We are currently in the process of adding additional star gems to this page.  We hope to have it completed by March 31st.  Thank you for your patience.


Star gems are caused by fine needle or hollow tube inclusion that are orientated along either a three fold axis (6 ray stars) or two fold axis (4 ray stars).  Natural star gems suffer from being compared to the synthetic Linde star gems commonly found in jewelry which display perfect, 6 ray stars.  In nature, perfection is rare and thus the perfect star is equally rare.
