Today I saw an article about it in National Jeweler that had another awesome photo of inclusions,
Lotus Gemology has made its inclusion photomicrographs available for the trade to see through its new, free database, Hyperion. This photo shows melted crystals surrounded by “runny channels” in a heat-treated Thai/Cambodian natural ruby. (Image courtesy Lotus Gemology/Photo credit: E. Billie Hughes)
At the end of the article they said Lotus has now released another free database of trade related references, Four Treasures:
Concurrent with the launch of Hyperion, Lotus also has debuted Four Treasures, a free database containing more than 5,000 references intended to help with research relating to gems and gemology.
Built from the lab’s internal reference database it uses for research—from thousands of hours of work over nearly four decades—Four Treasures provides a search for books and papers about gemology from a variety of sources. It is particularly strong in citations relating to ruby, sapphire, spinel and jade.
“It is our way of giving back to those who have come before us, and going forward, providing tools to researchers who are working to push gemology ahead,” the lab said on its website.

Here is the direct link to Four Treasures. They say if you know of a reference that's not on the database, to contact them and they will consider including it. Much thanks to the Hughes' for all their work and dedication to the industry.
