In Australia, opals that are visible within a matrix of limonite (brown iron ore) and other materials are called "boulder opals." The vibrant opals within the opaque matrix are very attractive, and even small beads are traded at very high prices. This time, we have obtained large tumble-cut beads with popular colors such as blue and green. We will offer them at a special price, so please consider them. (Number of beads) 1 (Size of beads) Approximately 26 x 15 x 8mm Processed to take advantage of the natural shape. Please be sure to understand this before purchasing. * You can enjoy the play of color more by shining light from a smartphone or other source.

If you have any questions, please leave a comment and we will answer, but we will reply late at night on weekdays due to work.
