The floating flowers in jadeite are formed by internal minerals and pigments, and are naturally formed. These flowers usually exhibit green or blue bands of color, which take on a distinctive texture in the more transparent parts of the jadeite.
The floating flowers in jadeite were formed in hundreds of millions of years of geological time and are the result of the combined action of many complex factors. During the formation of jadeite, a solution containing pigments will penetrate into the interior of the jadeite, and over time, the minerals and pigments in these solutions will crystallize and solidify inside the jadeite, forming floating flowers. 
Since the formation of floating flowers requires specific conditions and processes, each piece of jadeite is unique. They vary in shape, color, distribution, and texture, which is one of the attractions of jadeite flowers. 
Although the floating flowers in jadeite are naturally formed, not all jadeite will have floating flowers. Some lower-quality jadeites may not have obvious flowers, while some higher-quality jadeites will have beautiful flowers, which needs to be judged on a case-by-case basis. 
Overall, the floating flowers in jadeite are naturally occurring and are unique textures formed by the minerals and pigments inside. Since each piece of jadeite is unique, they have become a sought after object for many collectors and jewelry enthusiasts.
