Lumps.
These are lovely solid lumps of beryllium metal, probably produced by dropping molten Be into water. They are free of dust and very hard which is good from a safety point of view as any powder which might be breathed in must be strictly avoided. They feel incredibly light and make a nice clinking noise when hit together.

High voltage insulator.
Beryllium oxide, also known as beryllia, has a very high melting point and is an excellent electrical insulator, Surprisingly though it is very good conductor of heat, almost on a par with some metals. These are useful properties which in this case are deployed in a high voltage electrical insulator. There is a label on the device warning that it should not be machined or broken due to the potential toxicity of the dust..

Beryl.
Beryl, a beryllium aluminium silicate, is a common mineral but its gem varieties are highly prized. Emerald is the green variety of beryl, colored by impurities of chromium and vanadium. Today most noted emeralds originate in Colombia but ancient emeralds all came from mines south of El Kassir in Nubia, which were worked from approximately 3000BC. Cleopatra was reputed to have had a Nubian emerald engraved with her own portrait. This specimen is from the Russian Urals.

Emerald.
This emerald specimen hails from the type locality, Muso, Boyaca, Colombia and displays the clarity and rich green color for which Colombian emeralds are so prized. The Colombian emerald mines were worked by native peoples long before they were taken over by the Spanish in 1537. Other gem varieties of beryl include aquamarine (blue-green), bixbite (a red beryl found exclusively in the Wah Wah Mountains in Utah), goshenite (clear), heliodor (yellow) and morganite (a pink variety named after J. P. Morgan).
