The provenance and ethical source of
these gemstones may also draw attention to them. In today's gem industry,
traceability and ethics are two of the most crucial
factors. Because most of them are mined in Australia, every stage of the process should
be traceable with continuous information throughout the process. The country's rare and
ethical gemstone mines also produce some of the world's most beautiful blue-green
sapphires.
Because of its relatively new emergence on the gems market, teal
sapphires have not experienced a major price increase as a result of its quiet global
marketing awareness. As a result, they are way less expensive than blue
sapphires with cornflower or royal blue colors. Finally, teal sapphires are notable for
their absence of treatment - at least in the majority of cases. If they do need to be
heated, the process is shorter than that of any blue sapphire heating treatment.
