What Clients Say
The Question Everyone Asks
Compared with buying one of our ready-made rings, custom runs about $300 more. That covers the CAD renderings and your 3D model.
The stone and the metal cost what they cost either way. What changes is that the design is drawn around you, instead of chosen off a shelf.
How It Works
About an hour at 1544 South Street. We talk through what you're picturing, look at showroom settings and diamond samples, and you leave knowing what it costs and how long it takes. Bring the inspo board of rings you've been saving. Don't have one? No problem.
ComplimentaryAbout a week later, five to ten custom designs created from your vision with our design direction. You choose the direction from there. Most jewelers in the city charge $300 to $500 for this step.
Five to ten designsA 3D rendering, then a printed model you can hold and see at scale. Check the proportion and the presence of it before anything is cast. This is the last point at which anything can change.

In Their Words
Reuben is phenomenal!! We designed an engagement ring with him and he was patient, kind, and attentive to our interests. At no point did I feel he was pushing one option over another in his own interests.
Lincoln
Reuben custom designed my engagement ring and our wedding bands and they turned out exactly how we wanted! So unique and such a nice experience. His shop is beautiful, I end up buying something every time I’m in it.
Holly
My wife and I inherited heirloom wedding rings from our grandparents that we hoped to incorporate into our own, but didn't really know where to start. Ruben at Workshop Underground could not have been more helpful and great to work with.

Who Designs It
Ben Luna has spent nearly two decades designing jewelry. Before opening Workshop in 2015, he led the product design team at the Metropolitan Museum of Art, where he created thousands of designs.
Now it's one studio on South Street, and eight custom clients a month.
After the Ring
The proposal is usually a surprise, which means the ring has never been sized on the actual hand. So the first year covers that, and the rest covers everything after.
Full warranty on the ring and its workmanship.
One resizing in the first year, at no cost.
Bring it in whenever, for as long as you own it.
Annual prong and setting inspection, also for life.
Custom work is final sale. No returns.
