Tandon Gems

Start
with the
stone.

Faceted and smooth gemstone beads, sold by the strand, to anyone who wants to make their own jewelry and to the designers who make it for others. Every listing tells you the stone, the shape, the size and the cut.

Sparkle your dream

Where craftsmanship meets authenticity.

Tandon Gems is a trusted name in gemstone beads. We specialize in precious and semi-precious beads, faceted and smooth, in a wide range of shapes, colours, sizes and stone varieties, and every strand is chosen by hand to a consistent standard.

Every gemstone tells a story. Our job is to supply authentic, responsibly sourced beads that help designers, artisans and gemstone lovers bring their ideas to life. About us

Precious and semi-precious, on the same shelf.

Precious is the traditional label for ruby, sapphire and emerald. Semi-precious covers everything else, including some of the rarest stones we stock. We use both labels because buyers search by them, not because one shelf is better than the other.

Come see them in person.

We bring the full strand wall to every show. Come pick strands in person, or reserve online and collect at the booth.
