This handcrafted Silver Signet Ring features a 3mm synthetic black diamond set into a rugged, matte-finished top plate. Cast in solid sterling silver with the lost-wax method, it has a satisfying weight, raw texture, and gently oxidized edges for extra depth. The interior is polished smooth for easy, everyday wear.

The synthetic black diamond offers the bold, dark look of a natural stone with better consistency, durability, and ethical sourcing — a clean, responsible choice for modern jewelry lovers.

Designed for both men and women, this ring works as a modern wedding band, a meaningful gift, or a standout pinky ring. Each piece is made by hand in my Tychy, Poland workshop, giving every ring unique texture and character. Raw, expressive, and unmistakably crafted with intention.

A very nice & special ring, highly comfortable, like it a lot! Top customer service, very friendly and supportive, quick answers to questions, fast delivery! It was easily possible to customize the ring so that it matched my preferences (got is with a custom orange stone). It's my 2nd ring from this shop, and will be for sure not the last one 😉 Thanks a lot, Mateusz, for this beautiful piece of art!

F.A.Q.

They appreciate cut and details, things that aren't so obvious.

What materials do we use for your rings and pendants?

At Spirit Workshop, we’re passionate about giving back to our planet! We proudly use recycled materials whenever we can. For our stunning wooden pieces, we collect used skateboards from our friendly skate shops (and yes, you can exchange your old decks with us!) and we also use leftover wood from local veneer factories, giving materials a new lease on life! Our sterling silver is also recycled; we source old jewelry locally, refine it to achieve 99.9% pure silver, and blend it with a high-quality Italian alloy. This results in durable, beautiful pieces that are perfect for daily wear—this mixture creates the beloved 925 sterling silver that you know and love.


As for our zirconium pieces, we obtain this rare and remarkable metal from one of the largest suppliers in the world.

Do you offer customization for your rings?

Heck yes! We love bringing your ideas to life! You can choose to engrave inside and outside of our metal rings or even add an 8-letter engraving on wooden rings. Just keep in mind that customization comes with an extra cost, so please contact us before placing your order to discuss details. And remember, customized pieces can’t be returned or exchanged, but we’ll be there for you if resizing is needed!

Do you offer custom pieces, and how does that work?

Oh yes, we absolutely love creating custom pieces! Whether it’s an engraving or a completely unique design, feel free to contact us with your ideas, and let’s bring your vision to life together! Keep in mind that custom creations take a bit more time and come with additional costs (starting at €70 for wooden pieces, €100 for zirconium, and €250 for sterling silver), but we’ll ensure every detail is just right. Let’s work together to create something truly special!

No worries at all! It happens to the best of us. If you find yourself in this situation, please reach out to us right away! We’ll guide you through the exchange process to ensure you get the fit just right. Your comfort is our priority!

How should I get sized for a ring?

Great question! We recommend visiting your local jeweler to get your accurate ring size measured. There are plenty of online guides out there, but nothing beats a professional sizing. If you have your size but aren’t sure what to choose from our options, just contact us! We’re here to help you convert that size with ease.

Are the pieces really made by you?

YES, YES, and YEEEES! We take immense pride in creating each piece by hand. This is the very essence of our shop—the spirit of crafting beautiful, unique items with love and care. We believe in slow fashion and pour our hearts into every ring, avoiding the rat race to make something special for you!

Do you offer try outs for your products?

We totally get the curiosity! However, we don’t offer try outs as each piece is made to order specifically for your size. This means we craft our items with love and care to ensure they fit you perfectly! If you have any sizing questions, don’t hesitate to reach out – we’re here to help!

Can I cancel my order after purchasing?

Absolutely! You can cancel your order within 48 hours of purchase. After that, we start working on your ring, and cancellations won’t be possible. If you need to make any changes, just shoot us a message within that time frame, and we’ll be happy to assist!

Do you accept exchanges?

Absolutely! We’re more than happy to help you with exchanges. If you have any sizing issues or concerns, reach out to us directly! We’ll guide you through the process to ensure you get the perfect fit. Just a friendly reminder—please hold off on sending back any pieces before you consult us, as we want to make sure everything goes smoothly for you!

What is the return policy?

We understand that you want to be completely satisfied with your custom ring! Since each piece is made to order, we can only accept returns if there’s an error on our part. For example, if you ordered a size 10 and received a size 11, just let us know! As long as you can provide proof of the mistake, we’ll gladly accept the return. Your satisfaction is our priority!

What should I do if my item is damaged during shipping?

Oh no! If your piece arrives damaged or if it seems to be lost in transit, please contact us right away. We’re here to help you navigate through this situation, and we won’t leave you hanging. Just let us know what happened, and we’ll make sure to find a solution for you!

Do you still skate?

Absolutely! Skateboarding is still a huge part of our lives and the reason we started Spirit Workshop. We’re grateful for the journey that brought us here, and while we’re devoted to crafting beautiful jewelry for you, we always make time to hit the skate park, too!

Why does it take longer to produce sterling silver rings compared to other types?

Ah, the wonderful world of silver crafting! The production of sterling silver rings is quite intricate. First, we create a wax model, which is then cast and meticulously crafted into the beautiful finished piece you’ll love. This process ensures that every ring meets our high standards of quality and comfort. It may take a bit longer, but good things come to those who wait, right?
