"Synthetic gem manufacturing has unraveled many of nature’s mysteries"

Silica is an important element for opal. According to GIA, in order to be opal, a material must be silica in composition as major elements, possibly containing some water. Thus, the percentage of silica in composition determines man-made opal's quality and value.

PRODUCT TYPE

There are different kinds of man-made opal in the market with different quality. In this website, we will focus on the introduction of lab-grown opal (synthetic opal) with high percentage of silica.

Natural Opal

* Common feature of vertical fire

Opals found in thin fractures in basalt from Honduras commonly show pronounced banding that marks the horizontal level. Play-of-color bands have a vertical, columnar shape that corresponds to digit pattern development. Field of view: 6 cm. Photo by B. Rondeau.

Synthetic Opal

* Common feature of vertical fire

Lab-grown synthetic opal is a kind of precious synthetic gem created by advanced technology. Vertical fire created from the growing process over time is the feature of lab-grown synthetic opal. Among all man-made opals, only from lab-grown synthetic opal you can find this unique vertical growth pattern. It indicates a higher quality with higher value than the others.
