How to Identify Opal Diamond Ring?
- Look for the PT900 or PLAT hallmark on the inner band, indicating the 1970s-era platinum setting.

- Verify the play-of-color by rotating the stone under a single light source to see vibrant, multi-directional spectral flashes.
- Inspect the diamond surround for consistent clarity and the specific prong-setting style common in 1970s jewelry.
