Luminous petals of prehnite surround a center of darker prehnite. Carnelian, serpentine and green quartz adorn the flower's heart while pearl, crystal quartz and chips of serpentine poise on dainty tendrils. By Nareerat, this elegant brooch is crafted by hand, as she mounts the gems on stainless steel wire. 'My inspiration was a fresh flower corsage,' she confides.
