Welcome to Hyperion Sherlock, Lotus Gemology's Advanced Gem Inclusion Search Engine. This allows you to search for inclusions by the gem species (corundum, spinel, beryl, chrysoberyl) or variety (ruby, sapphire, emerald, alexandrite). You can even search by country of origin or locality. The result will be a table listing all known solid inclusions in that gem material. Each inclusion is fully documented with references of when it was first discovered.

Where we have photographs of that inclusion, those will also show up in the search. See anything missing? Let us know with the reference and we will consider adding it to the database.

Hyperion Sherlock is part of Lotus Gemology's ongoing effort to provide tools to help gemologists learn more about gems. Enjoy!
