New Hampshire is certainly not lacking for gemstones to find.

Beryl is a gemstone commonly found in the abundant granite rocks in New Hampshire. Beryl refers to a family of minerals that includes emerald (green), aquamarine (aquamarine blue), morganite (pink), heliodore (yellow-green), golden beryl (yellow) and goshenite (colorless).

New Hampshire’s iconic ‘Old Man of the Mountain’ was composed of Jurassic Conway granite.

The best places to rockhound in New Hampshire are along hillsides and mountain ridges where pegmatite minerals are exposed. The Moat Mountain site is popular with collectors for finding Smoky Quartz on Feldspar, as are old quarries and mines. Gold panning in streams and rivers can be particularly fruitful in the northern part of the state.
