A fine Retro comet brooch worked in 14K yellow gold and set with diamonds and blue sapphires. The comet's head and a portion of the tail are saw-pierced, a treatment that considerably lightens a design that would otherwise be too massive. The center of the brooch is set with a marquise-shaped plaque worked in white gold and bead-set with round brilliant- and single-cut diamonds. The plaque is surrounded by a cluster of prong-set round brilliant-cut sapphires. The diamonds are estimated at J color, SI clarity. The sapphires have a slightly violetish-blue color, with strong saturation, moderate tone, and very good brilliance. Comet jewelry has been popular for hundreds of years, and usually become fashionable whenever a particularly notable comet passes close to Earth. The back is marked "14K" and has an unknown maker's mark.
