What kind of ring workshop is Robenta Seongsu?

Robenta Seongsu, which helps you make happy memories along with your ring, runs on the motto "If you're going to make it once, make it properly with a good product." Prices are a bit higher than nearby shops, but they say the ring quality, the silver and the premium packaging mean you can make a ring that's perfectly good for an anniversary date or a gift.

  • They have professional ring-making equipment, so they say the shine and quality of the rings are much better than at ordinary workshops
  • Staff who have completed friendly-service training explain everything carefully
  • It's a great indoor date course in Seoul where you can make a ring yourself

Robenta Seongsu highlights at a glance

  • It's within a 5-minute walk of Seongsu Station Exit 3, so it's easy to get to
  • Classes are held in a clean, pleasant shop with European-style interiors
  • They only use products designed and inspected by a jewelry designer with 30 years of experience, so the designs are varied and the quality is high, they say
  • There's a separate design lab, and designs are updated regularly, so you can make a unique ring of your own
  • They only use moissanite, a diamond substitute, not cubic zirconia, so it sparkles much more, they say
  • Same-day completion is the rule: 1 hour of making, 1 hour of finishing in the shop, and it's done

🙌🏻 The silver used for ring making is 92.5% silver, and they say it isn't the kind supplied to the general market but top-grade silver filtered through inspection after inspection, the most harmless to the body.

How to get to Robenta Seongsu from Seongsu Station

Seongsu street on the way from Seongsu Station to Robenta Seongsu

After lunch I wandered the streets of Seongsu, and before I knew it our reservation time at Robenta was coming up, dun dun!! Walking briskly, and there it is, the ring workshop Robenta Seongsu.

Robenta Seongsu is on the side close to Seongsu Station, so I think you could make it your first stop and then enjoy the rest of Seongsu~

Stairs up to the 3rd floor of the building housing Robenta Seongsu

Robenta Seongsu is on the 3rd floor, so up we go~ The building has no elevator, but the stairs are low, so it's easy to climb.

When you reach the 3rd floor, the mood seems to change a little! Oh, I see it, the entrance to Robenta! Okay, let's go in and make rings~

Inside the Robenta Seongsu workshop

The inside of Robenta is clean and pleasant, decorated in a European style. There are information signs here and there for convenience,

and further in, desks for making rings are lined up side by side, which gets you excited.

How does the Robenta Seongsu ring-making class work?

1. Choosing a ring design

The class at Robenta Seongsu starts with sitting down, listening to the staff explain, and trying rings on to choose a design. Once I was ready and seated, the staff member explained everything carefully and kindly.

Maybe because they only use products designed and inspected by a jewelry designer with 30 years of experience, the ring designs are varied and the quality is very, very high~

After the explanation, it's time to try rings on and pick the design you like~ Every design was so pretty that choosing was really hard, but there was one that suited my clumsy hands, so I picked quickly.

2. Checking your ring size

Once you've chosen a design, it's size-check time, dun dun!!

Bundle of sizing rings for checking ring size

You try on a jingly, key-like bundle of sizing rings to check your size. I worried that trying on all sorts of rings might throw off the measurement, but the staff member checked so carefully that I felt reassured.

Once you've decided on plating and initial engraving, the real ring making begins, dun dun!!

3. Making the silver ring

We moved to our seats and put on the aprons that were in the desks.

I like this. I look kind of like a pro -0- I'm drunk on how cool I am, here to make a ring, hahaha

Time to focus on class for the sake of a gorgeous ring. I was pretty nervous, but the staff member at Robenta Seongsu explained everything so kindly and thoroughly that I had a really fun time, yahoo~

Ring-making equipment at Robenta Seongsu

And I like that the equipment looks kind of impressive. Newni, drunk on herself as she carefully makes her own ring just as explained: don't I look pretty cool like this?

Silver ring in progress with design lines marked

The design lines were marked separately, and they explained in detail how the ring should be made, which felt reassuring.

They also told me the name, purpose and use of each tool in real detail, but amazingly, after making the ring I remember none of it. I must have been so focused -0-

Newni's nimble hands worked hard on a ring too, haha

When is your Robenta Seongsu ring ready, and what to do in Seongsu while you wait?

At Robenta Seongsu, after you finish the roughly 1-hour hands-on class, the workshop handles the professional steps, and you can pick up the finished ring about 1 hour later. If you're planning a Seongsu date, I think a course where you make rings for 1 hour, eat and stroll, then come back for them 1 hour later would be just right.

Here are the rings of Ahn Gwiyeomdungil and Newni, who actually made rings, had snacks, drank coffee, strolled and came back for them. Dun dun!!!! Nonghyup Bank~ Ah-rwa? (Korean wordplay joke.) So pretty~

The shopping bag at Robenta Seongsu is classy too. It would be really great for an anniversary or a gift.

And that's the end of our fun time at Robenta Seongsu.
