What are our
Ruby Gemstones?
Using the latest growing techniques, we cut and polish stunning lab grown Burmese colour Ruby. They are made of the same identical molecular properties as mined Ruby.
Each one is unique and has its own inclusions and imperfections as seen in mined Ruby. We call these natures fingerprints.
Note that since each stone is unique the small inclusions are part of their overall appeal and will look slightly different in each setting.
