Item details

Nice slice of Australian Opal with a great variety of opal pockets all across this slab. The matrix alone is beautiful and the opal adds to the appeal of this slab. This slice has one small healed fracture at the very edge of the slab and a couple small pits but overall is a great slice giving you endless opportunities for some very nice cabochons. The stone did shift during cutting so there is a cut thickness difference about in the middle on one side (see the pictures). Our slabs are generally shown wet to show the eventual polished potential, though this slab was photographed indoors and has some dry and some pictures are shown damp. The stone has been left natural with no treatments or fillers. Slabs are sold 'as is' as shown in the photos and are not substituted. A nice slice of beautiful Australian Opal (suspected to be Koroit) ready for the artist's eye to transform from slab to cab with fantastic possibilities.

This slab weighs 43.8 grams (219.0 carats) and measures 10 cm x 5.5 cm x 5.4 mm on the thick end and 4.4 mm on the thin end. Measurements are approximate and are measured from the widest or longest points of the stone; thickness is measured in the middle. Australian Opal carries a hardness of 5.0 to 6.0 on the Mohs scale of hardness.

Koroit Opal is from the mining district of Paroo Shire in South West Queensland, Australia. Here, in the Winton Formation, the opal is found in small concretions. Originally discovered in 1897, the opal did not become popular until 1972. Today, it's a new and unique form of opal that gives a stunning display for the wearer and is not duplicated piece to piece, offering a unique experience for each stone.

Natural stones almost always contain surface impurities like fissures, vugs, fractures (healed or fresh). We try to note if there are any surface features you should be aware of and won't knowingly sell a stone without disclosing in the description of such. We try to list pictures showing all surface features or post information if there are surface features you should be aware of.


Please inspect your stones prior to your use to avoid unexpected breaks later. It breaks my heart to see my husband test a slab by putting pressure to a suspected weak spot and sometimes snaps a slab (if it has a weak spot), but, if you don't test it, half way through your cabochon, it could naturally split on you. Better to remove all doubt before starting.

We don't alter the colors in our photographs, though digital photo colors vary between cameras and depending on the lighting where the photos are taken so please view all photos before purchasing. Naturally lighted photos will be provided whenever possible, but some photos are taken indoors. Photos of this piece were taken indoors with some wet and some dry. My apologies for any glare on any of the photos and the flash has a tendency to wash the colors, therefore, some photos may be with or without flash trying to capture the most lifelike appearance.
