SvenskaSirius Jewellery – a unique jewellery collection you will find only with us
Sirius Jewellery is a collection of engagement and wedding rings, earrings and pendants designed to let the diamond shine and the piece last for generations. ULTIMATE-GEMS s. r. o. is its exclusive retailer – every piece is handmade in the Czech Republic and set with a lab-grown or natural diamond of your choice.
You choose the metal (14K / 18K gold or platinum), the size and the centre stone directly with the piece in our configurator. Engraving is free and every piece comes with a diamond certificate.
Why Sirius Jewellery
Sirius Jewellery is a collection we offer exclusively in the Czech Republic. It was created with one idea in mind: the diamond should be the star and the piece should last a lifetime. That is why the rings have clean lines without unnecessary ornament, solid settings with prongs that protect the stone, and comfortable band profiles for everyday wear. Engagement rings, wedding bands, earrings, pendants and bracelets match each other, so they can be combined into sets.
How a piece is made
Every Sirius piece is handmade to order in the Czech Republic according to your configuration: you choose the metal (14K or 18K gold in white, yellow or rose, or platinum), the size and the centre diamond – lab-grown or natural, always with an IGI or GIA certificate. The side stones are set by hand by a goldsmith, then the piece is polished and inspected. Production usually takes 2–4 weeks; engraving inside the band is free of charge.
Stones, warranty and service
For every model you can choose between lab-grown and natural diamonds of the same quality (colour E–F, clarity VVS–VS for side stones). Each piece comes with the certificate of the centre stone, luxury packaging and insured GLS delivery. Ring size can be adjusted free of charge after delivery, and we will clean the piece and check the settings whenever you wish. The complete overview of models with prices is in the PDF catalogue; individual categories are in the jewellery catalogue.
