At Mark Shimizu Design in Downtown Windsor, we're embracing this trend with two beautiful sterling silver chains:

🤍 22" Groove-Textured Cable Link Chain – $233

💎✨ Continuing to learn, grow, and bring new ideas to Mark Shimizu Design!

Last week, Ty had the honor of representing our family-owned jewelry store at the Stuller Bridge Program in Lafayette, Louisiana!

The experience provided an incredible opportunity to connect with jewelry professionals from across the industry, exchange ideas, and learn more about the changing trends, markets, and opportunities shaping the future of jewelry.

From conversations about the evolving jewelry industry to exploring new approaches to customer service, custom jewelry, and showroom experiences, Ty returned to Windsor with plenty of inspiration and ideas we're excited to explore.

Why is continuing education important to us at Mark Shimizu Design?

Because we believe that providing exceptional jewelry services means never becoming complacent.

With decades of experience in the jewelry industry, our family has always taken pride in offering personalized service, quality craftsmanship, and expertise. But experience alone isn't enough. We also recognize the importance of staying informed, embracing new ideas, and adapting as our industry continues to evolve.

Whether you're visiting us for custom jewelry design, on-site jewelry repairs, heirloom restorations, engagement rings, or simply browsing our selection of fine, estate, or fashion jewelry, our goal is to provide an experience that combines traditional craftsmanship with modern knowledge and innovation.

We're grateful for opportunities like the Stuller Bridge Program that allow us to invest in our team's professional development and bring that knowledge back to the community we serve.

Thank you to Stuller for the opportunity to learn, connect, and grow! ❤️

And to our customers throughout Sonoma, Marin, Mendocino, and Napa County, thank you for continuing to support our family-owned business. We look forward to sharing some of these new ideas with you!

🎉🎂 Happy Birthday to the man behind Mark Shimizu Design!

Today we’re celebrating Mark Shimizu, one of the owners of Mark Shimizu Design and the custom jeweler behind so much of what we do at our family-owned jewelry store in Windsor, California. 💎

For decades, Mark has dedicated himself to the art of fine jewelry. On any given day, you might find him at his bench designing and handcrafting a custom piece, setting gemstones, restoring a treasured heirloom, or completing an intricate jewelry repair.

His craftsmanship is at the heart of Mark Shimizu Design, but those of us who get to work alongside him know just how much of himself he puts into every piece and every customer who trusts us with their jewelry.

So today, instead of showing off one of Mark’s latest creations, we’re celebrating the guy who creates them. ❤️

🎂 Happy Birthday, Mark! Here’s to another year of family, creativity, craftsmanship, and plenty more time at the jeweler’s bench.

If Mark has designed, made, repaired, or restored something special for you over the years, we’d love to hear about it in the comments—and be sure to wish him a Happy Birthday! 🥳
