Ametrine is natural quartz in a combination of purple and yellow (amethyst and citrine) hence the name.
Sometimes, the gemstones have clear yellow and purple areas, sometimes the purple is 'warmed' by the yellow undertones as seen in these gemstones.
The oval nuggets are faceted and have embossed pendants attached. Those are hand-cast here in Australia out of high quality pewter.
The ametrine ovals are topped with silver beads and tiny citrine beads before they are attached to secue lever back ear wires (stainless steel). Those ear wires are wire wrapped with amethyst beads.
Total length is 7.5cm.
