Welcome to 307 Gem Company
Where Every Gem Has a Story
Thank you for visiting 307 Gem Company. I’m truly honored you’re here.
What started as a fascination with gemstones, antique jewelry, and hidden treasures has grown into something much more—a family business built on passion, honesty, and the excitement of finding pieces that deserve to be cherished for generations to come.
Every gemstone, vintage treasure, and strand of beads in my collection has been personally selected because it stood out to me in some way. Whether it’s the brilliance of a natural stone, the craftsmanship of an antique piece, or the uniqueness of a vintage find, I believe every item has a story waiting to continue with its next owner.
Based in Casper, Wyoming, 307 Gem Company is proudly family-owned and operated. While I focus on sourcing exceptional gemstones and jewelry, Patrick works behind the scenes to create a secure, reliable, and enjoyable shopping experience. Together, we’re committed to building a business that values quality, integrity, and genuine relationships over simply making a sale.
Outside of the business, I’m a proud mom to three amazing children, and our family is the heart behind everything we do. Their love and encouragement inspire me to build something lasting—one beautiful gemstone at a time.
What You Can Expect
A Personal Shopping Experience
Thoughtfully Curated Collections: Every gemstone, antique jewelry piece, and vintage treasure is hand-selected with care and purpose.
Honest & Transparent: I believe in accurate descriptions, quality photography, and straightforward communication so you can shop with confidence.
Family-Owned Values: Every order is prepared with the same care and attention I’d give if I were sending it to a friend.
A Love for Learning: As I continue studying gemology and antique jewelry, my goal is to share that knowledge with you so you can buy with confidence and appreciation for every piece.
Whether you’re searching for your next collection piece, creating handcrafted jewelry, or looking for a meaningful gift, I hope you find something here that speaks to you.
Welcome to the 307 Gem Company family. I’m so glad you’re here.
