Alexandrite is a unique stone which varies in colour, but is most commonly a pale purple mixed with hints of grey and blue depending on the light. These pretty stud earrings measure 5mm High x 5mm Wide x 4mm Deep with the crystals themselves measuring 4mm. The rub over setting creates a halo effect around the stone which along with the crystal size will make it stand out in your ears and make a big impact! They weigh 1g for the pair and have 11mm pins.
