Blue and black earrings just seem to make sense. Every boomer gal has black in their wardrobe, and many are drawn to the color blue, hence, sensible earrings. Just like ice cream in the summer or a tropical retreat in winter, cute earrings in black and blue, just go hand in hand. Comprised of faceted black onyx, beautiful quality turquoise, and sterling silver. All metal is solid sterling 925. I formed the circular metal into a concave shape and applied a slight patina for a vintage appeal. The height is two inches.
