Buy, sell & redesign with us...Give your old jewelry new life.
We know every piece you acquired was once special, but every so often they lose their luster over time. What you loved a decade ago may not fit your lifestyle now. Know when to sell or redesign and make those decisions with confidence, using up to the minute market information from our team of world-wide professionals.
We have years of experience serving our clientele remotely. From buying an engagement ring to building a major collection, or perhaps even making those gifts from your "ex" disappear, we can help!
Each project is handled with care and discretion.


“Donna and her team are amazing.  In the new normal of a remote world, the logistics of purchasing a statement piece of jewelry from Donna were flawless.  Donna has a great, secure process that provides me with the confidence to make a significant purchase. I look forward to a future purchase with her.”

"Donna is a gifted designer and has impeccable taste. Whether creating a custom piece or finding that special gift, her attention to detail and client service is exceptional. We are so pleased our son is working with Donna for his first big purchase!

“What a pleasure to work with such a true professional. Donna was amazing, walking me through every detail that related to my custom piece. I was worried my budget wasn’t big enough to warrant contacting such a high-end firm, but boy I’m glad I did! The personal attention and value for money was unbeatable.”

Minneapolis, MN

The diamond ring Donna created for me is so gorgeous... I'm still floored.  She and Alex are simply the BEST!  Donna, I can't wait to work with you both for the rest of my life!"
