Special price! Color: Silver Material: Platinum Material: PT900 (stamped) Ring Size: 12 Weight: 8.16g Black Opal: 0.8ct Diamonds: 0.4ct Sorting report included. Platinum black opal ring. Black opal with vibrant color. Beautiful play-of-color with yellow, orange, green, blue, and purple hues. Stones with this level of color are rarely seen these days. The surrounding diamonds are colorless and transparent, totaling 0.4 carats, enhancing the black opal. Opal is a very soft stone with low hardness. It is also sensitive to ultrasonic cleaners and hot water. The black opal has minor scratches that are not visible to the naked eye, only under a loupe. I think almost all opals have them. The neon effect of the opal is so strong that they are barely noticeable. There are no cracks. This is the best in terms of color and balance among the items I am currently selling! Please consider the above points and refrain from purchasing if you are overly concerned about these details.
