Over 2000 Unset Coober Pedy Crystal Opals

Hello.
We were gifted 750 cwt of vintage 1979 C. P. light crystal light opals that were purchased at a NYC US Customs auction. They have been well cared for, zero crazing 38 years later. Not being jewelers, we are interested in entertaining offers or ideas for selling the entire collection outright. They may be seen at www.opalsonly.com . We welcome any offers or suggestions.
Thank you!
