VTG Labeled Genuine Fire Opal 4.91ctw 9x7mm Oval Set of 4 Loose Gemstones

*Correction, Brazillian Fire Opal, not Mexician / Jalisco Fire Opal as originally posted. Origin is Brazil.* Family estate owned. MIL was a huge Gem collector. Many boxes still sealed, and some unsealed simply for examination. Never used or applied into Jewelry pieces unless, otherwise noted. Gemstones: Unsure of treatment- if any. 4.19ctw 9x7mm Oval cut, Fire Opals (fully faceted) not cabochon or flat backed. Set of 4. Condition: Excellent, unable to see scratches under naked eye. Box is in good condition. Semi-vintage item so possible wear or tear may be seen on box even if only examined under loupe. Gemstones have not been disturbed since find. My hands aren't shaky, the opals have this odd almost smokey translucence to them on photograph, as well as in person. Yet, they still "spark" under motion and angle. The colors do vary in this set from Yellow to gold to orange. Inquiries, offers and/or bundles are always welcomed. Delivers in brand new packaging, along with the original box they're in. The label is on the back. Forgot to photograph. *****Original label! Thank you. Many other similar boxes, loose stones are on the way as well. Feel free to ask about anything.
