OPALS, like pearls, have been around for a long time.
And similarly, they tend to get a bad rap for being daggy or underwhelming due to low quality mass production.
This Sunday Gecko Valley Winery is holding a seminar showing a variety of the queen of gemstones.
The winery's jewellery-designer Miranda Manifold will be present.
The jewels and winery owner Coleen McCray said consumers need to be savvy when ensuring they're getting quality.
"Unfortunately Australia has a reputation for 'tourist opals' which are triplets," Ms McCray said
"Triplets are normally where a plastic base (has been used) and then it's formed with black onyx, with a photograph or a tiny piece of opal over the top."
There will be unique earrings, rings and pendants available for sale on Sunday as well as loose stones ready to be made into something special.
"It's a chance for people to understand and learn how opals can be quite beautiful, and things that people have seen in the past aren't really the ones that they should be looking at," Ms McCray said.
