Origin of Gemstones in Igneous, Sedimentary, and Metamorphic Rocks

Date:

Speaker: Prof. Steve Okulewicz (Hofstra University, P.G., C.P.G.)

Location: Monmouth Worship Center 37 Vanderburg Rd., Marlboro, NJ 07746

Where do gemstones come from—and what types of rocks do they form in? While many people assume gemstones originate from a single geological environment, the reality is far more complex. Gemstones can form in igneous, sedimentary, and metamorphic rocks, each requiring specific conditions of temperature, pressure, and chemical composition.

In this engaging presentation, Prof. Steve Okulewicz explores how some of the world’s most sought-after gemstones—diamonds, rubies, sapphires, and emeralds—are created. Learn how these gems form deep within the Earth, the geological processes that bring them closer to the surface, and why some gemstones can originate in multiple environments.

The talk will also highlight where these gemstones are found around the world, offering insight into the global distribution of gem deposits and the science behind their formation.

Perfect for collectors, hobbyists, and anyone interested in geology, this presentation provides a fascinating look into the natural processes that create Earth’s most beautiful treasures.
