Today I'm sharing my visit to Robenta Seongsu, a ring workshop that turned out to be a perfect indoor date 💍

Visiting the Robenta Seongsu ring workshop in Seongsu

Why we made friendship rings in Seongsu after 9 years of friendship

At Robenta Seongsu, I made friendship rings with my Japanese friend, who I've known for 9 years 🤍 We'd planned to spend the whole day on a date around Seongsu, and I kept wondering what we could do to make a special memory. We finally settled on making rings, and it was honestly such a good choice, haha.

I'd made couple rings with my boyfriend before, but never with a friend, so it felt totally different. I was half excited, half nervous even before we went, haha. It felt extra meaningful, so my heart was pounding!

Where is Robenta Seongsu, and what is the workshop like?

Robenta Seongsu is about a 3-minute walk from Seongsu Station, so it's super easy to reach. You walk through those charming Seongsu-dong alleys on the way, which puts you in a good mood right at the start of the date, haha 😆

It's on the 3rd floor and easy to spot once you go up. The first thing I noticed when I walked in was that it's much bigger and more pleasant than I expected! There are lots of seats, so even a group would have no problem.

There's a coat rack by the entrance, and you just put your bag in the basket beside your seat and you're set 🙌🏻 I love details like this, haha.

How we chose the Axis ring design at Robenta Seongsu

I chose Robenta Seongsu because the workshop was set up by a jewelry designer with 30 years of experience, and the details really do feel a cut above 🤭 Even choosing the design is pure joy… there are so many samples that the time just flies, haha.

They range from daily rings to couple rings to wedding-ring styles, so you can pick whatever suits your taste 😚

Choosing a ring design at Robenta Seongsu

After a lot of dithering, I ended up choosing the 'Axis' design, haha.

Axis is unique and vintage-feeling but also elegant, so it was totally my taste…🫣✨ My friend hesitated too, and in the end we matched with the same design, haha.

Checking ring size

Once the design is chosen, they check your ring size, and mine is a 9, haha.

Is ring making hard for beginners?

At Robenta Seongsu you put on an apron and gloves and then start making the ring properly. The moment I had the apron and gloves on, I was suddenly in master-craftsman mode, haha.

The staff explained every step and demonstrated it themselves, so it wasn't difficult. Thanks to that, my friend and I could chat and take it easy while we worked, haha.

Every seat also has a phone stand, so it was great for filming a timelapse 📱 Perfect for making memories!

You get so focused that time really flies, aw. It was pure healing time…✨

The most fun part: polishing with the foot-pedal drill

The most fun part was grinding and polishing with the drill, haha. It spins when you press a foot pedal, which was so cool that I wanted to keep going…😆

What I really remember is how kind the staff were, aw. They kept looking after us throughout the session, and the atmosphere was relaxed, haha.

Free engraving with the Naver review event

At Robenta Seongsu, if you take part in a Naver review, they engrave your ring for free (worth ₩10,000), and you absolutely have to do this, haha. Adding the engraving doubles the meaning…🥹

Final stage of the ring class at Robenta Seongsu

How long does ring making take, and can you pick up the same day?

The class at Robenta Seongsu takes about 1 hour, and the finishing work takes another 1.5 hours or so. So we ate nearby and then went back to collect the rings 🙌🏻 They also contact you when the rings are done, which was convenient, haha.

I loved that it's finished the same day, so you can take it home right away. Finally, the finished rings…✨💍

I thought it sparkled while we were making it, but the finished ring is even crazier, haha 🥹 We went with a glossy finish and I love it so much!!

What comes in the Robenta Seongsu ring package?

With the Robenta Seongsu package you can choose white or green, and I picked white 🤍 The package looks so luxurious that I was surprised. It would make a touching gift, and I think anyone receiving it would love it, aw.

They also give you a care guide and a polishing cloth, plus a printed photo taken during the session, so it felt like they'd covered the memories perfectly too, haha.
