3inches long, shaped like a ship's sail. Gold mount with three small green stones and one big red stone. Huge sentimental value. Lost somewhere between Clonmel St. - Harcourt St. - Hatch St. and the National Concert Hall, Earlsfort Terrace. Reward/ charity donation if found. Grateful for any news. Thank you!
