Please know that I cannot accept any requests for "live conversations" such as phone calls.I give my best answers in writing when I have time to think about them.Sometimes a "Chat box" will pop-up asking if you would like a live conversation. Please know it is not from me.
If another professional enters our exchanges, feel free to tell them that you are working with me if you wish.
To give you the most accurate value, I should have a photo of the brooch (yes, that is the correct but odd spelling).
Does the piece have any words or numbers?
You may need to use the macro function (flower icon) of your camera to get a good clear photo of your brooch.
To send photos you may use the "attach file" or "add file" in the blue box link on your reply page or the "paper clip" found in the toolbar you see on your reply page.Please do not send in ZIP format. The jpg or jpeg format works best.
On today's market, the average price for an antique opal brooch is $200 - $300. I highly recommend, in lieu of you not having photographs to post here for assessment, that you take it to a local estate jewelry shop and have it inspected in person. A reputable estate jeweler will test the metal and look at the opal under a loupe and determine its carat size for you for no charge. They may offer cash on the spot, however you would not be required to sell at that time.
Bear in mind that an ‘asking price’ is one that has not been sold and a true sale value is an actual past documented sale record.

While to give the best answer with up to date current value, a photo would be very helpful.
Australian opals are much sought after. On my trips there I have collected opal jewelry.
I learned that the more fire they had in them, the more valuable they are.
As a quite large 1" opal surrounded by silver scrolls, your antique opal brooch would have a retail jewelry store value of $400-600 depending on the "fire" in the opal and the location of the retail venue.
Am insurance replacement value would be $550 - 700. A gemologist can tell you the value of the stone but not the antique value of the brooch. Once the stone is appraised, then an you should consult an estate jewelry specialist.
A private seller to a dealer or at auction can expect 30-60% of retail value.
I hope I have helped you.
