Crushed Olive-Green Opal from Madagascar, Coarse Crush, Gravel Size, 4mm - 2mm
Opal is a very common class of minerals that are well known for their brilliant flashy “fire.” However, most naturally-occurring opals are "common" opals, which come in a variety of colors and are generally opaque. This common olive-green opal is from Madagascar and has a beautiful earthy-green tone.
Our coarse material is considered to be pea- sized gravel, ranging between 4 millimeters to 2 millimeters. Please see the corresponding sediment size chart.
