Table is missing radiation type[edit]

The color-change table in the article is great, but incomplete: it does not list the type of radiation used to accomplish the change. There are three different kinds of radiation treatment – bombardment with neutrons, electrons (beta radiation), or photons (electromagnetic radiation) – each of which would presumably have different effects.

Further, just like baking food, the intensity of the radiation and the time spent ‘cooking’ are also important (Ashbuugh, 1988); e.g. ultraviolet (UV), X-rays, and gamma-rays are all different wavelengths of electromagnetic radiation (photons), but gamma radiation is "harder" than UV, so should work more quickly, and perhaps cause some color-changes (for better or for worse) that don't happen with UV bombardment.

I checked the table's reference; the table in this wiki article appears be a verbatim copy of the table in that magazine article (Ashbuugh, 1988), with no further information about the type of radiation. In the text of his article, Ashbuugh (1988) seems to suggest that most radiation treatment is done via electromagnetic waves (photons), but I couldn't find a clear statement to that effect, and have doubts about my inference. (For example, I think that non-penetrating beta radiation would just produce secondary electromagnetic radiation when the electrons are stopped at the surface, so other than intensity is functionally the same as photon radiation. Maybe I'm wrong.) For his version of the table, Ashbuugh (1988) references a book, which I do not have easy access to: Nassau, K. (1984). Gemstone Enhancement. New York: Butterworths.. Anybody game for research?

Good point. I'll see if I can help. --BorgQueen (talk) 13:17, 21 October 2022 (UTC)[reply]

As of[edit]

Ermm, @Bearcat, what about the As-of template used in this article...? It's not generating a red-linked category even though it's talking about something existed in 1987. (See the Notes section.) BorgQueen (talk) 08:17, 11 April 2023 (UTC)[reply]
