Sirius | The Brightest Jewellery Star
We founded our own jewellery brand, Sirius Jewellery, under which we create unique original designs — sometimes independently, and other times in close collaboration with our clients. This gives everyone the opportunity to become part of an exclusive private brand whose exceptional pieces find their way to people all around the world.
In this section, we introduce one selected custom project every month — from original jewellery designs and handcrafted rings to exceptional pieces featuring lab-grown diamonds.
Project of the Janury | Antares
Antares is a special project for one of our clients who wanted a ring featuring numerous diamonds while remaining perfect for daily wear. I was given complete creative freedom, which I always appreciate, as it reflects the trust of the client—but with that trust comes a great responsibility. Our goal was to deliver a ring that exceeded the client’s imagination.
From my perspective, the 1.50 ct central stone was the perfect choice, giving the ring a mesmerizing beauty and luxurious presence. We also added an exquisitely designed wedding band that fits seamlessly, enhancing the overall elegance and richness of the set.
I am incredibly proud to have received such positive feedback from the client on the final result. It is for this reason that the Antares ring has now joined the Sirius collection.
Welcome to the collection!
Best regards,
Michal

Project of the December | Polaris
This project is a personal one. I’ve always wanted rings like these in our collection. We already have a similar design, but this version is smaller, sexier, and more elegant—and it instantly became special to me.
It’s the kind of piece you can’t help but look back at, just like a car you truly love. We have many beautiful rings, but this one feels different. I’ve named it POLARIS, inspired by the bright guiding star—small, elegant, and captivating.
I apologize for sharing my own excitement instead of focusing on yours this time. I promise our January project will be all about you again.
Warm regards,
Michal

Project of the November 2025 | Majoris
Engagement & Wedding Rings made of 18K White Gold with a 9ct Radiant-Cut Diamond
Not a 3-carat, not even a 5-carat — but a 9-carat stone!
A client approached us with a dream of an exceptionally large diamond in a bold, statement design. Finding the right stone took months, but once we sourced the perfect gem, the creative journey could begin.
Our design expert, Tam, developed an extraordinary concept — thank you, Tam, we truly admire your vision. The final piece features 22 baguette-cut lab-grown diamonds totalling over 5 carats, while the 9-carat centre stone remains the commanding heart of the design.
With over 20 years of experience, our master goldsmith Jacob brought the concept to life with remarkable precision. It was an honour to create this piece, proudly named after one of the largest stars in the universe, VY Canis Majoris, whose brilliance inspired its creation.

Project of October 2025 | Carina
Pear Cut 5ct. & 5ct. Diamonds
This 18K rose gold ring looks effortlessly elegant, yet finding two perfectly matched 5ct pear-shaped lab-grown diamonds — identical in proportions, clarity, and EX-EX cut — was a rare challenge.
We also needed minimal fluorescence, especially with the chosen E and Fancy Intense Pink colours, which pair beautifully with the warm rose gold band.
Thanks to a client who allowed time for precision, every detail met the highest standard, resulting in a piece of true refined luxury.
Named after the Carina Nebula, this ring reflects its celestial harmony.
What’s your dream piece of jewellery? Share it with us — it may become our next Project of the Month.

"We don't offer dozens of different designs. We only offer a few models, but each one is our unique work and design, of which we're very proud. This represents just a small taste of what we can create for our clients. Additionally, we're fully prepared to design a custom piece for you and make your jewelry dreams come true."
