A single stone whose play of color changes dramatically depending on the viewing angle!
Boulder Opal 0.48 CT

　RECOMMEND　POINT
　　　　While at first glance, the play of color seems to be predominantly red,
from another angle, an aurora-like green appears!

It is one of the precious opals that exhibits play of color,
and is mainly said to be produced in Queensland, Australia.

Boulder means "large rounded stone" in English, and
it is named after how it is produced in a massive form.

It is one of the popular opals because its play of color stands out against a dark gray or black matrix.

By the way, the play of color that appears in opals is a very attractive special effect,
but do you know why it appears?

It appears because when light hits substances called silica spheres inside the opal,
a physical phenomenon called "diffraction and interference" occurs.

These silica spheres also greatly influence the coloring of the play of color,
and it is said that smaller silica spheres result in blue hues, medium-sized ones in green, and large ones in red hues.

And since medium-sized ones are common in nature, red and blue play of color are considered rare.

This boulder opal has beautiful and rare red play of color.

It can be said to be a very beautiful stone with shimmering play of color against a dark background.

Also, the attractive point of this stone is that when you change the angle,
it changes from a reddish hue to a coloring primarily of blue and green.

This boulder opal offers two delights in one stone.
How about adding it to your collection?
