Wyoming Field Nobby is well known for looking a little average on the outside yet generally producing something great on the inside.
This nobby is no exception with its hazy blue top and black potch line down the bottom.
We have a 50/50 chance of this cutting a decent gem, so let’s get underway!
Wyoming Field Nobby
Let’s chat about the Wyoming Field for a second.
Where is it?
The Wyoming Field is located about 25 km north-west of Lightning Ridge in NSW, Australia.
The nobby’s found in this area are known to be full of surprises and you never really know what you’re going to get.
They generally have a white cap or a milky top with a color bar and potch around the bottom.
This particular nobby opal was found at the 15-20 feet mark below the earth’s surface.
Did it cut a worthy gem?
Unfortunately, it hasn’t cut a gem that I would usually cut from a Wyoming Field Nobby.
But I am super happy that it did cut a nice opal and wasn’t a complete fail.
It’s what you call a commercial opal, it has a nice color and is more affordable.
If I only showed you the winners we cut then you wouldn’t get a realistic view of how opal turns out most of the time.
We finished with a 4.87ct Black Opal for US$1200.00, you can find it here.
