Meet the Jewelers

Mineshaft Designs & Treasures is a jewelry business that marries the elegance of gold and precious stone pieces with the strength and practicality of sterling silver.  Mineshaft Designs was founded on the principles of honesty and respect for our clients. The goal of our shop is to bring our community high-quality, handmade jewelry at a reasonable price. Our hope is that we can sell our customers pieces they can enjoy for a lifetime. 

We specialize in custom mountings of certified authentic historical coins, one-of-a-kind jewelry, and repairs. Our jewelers utilize precious metals, precious and semi-precious stones in our creations. Our primary market consists of individuals and families that have an appreciation for carefully crafted art in the form of worn jewelry, that is never mass produced. We often connect with coin collectors and people who are fascinated with history. We have been happily serving the sunny, beautiful Florida Keys and beyond for over 10 years. We continuously adapt and incorporate new designs so that our pieces remain unique.

Very friendly and helpful service! Antonio is the man! Helped me find my first coin necklace with authenticated certification. This shop exceeded my expectations! Will be buying from them again!

Love this jeweler! Purchased my first Atocha charm almost 10 years ago and have been back every year and bought jewelry here every time! They make and sell quality pieces and stand behind their products! Have received many compliments on my Atocha, Key West and Hurricane jewelry.
