Boulder Opal Gemstone Loose 0.96 CT

Precious opal with beautiful flickering neon colors.
Its brilliance is called play-of-color, and it sparkles with unique colors and patterns.

Among such precious opals,
Boulder opal is a distinctive gemstone.

Boulder opal is formed when water seeps into cracks in iron ore and the like,
forming a thin layer of opal.
The crystals, which retain their natural shape together with the host rock, are mystical.

The boulder opal you are viewing
is a single stone with a precious reddish play-of-color as its main feature.

Generally, green play-of-color is said to be more common,
and there is a theory that the color changes depending on the size of the silica spheres,
which are said to produce the play-of-color.

Like an opal, when the crystal is tilted,
it shows various expressions.
