Black Nickel is LE50 with sandblasted background.

Gold Plated is LE25 and loaded with glitter.

Pastel Variant is LE25  soft enamel, with rainbow metal plating, glow, sandblasted background, and epoxy.

Due to the complexity of these designs and the enamel being filled by hand you may find a flaw even in standard grades, but I have inspected them and more noticeable flaws are considered B Grades, which aren’t in this listing.
