A 6×4mm oval ruby CZ with six white CZ rounds at 1.5mm in a 20×10mm 925 sterling silver cluster setting — the Ruby Cluster is the full-halo treatment for the red stone. The white CZ surround amplifies the ruby's red by contrast, making the central stone appear more saturated than it would in isolation.

At 1g, a balanced charm weight for a cluster of this stone count. The setting is clean and precise, with the CZ halo placed close to the ruby to create a tight, jewellery-grade composition.

For the piece in your charm collection that makes a colour statement without any ambiguity.
