PIA's Third Eye rings are u-shaped (with a flat top), which makes them more forgiving in the way they are sized. Small is recommended for ring sizes 4-5, medium is recommended for ring sizes 6-7. If you are in between sizes, PIA recommends sizing down. Opal is known for its unique display of flashing rainbow colors. The type of opal (Gilson) used by maker Martha Pia is grown in a lab - its low water content makes it stronger and able to withstand high temperatures without cracking. Gold-plated silver band.
