Four opals set along a 10k band with diamonds worked into the gaps between them, so the row runs stone, spark, stone, spark for the full 17mm across the finger.

What sold us was the rhythm of that setting. The diamonds fire hard and the opals turn colour beside them, which keeps the whole row moving as the hand does. Size 7¼, and she stacks beautifully against a plain band, though she holds a finger on her own.
