Beryl Beryl Beryl ( ) is a mineral composed of beryllium aluminium cyclosilicate with the chemical formula BeAlSiO. Well-known varieties of beryl include emerald and aquamarine. Naturally occurring, hexagonal crystals of beryl can be up to several meters in size, but terminated crystals are relatively rare. Pure beryl is colorless, but it is frequently tinted by impurities; possible colors are green, blue, yellow, red (the rarest), and white. Beryl is also an ore source of beryllium.

GemStone played an important sponsorship role in the Smalltalk Industry Council at the time when IBM was backing VisualAge Smalltalk, now owned by Instantiations, Inc. After a major transition, GemStone for Smalltalk continued as "GemStone/S" and various C++ and Java products for scalable, multitier architecture distributed computing systems evolved into the "GemStone/J" product. This in turn gave rise to "GemFire", an early example of a Data Fabric for complex event processing (CEP), event stream processing (ESP), data virtualization, and distributed caching.
