of impurities in the silica spheres.

these colors are more prized than the others. Some buyers are also known to favor
black background color because it stands out in a dark background.
In addition to that, the play of color is also significant in determining the appearance.
Regardless the color or the combination, the play of color should be vivid.

4. 2. Pattern:
The exact arrangement of the play of color in opal is the color. It can take many
forms. Closely arranged patches are more preferable over tiny color patches.
Moreover, when the colors are bright, the stone becomes valuable. In addition to
that, it is also crucial to check the extinction of dead spots while evaluating the
pattern. Dead spot is referred to a particular area in gem where no play of color
appears and there is visibility of only the background color.
3. Clarity:
Clarity is the degree of transparency and the clarity can range from transparent to
opaque. Different types of opal have different levels of clarities. In crystal opals,
transparency is preferred while in black opal, an opaque background is preferable.
As an individual type of opal, each displays the best background. However, if the
background is cloudy or milky, the value of the stone is lowered. The gem becomes
less attractive and might signal lack of appropriate stability.
There are lots of characteristics in clarity that greatly affect the value of the stone.
Opal can have fractures, pits and other blemishes in surfaces. Moreover, it might
often contain the fragments of its host rock. Lack of moisture can result in the
development of cracks and resemble the web of a spider.
These are top three common factors considered for determining the quality. The
other factors include cut, carat weight and the assembled opals, which are the
doublet and triplet. Knowing these things can help you in a proper buying decision.
