Class Details
This section offers essential details about our classes, including duration, materials provided, and common inquiries.
Absolutely! At KOBO, we strive to bring the artistry of fine jewellery crafting to everyone, whether it’s working with precious metals like 18K Gold, Platinum, or Silver.
Our goal is to ensure that every customer leaves our workshop with a memorable piece, crafted with care and creativity during our 2 to 3-hour sessions.
Children under 12 must be accompanied by an adult. Please contact us in advance if you wish to bring children so we can make appropriate arrangements.
No. Due to limited space and safety concerns, only attendees making the jewellery may stay in the workshop area.
Non-participating guests may be requested to leave or explore nearby areas.
Our studio is located on the 3rd floor and is accessible via stairs only. Please contact us ahead of time so we can assist you if needed.
Explore our diverse range of classes, spanning from bridal and 18K/platinum to silver jewellery crafting.
Delve into our extensive menu, which includes ring-making sessions, as well as classes for crafting bangles, necklaces, and earrings. To learn more, please visit our workshop menu here.
Silver classes typically run for 2 hours, while bridal (K18/Platinum) classes require 3 hours for completion.
🔸 Bridal (K18/Platinum) Classes
2 time slots are available daily: 10 am–1 pm or 2 pm–5 pm
🔸 Silver / Selected K18 Gold Classes
3 time slots are available daily: 10 am–12 pm, 2 pm–4 pm, and 5 pm–7 pm
🔸 Group Classes (4–6 pax):
2 time slots are available daily: 10 am–1 pm or 2 pm–5 pm
Depending on the jewellery designs, group sessions typically run for 2.5 to 3 hours. Please note that the workshop process may be adjusted for group sessions. We recommend planning your designs and engravings in advance to make the most of your hands-on experience.
Note: There will be short breaks during the workshop for our team to refine your rings and prepare them for collection.
In our studio, we specialize in working with a variety of precious metals, including:
🔸18K — Champagne, Rose, and Yellow Gold
🔸Platinum
🔸925 Silver
For silver/18K classes that do not require stone settings, you will be able to collect the piece after the workshop.
🔸Wedding Rings:
The workshop provides a comprehensive experience — the opportunity to engage in hand engraving and hammering textures on the metal ingot, which will then be transformed into your rings. If you’re crafting with 18K Gold, you’ll be able to collect your rings at the end of the class.
However, please understand that stone setting requires a lead time of 6 to 8 weeks. This is because the rings will need to be sent back to our Japan atelier for the final finishing touches.
🔸Engagement Ring:
The workshop focuses on crafting the ring base, allowing you to enjoy hand engraving and creating textures on the metal ingot, which will be transformed into your ring.
Following this, our craftsmen from Japan will design a crown to fit the specific stone chosen, along with the stone-setting process, with a lead time of 6 to 8 weeks before completion.
We recommend wearing comfortable clothes. All tools and materials will be provided, so there’s no need to bring anything.
Absolutely! Many of our participants attend solo. Our instructors provide hands-on guidance to ensure a fulfilling experience for everyone.
Our workshops maintain a 1:1 instructor-to-group ratio. Should you choose to craft two rings independently, rest assured that our instructor will facilitate your progress, ensuring completion within the allocated session.

Please note that visits are strictly by appointment only, as we do not accommodate walk-ins.

Jewellery Care, Resize & Warranty
This section outlines essential information on caring for your jewellery, resizing options, and the warranty coverage for KOBO pieces.
By following proper care tips, you can help preserve the beauty and longevity of your K18 Gold, Platinum, and Silver pieces for years to come.
Check out our Jewellery Care Guide to learn more about your jewellery care tips and maintenance.
To restore shine to your silver pieces, you can try the following methods:
- Polishing Cloth: Use a soft, non-abrasive polishing cloth specifically designed for gold or silver jewellery. Gently rub the cloth over the surface of the silver to remove tarnish and restore shine. The studio offers these for $5 each. If interested, please inform our instructors at the conclusion of the class!
- Baking Soda Paste: Make a paste by mixing baking soda with water until it forms a thick consistency. Apply the paste to the tarnished areas using a soft cloth or sponge, then gently rub in a circular motion. Rinse with water and dry thoroughly.
All KOBO jewellery includes a 1-year warranty from the date of collection, covering craftsmanship and material defects under proper usage. The warranty includes:
- 1 complimentary resizing (within ±2 size, subject to jewellery’s design)
