18k Herbert Rosenthal Sapphire and Diamond Bee

I have been lucky enough to have a couple of Herbert Rosenthal bees come through my door and they never disappoint. This beauty is set with rich blue spaphires, with a sparkly diamond in the center and ruby eyes. As with all true Herbert Rosenthal, she's 18k. She weighs 3.71 grams and measures approximately 18x20mm.
