This 18k gold ring was made in Russia for the 1980 Olympics that were held in Moscow. The ring reads around the top oval, "MOCKBA-80" with "XXII" in the center and the Olympic Five Rings around the bottom edge. Inside, under the top circle are engravings of the Soviet Union symbol of the hammer and sickle in a star, followed by the numbers "583" and Russian letters "B, K," and "Omega." This item was purchased at auction in Moscow around 1993 or '94, and comes with a LOA.
