Miyuki has come up with replacements for DB502, and DB509 through 513. These were made with a rhodium plating.
Miyuki stopped producing them a few years back when price of rhodium became too high. They have now come up with
the same colors in a palladium plating. View Miyuki's color scans: http://www.miyuki-beads.co.jp/english/seed/12.html
As soon as the new colors become available, we will start replacing the original rhodium colors, with the new
palladium ones.
The numbers will change, here is a list of the old and new numbers:
DB502-->DB541
DB509-->DB542
DB510-->DB543
DB511-->DB544
DB512-->DB545
DB513-->DB546
They are also replacing DBC-502 with DBC-542 for the same reason.
