This impressive gemstone cluster necklace is destined to turn heads. Crafted in sterling silver, this eccentric choice features a shimmering white topaz accented cluster of multi-shaped and multi-sized blue gemstones - including Swiss blue topaz, sky-blue topaz and lab-created bright blue sapphires. Buffed to a brilliant lustre, this design suspends centred along a 16.0-inch diamond-cut cable chain with a 2.0-inch extender that secures with a lobster claw clasp.
