Overview Blue Zircon has fallen out of favour in modern times, partly due to the similarity in name with Cubic Zirconia, the diamond simulant, despite the two being unrelated. But recently it is gaining popularity again. Blue zircon has a wonderful, azure blue colour and great scintillation. This vintage brooch is styled in a sunflower type shape, with a daisy cluster of seven brilliant-cut blue zircons, claw set in the centre and nine 'ribbons' pave set with diamonds. A bold statement brooch - very 'en vogue'.
