Material: Silver 925 Stone Type: Opal The main attraction of opal is its unique play-of-color effect, where various colors like blue, green, red, and purple appear to playfully dance within the stone. Like a masterpiece painted freely by a genius artist, the exquisite colors have no identical expressions, each exuding its own individuality. Crescendo Opal is grown in an ideal environment for opals and has almost the same chemical, physical, and optical properties as high-quality natural opal. It is also less prone to cracking because its moisture balance is more stable than natural opals. Opals are popular for their shimmering beauty, like a drop of water containing a rainbow. Their fantastical colors are unique, allowing you to enjoy a one-of-a-kind brilliance. Also, opals are very rare due to their low production volume. They have a clear, water-like base color, and their vibrant play-of-color shines like a rainbow after the rain. Color: Gold Shape: Catch/Stud Earrings Scratches/Discoloration: None
