Cosmo Jewellery is owned and operated by Scott Coggan, an Opal artisan with over three decades in the Opal industry, having cut, valued, wholesaled and retailed Opal in that time.

The Plating process -

Jewellery is plated first, before setting the opal (as the plating process can damage the opal).

All Rhodium-plated jewellery pieces use flash Rhodium-plate within 0.03mm, 0.01-0.02 mmm.

All Gold-plated jewellery is flash Gold-plate with 1 micron for rings, and 0.5 microns for pendants and earrings.
