Named after the brightest star.
Sirius Jewellery designs and makes diamond jewellery in the Czech Republic — engagement rings above all, each named after a star or constellation and stamped with a small star inside the band.
Design, diamonds and craft
Every design begins as a drawing and a precise 3D model, engineered for comfort, durability and the way light enters the stone. Pieces are cast in 14K or 18K gold or platinum and finished by hand.
We work with natural and lab-grown diamonds alike. Centre stones are supplied with a GIA or IGI certificate; melee is typically E–F colour, VVS–VS clarity, set one by one under magnification.
Sirius is part of the same family as LaboratorniDiamanty.cz, one of the Czech Republic’s leading diamond specialists — which is where our stones, and our expertise, come from.
