Which term describes a series of minute nicks along the facet junctions of a fashioned diamond, giving the edges a white or fuzzy appearance?

• A. Abrasion
• B. Adamantine luster
• C. Aggregate
• D. Alluvial deposit

Answer: (A)

Abrasion is the wear that shows up as tiny nicks and chips along the edges where facets meet. When a diamond’s girdle or facet junctions pick up countless small scratches or chips, light is scattered differently at those edges, giving a white or fuzzy look. This description precisely matches edge wear from abrasion. The other terms don’t describe wear on diamond edges: adamantine luster refers to the stone’s overall brilliant surface, not a damaged edge; aggregate means a collection of particles, and alluvial deposit describes sediment from water flow, not surface damage on a cut diamond.
