PLATINUM PT850 4.50 CARAT DIAMOND STARBURST CLUSTER AND SOUTH SEA PEARL DROP CONVERTIBLE EARRINGS - CIRCA 1960s-1970s

You are bidding on a magnificent pair of vintage platinum diamond and South Sea pearl convertible earrings, representing the pinnacle of mid-century fine jewelry craftsmanship. These exceptional earrings feature 4.50 carats total weight of round brilliant and tapered baguette diamonds set in platinum 850, paired with large luminous teardrop South Sea pearl drops. Uniquely, these earrings are fully convertible and may be worn three different ways, offering extraordinary versatility for a piece of this caliber.

THREE WAYS TO WEAR

This convertible design allows the earrings to be worn as:

1. Full Drop Earrings: The dramatic complete look, with the diamond starburst cluster tops suspending the South Sea pearl drops below via a vertical bar of three graduating round brilliant diamonds, for a total earring drop of exceptional presence.

2. Diamond Cluster Tops Only: The starburst cluster tops worn alone as bold statement clip earrings, showcasing the full fireworks design in its own right.

3. Pearl Drop Earrings Only: The large teardrop South Sea pearls worn alone suspended from a simple two-diamond platinum post setting, for a refined and elegant everyday look.

DIAMOND CLUSTER TOPS

Each cluster top is designed in the classic mid-century starburst or fireworks style, with a central grouping of round brilliant diamonds surrounded by a dramatic radiating spray of individually set tapered baguette diamonds fanning outward in every direction. This design was the height of fashionable fine jewelry in the 1950s and 1960s and remains one of the most sought-after vintage diamond earring forms for its theatrical brilliance and movement. The total diamond weight across the full earring set is 4.50 carats. The diamonds appear white and bright to the eye, consistent with G-H color and VS-SI clarity range. The cluster tops are fitted with omega clip backs with posts, allowing wear by both pierced and non-pierced ears.

SOUTH SEA PEARL DROPS

The pearl drops are large, beautifully matched teardrop South Sea pearls displaying the characteristic deep, satiny luster and cream-white body color with subtle warm overtone associated with the finest South Sea production. South Sea pearls of this size and quality are among the most prized and valuable cultured pearls in the world, produced by the Pinctada maxima oyster in the waters of Australia, Indonesia, and the Philippines. These pearls have excellent luster and skin quality.

METAL AND HALLMARK

The earrings are stamped PT 850 — Platinum 850, indicating 85% platinum purity. This hallmark was the standard Japanese platinum designation and, combined with the South Sea pearl drops, places these earrings firmly within the tradition of Japanese fine platinum jewelry that flourished from the 1960s through the 1980s. Japan was — and remains — the world's premier center for South Sea pearl cultivation and pearl fine jewelry production.

PERIOD

The starburst or fireworks diamond cluster design was the defining earring style of the mid-century period, at its peak popularity from the late 1950s through the 1970s. The use of tapered baguette diamonds radiating from a round brilliant center was favored by the great jewelry houses of Paris and New York in the post-war decades, and this style was subsequently adopted and refined by Japanese platinum jewelers during the 1960s and 1970s. These earrings are consistent with fine Japanese platinum production of circa 1965-1975.
