14x10 Holley Blue Agate Cabochons

These cabs are aprox 14x10mm (but slight variations because they are handmade). Though some weigh as much as 7ct and some as little as 4.5, the average weight is 5.5ct each. 
Some have a higher dome or  more distinctive color or banding, etc. 
If you're not familiar with Holley Blue,  it was found near Sweethome OR in the past, but the collection site has been closed for about 35 years.  If you've got Holley Blue now, it's extremely rare and getting rarer every day.
