3.00ct Mexican Fire Opal, 1.25ctw Diamond and 18K Yellow Gold Ring - This ring was finely crafted in 18k yellow gold and boasts a 3.00ct (approximate) round cut Mexican fire opal. The opal has a fiery, vibrant yellow-orange color with a unique glowing quality, and you would almost think that it would glow in the dark. This rare gemstone is created in the ancient Mexican volcanoes, when water seeps into the flowing lava, and is becoming increasingly harder to come by. The opal is surrounded by approximately 1.25ctw tapered baguette and round cut diamonds, completing the piece beautifully. Ring size: 7.25. Condition: Overall excellent estate condition with very light signs of wear. (WEIGHT: 7 grams)
