Holley Blue Agate dangle earrings

Two lovely 10x14mm Holley Blue Agate cabochons,  mounted in sterling silver with rhodium plating. 
Simple yet elegant,  these earrings are very eye-catching. 
Holley Blue Agate is world renowned for its delicate lavender tone with peach accents. It's also very rare since the collection site was bulldozed over about 30 years ago, and no new material has been available. 
The stones have some banding and inclusions, adding a unique touch to these earrings.  There will never be another pair exactly like these. 
Each caboshon weighs over 10ct. These are not small earrings.
