Through speaking with a shop owner who had been in the business for over 38 years, we learned that, due to the immense rarity of this gem-quality blue chalcedony, it is hardly exported and not commonly known outside of Taiwan.
Consequently, prices are constantly going up as supply dwindles and mines become exhausted – a common story when it comes to rare gems.
With a little further research, we learned that this type of blue chalcedony has slightly different tones, depending on which part of the country it comes from. The colours range from a sea green colour akin to green beryl to a blue-green like Paraiba tourmaline to a green-blue similar to Persian turquoise to a deep blue like that of Cambodian blue zircon.
As with all other types of chalcedony, this type is translucent to opaque and, true to type, the more light it allows through, the more highly prized it is.
We settled on two specimens for our collection – one more green and the other more blue. We hope to return to Taiwan in the near future to explore using this unique gem in a limited series of our jewellery.
