Opal

Opal is an English gemstone name taken from the precious stone, which itself derives from the Sanskrit upala meaning 'precious stone.' The opal is celebrated for its play of color — shifting through the spectrum depending on the light — making it a rich metaphor for a pet with a dynamic, multifaceted personality.

Opal is having a quiet renaissance, showing up in both baby name lists and pet name registries with equal momentum. It has an old-fashioned sweetness undercut by something genuinely luminous — like the stone itself. For a cat, it is almost perfect: opals shift and shimmer and are notoriously difficult to fully understand, which describes most cats exactly. For dogs, it carries a gentle, vintage charm that suits a calm, affectionate companion. The name works beautifully for any animal with striking or unusual coloring, particularly those with iridescent, multi-toned, or simply very expressive eyes.
