Dear Lee Love,
All the Earth's minerals produce gemstones. The qualities that
distinguish those of great value from run of the mill industrial grade
material are freedom from flaws, resistance to wear, optical clarity,
high reflectivity, high dispersion, optimum colour and size.
Best regards,
Ivor Lewis.
