Authentic dendritic opal typically showcases a creamy or translucent base color, with dark or rich inclusions that form the characteristic dendritic patterns. The contrast between the background and the inclusions is what enhances its beauty.
Next to consider is translucency. Genuine opal should not be completely transparent or opaque. Instead, it has a milky translucence that adds depth to its appearance. One trick to check is to hold the stone against a bright light; the light should diffuse softy through the opal, revealing its inner patterns without making it appear dull.
Moreover, the patterns themselves are a telltale sign. Each genuine piece displays unique, organic designs that usually appear random. If the dendritic formations look overly uniform or geometric, that could be a sign of imitation.
Common Imitations
Several imitations present challenges for both novice and experienced collectors. One of the most recognized is the use of truthful glass. Glass can mimic the visual qualities of dendritic opal but lacks the same optical properties and characteristics. A simple scratch test may reveal the difference; genuine opal will scratch glass while true glass will not display the same effects.
Moreover, synthetic opal, often labeled as “created opal,” is made in labs and shows significantly different inclusions compared to natural stones. Its patterns may seem vivid and bright but often lack the variation and uniqueness of natural dendritic patterns. Misleading names can muddy the waters—sometimes, stones marketed as dendritic can be quartz or agate dyed to create faux opal appearances.
Testing Methods
To ensure that what you have is true dendritic opal, various testing methods can be implemented. One respected method is the water test. Genuine opal exhibits low solubility in water. If submersed, it should not absorb water, although the weight might change slightly.
You can also perform a UV light test. Real opals fluoresce under UV light while many of the imitations do not. The subtle glow of the stone under this light can indicate authenticity. Always be cautious when using this method, since not all genuine opals fluoresce in the same intensity.
For further verification, consult with gemstone laboratories that provide gemological reports. These assessments typically offer detailed insight into the mineral content, confirming whether your specimen is a genuine dendritic opal or a lesser candidate.
"Knowing how to identify genuine gemstones can elevate your collecting experience. It transforms the hunt into an informed pursuit."
In the end, having the right knowledge about identifying genuine dendritic opal not only adds to the value of your collection but also enhances the joy of connecting with nature’s artistry in gemstones.
