This is a interesting slab of material we call conglomerate or opal nuts in a biscut band.It may be kept as a specimen or you can polish it.This material does have natural holes in it and the sandy areas are hard to polish.In asia the cutters rub fine boulder ironstone [you can collect this in the cutting machine tray by grinding some material away and allow to dry]. They then rub this powder in to the rough and heat it up.Then they apply super glue to it and polish.This gives a good glossy finish.
The Opal Sheriff program allows our members to request an audit on any auction, which is completed by an independent Gemologist who assesses the accuracy of the item description and pictures.
