The atelier
Sirius is the jewellery house of a Czech team of designers, gemmologists and goldsmiths. We draw every design, cast it in solid gold or platinum, and set each diamond by hand.

01 The name
Why Sirius
Sirius — α Canis Majoris — is the brightest star in the night sky. It gave its name to our first solitaire and, later, to the whole collection. Every design since has been named after a star or constellation: Polaris, Antares, Rigel, Mira, Orion, Lyra.
Look inside the band of a Sirius ring and you will find a small engraved star — the signature of the collection.
02 Craft
Made by hand, one piece at a time
Design
Every piece begins as a drawing and a precise 3D model, engineered for comfort, durability and the way light enters the stone.
Casting & finishing
Solid 14k or 18k gold or platinum, cast and finished by hand to a mirror polish.
Hand-setting
Each diamond is set by an experienced goldsmith under magnification — centre stones and melee alike.

03 Diamonds
Lab-grown and natural
We work with both. Lab-grown diamonds are chemically, physically and optically identical to mined diamonds, at a fraction of the price; natural diamonds carry the rarity of billions of years. Your clients choose — we set either with the same care.
Centre stones are supplied with IGI or GIA certificates. Melee is typically D–F colour, VVS1–VS2 clarity.
