Ethiopian Opal Rough - Per Gram

Our Ethiopian opal rough is offered in two different grades. Grade A has the most consistent flash with deep colors you would expect like turquoise, deep blue and sometimes yellow and orange. Grade B is great for someone new to cutting opal. There is still flash but not as deep. Please note Grade A is pictured. Sold by the gram. Please leave notes like "looking for one piece, need plenty of flash" etc.
