This necklace is made up of three pierced and hand engraved Argentium silver sections, 2-layers of 14k gold overlay on the flowers, a fiery multi-color Andamooka Gem Matrix opal set in a 22k gold bezel, 14k gold granulation and flush set diopside accents. The opal used in this design is among my favorites cut by Mark.... it has intense fire and strong color saturation in blue, red and green. The diopside accents are some of the brightest green gems I've ever seen.
