Gorgeous Vintage Estate Mid Century 1970s 18k Yellow Gold Turquoise 0.85ctw Diamond Drop Dangle Earrings. 

The dangle earrings are set with gorgeous turquoise cabochon in a briollete shape. The diamond is brilliant round cut, near colorless and slightly included totaling 0.80 carats approximately. 

The length of the earrings is 40mm long x 12mm wide x 14mm approximately.

Marked "18K"and earrings have been tested for 18k gold purity too. 

This earrings are in very good condition. I reset them from omega earrings to dangle earrings so they are extremely comfortable and a touch more chic / updated. 

Although these are not marked they are identical to another pair I have that is marked "La Triomphe". 

‘La Triomphe’ was the name given to a range of jewelry created by the American firm Astoria Jewelry Manufacturing Company of Long Island, New York, in the 1960's. 

The first recorded use of the name (which was trademarked), accompanied by its distinctive logo of Paris’s Arc de Triomphe, was in June 1965. For the next twenty or so years they created some fabulously bold pieces of cocktail jewelry including rings, bracelets and earrings. Almost exclusively made in yellow gold, the pieces were set with brightly coloured gems such as peridot, amethyst and tourmaline as well as hardstone such as turquoise, lapis lazuli and malachite. The name is no longer in use but the jewelry remains widely collected and appreciated for its vibrant colours, strong designs and vintage aesthetic.
