Search For Michigan Gemstones

I wanted to share my search for Michigan gemstones with all of you.  My goal was to search for Leland Blue Stones, Petoskey Stones and beach glass.


Lake Michigan in the Spring is beautiful!  The beaches are so fresh and clean from all the Winter storms.  Many Lake ‘icebergs’ were still hanging around.

Zebra mussel shells had collected in mass at certain areas along the water’s edge. Unfortunately, these are not native to the Lake and are quite destructive to the Lake’s natural ecosystem.

Our first day on the beach lasted approximately three minutes!  The wind was gusting at 30 mph.  It didn’t matter that we had thermal underwear, parkas, scarfs, mittens, etc.!  It cut right through us!  My husband beat me back to the car and took this ‘lovely’ pic of me!



Two days later we were able to walk the beach and search for nature’s treasures.  I found some beautiful fossils but not what I was searching for.  Was I disappointed?  Absolutely not!  Viewing Lake Michigan’s beauty was prize enough!  I now have an excuse to vacation on Lake Michigan again!

Identifying Petoskey Stones From Other Fossil Corals

I thought I would stop the confusion about identifying Petoskey Stones from other Fossil Corals.  If can be quite confusing, especially if you do not know what the identifying differences are.  I personally love these gifts from nature!  They make unique and beautiful custom jewelry.

First off, Petoskey Stones are found on the northern shores of Michigan.  They are fragments of the Devonian Period coral reefs.  Petoskey Stones are fossilized coral (flower animals) that lived 350 million years ago.

The most unique feature of the Petoskey Stone is that they have a light or dark ‘eye’ in each cell of the coral.  These ‘eyes’ can be either small or large.  Other corals do not have these ‘eyes’.  Colors vary from light tan or gray to darker hues of brown.  Due to the fact that Petoskey Stones actually started out red in color, you might be able to find a stone with some red in it!

United States Is Gemstone Rich

Did you know that the United States is gemstone rich?  Every state has its own special assortment of nature’s treasures.  Take North Carolina, for example.  Emerald Hollow Mine allows the public to mine for emeralds.  Love opals?  Head to Nevada.  Bonanza Opal Mine and Royal Peacock Mine let you dig your own.  Globe, Arizona has one of my favorites, Sleeping Beauty Turquoise.  The mine is found in a mountain range that resembles a sleeping woman!
