I cleaned this beauty up professionally and its colors display nicely in the sunlight! (Looks almost Light SCA in the sun!) Underlighting or other bright light seems to wash out some of the Pink color. This is an unembossed Sulminar from Argentina. One tiny base peck from VVVNMint. First email can add this to their collection for only $45 plus shipping. Don't snooze. Thanks Bud!
