Copper Nuggets from Michigan
Michigan's Keweenaw Peninsula is the most important locality in the world for pure native copper. Mining began in 1845 and continued until 1982 and over 7 million tons of refined copper were recovered from Michigan's copper mines. In the early 1900s, it led the world in copper production and "Lake Copper" was the purity standard to which other refined copper was compared. Long before the mining operations of the past century began in the Keweenaw, pre-historic peoples mined copper from the mineral rich veins.
Price is for one copper Nugget intuitively picked.
each piece measures ≈ 1.75” to 2” and weighs ≈ 35 to 40 grams
Copper nuggets may vary in size, color and shape as they are an organic material.

*You will want to order at least 1/2" larger than the exact size your wrist or ankle measures.
• When ordering a necklace for your child, keep in mind that you want to necklace to be loose around the neck but NOT long enough to reach over their chin and into their mouth (to prevent them from biting the beads).

Let customers speak for us
All of my babies have worn amber necklaces. I found Baltic Mermaid with my 5th and I won’t go back. They are SO cute. I just sized my guy up from and the woodsman necklace. The little moon charm on Moonbeam is the sweetest thing ever.
I love all my crystals. They are so beautiful and my collection is slowly growing while I learn more about them. I’ve learned a lot from Baltic Mermaid’s Instagram and online sales when Jessica explains about each crystals benefits. Fun new hobby for me!
Beautiful necklace. Great quality and fast shipping with amazing customer service as usual!
This is an absolutely gorgeous necklace!!! The gemstone's meaning really suits me.
It was my first time ordering from the shop, and I will be a returning customer! These are my favorite two pieces- I'm OBSESSED with the pink opal palm stone! It's stunning. Also loved the customer service and the eco-friendly packaging was super cute.
I like this bracelet, it's beautiful! The bracelet fits perfectly. Fast shipping also.
Crystals we prettier in person and the shipment was faster than expected. The cute sticker was so awesome bonus
Will always shop with Jessica for my crystals
My crystal flower bouquets are a breathtaking adornment for my antique piano—like a whisper of elegance from a bygone era. Thank you!
Ocean jasper has become a new favorite and this does not disappoint. It has such a fascinating pattern that I can't stop oogling it! Love it!
A new favorite of mine is amazonite and these little but impressive spheres are sweet! Love them
The sweet gifts and treasures I have collected bring so much joy. I can't decide what is my favorite but I absolutely love the ocean jasper! Another thing I love about Baltic Mermaid is the shipping..so fast and so mindful without excess plastic fillers! Love this shop! Thank you for sharing the joys of the planet with us!
I have purchased several Phosphosiderite palms from Baltic mermaid and each one is so vivid in color with the most beautiful variations in swirls and patterns!
I bought this necklace because it reminded me of the Navajo bolos and jewelry that my father and grandfather used to wear. While this is not Kingsman turquoise, it is absolutely stunning. I can’t wait to wear it out :)
I love this Rainbow Moon bracelet so much! It stands out and I always receive compliments on it. Wonderful shop, I love to buy from Baltic Mermaid!
Very pleased with my clear crystal quartz. It’s a beautiful addition to my collection!
