Solid 10K yellow gold with diamond-cut texture at 0.60 inches in diameter is fine jewelry operating at the precise everyday investment sweet spot: the diamond-cut facets across the hoop surface transform the solid gold into a continuous multidirectional shimmer, each tiny cut catching and redirecting the warm gold light from a different angle. At 5/16 of an inch wide with saddle back closure, the hoop has the substantial feel that real gold provides without being oversized or dramatic. The 10K solid gold construction means this earring will maintain its appearance and quality through decades of daily wear. The real gold alternative to the diamond-cut gold-over-sterling hoops in the collection.
