Thin ENGAGE wedding bands at a Seongsu ring workshop: Robenta Seongsu

In short

Robenta Seongsu is a ring-making workshop a 5-minute walk from Exit 3 of Seongsu Station in Seoul. From 24 designs, the couple chose the slim ENGAGE band and made two rings at 95,000 won each, with careful 0.5-unit ring sizing and a size-check step along the way. Made in 92.5% silver with moissanite, Robenta Seongsu is an unusual date idea that turns out a ring solid enough to wear as a wedding band.

Getting the lettering engraving is free with a Naver review, so I'd definitely recommend doing it@@

Ring designs

There are 24 designs and they're all so pretty that I had a hard time deciding. It was great that you could try them all on without any pressure!!

Trying them on is different from just seeing photos, but it still helps to pick a few favorites in advance and check them out!!

Application form for model name, size, and engraving details

We started by filling out the model name, size, and engraving details on this form!

Why we chose the ENGAGE band over LOVENTA

Seeing it in person, the double-line design looked prettier than I expected. I'd basically already decided on LOVENTA after falling for it in photos, but trying it on felt totally different! We prefer thin rings, so we went with ENGAGE!!

Ring sizing in 0.5 units and the 4 plating colors

Another thing I loved about Robenta was that you can choose your ring size in 0.5-unit increments!! Being able to go with 9.5 or 10.5 took a lot of the guesswork out.

Comparison of plated and unplated ring samples

There are 4 plating colors, and the photo on the right compares an unplated thin ring with a plated thick ring! The difference from plating doesn't seem to be that big.

Once you pick your ring design and size, there's a step where they carefully check the fit, so the experience never feels like a waste of money@@

Checking the ring size fit
Filing the ring by hand

You'd think you'd be worried about messing it up while making it, but there's nothing to worry about at all because the staff explain everything so kindly!! They kept complimenting us, which boosted my confidence.

Using various files to smooth the ring

They demonstrate each step with the different files before you do it yourself, so there's no chance of getting confused!!

With so much specialized jewelry-crafting equipment, the ring's shine and quality can't help but be good. It goes from smooth and smoother to a glossy finish.

There are various designs displayed out front, so there's fun in just browsing.

They said the reason Robenta's rings feel so high-end is that they only use products designed and inspected by a jewelry designer with 30 years of experience.

White and green ring boxes and packaging bags

The finished ENGAGE rings and their packaging

You can choose your packaging bag and ring box in either white or green! We got our handmade rings back an hour later! Watching and helping each other through the making process made us feel even more attached, so they looked prettier too. Gotta wear these Robenta rings for our pre-wedding photoshoot.

The packaging bag is fancy, and the ring box is pretty and sturdy, so it seems great for keeping them stored!! They use moissanite, a diamond substitute rather than cubic zirconia, so it sparkles so much more and really feels like a platinum ring!!

There's even a phone stand for filming the ring-making process like this! A place to stack up tons of memories = Robenta.

The finishing wait and picking the rings up

After about an hour of making the rings, they finish them up for you, and that took less than an hour! There's so much to see in Seongsu that even an hour felt short. It was also nice that you just need to arrive before closing time. So flexible.

The Robenta building has a back entrance too, so make sure to find the front entrance when you visit!

Verdict: does the ENGAGE band work as a wedding ring?

Making the ring itself was fun, but even more than that, the process of happily debating which ring to get with the friend or partner making it with you, and having those conversations, felt like a really strong way to build memories!

I liked it even more because they said they only use the highest grade 92.5% silver, filtered rather than the silver typically sold on the market, so it's harmless to the body!! Since it's such good silver, the quality is clearly a cut above, making it perfectly suited as a wedding ring too!!

It's on the pricier side compared to what you'd normally expect from a ring workshop, but that's exactly why it's high-end enough to keep for a long, long time, making it a great pick for an anniversary or an unusual date idea!! This place is Sombrero Galaxy-level good!!🌌
