I recently saw a three strand version of this (which I am still trying to track down for purchase – it’s proving to be a bit of jewellery unicorn) and it is one of those things that looks better on than in a picture. The pave crystals just jump to life under light and the irregular, pebble shape of the beads is a really nice form for this.
From Swarovski’s Atelier Core collection, it sells for USD $770; there are matching pieces available.
