I always call them a 1690 - 16 from the back and 90 from the front
Initially when I seen this stuff I absolutely loved it but I think it’s so expensive for what it is and I bought a bracelet that really discoloured quickly which put me off. Also I was in awe because I thought all of the bits were made there but I think they are bought in and just put together? Could be wrong in that one though.
Aha I was right then, she just assembles the bits then? Sure anyone could do that, very disappointing. And as you say it’s really expensive
