Black Hills Gold Marquise Green Gemstone and Diamond Ring

This is a vintage-style ladies' ring manufactured by the South Dakota Gold Co., housed in its original branded presentation box. The central focus is a marquise-cut green gemstone, likely a tourmaline or emerald, set horizontally in a bypass-style mounting. The band transition features traditional Black Hills Gold motifs, characterized by delicate tri-color gold leaves in shades of rose and green gold, which are hallmarks of this regional jewelry style. Accompanying the central stone are small round-cut diamond accents nestled within the leaf patterns, adding additional luster to the piece. The shank appears to be crafted from 10k or 14k yellow gold. The item shows signs of light vintage wear consistent with age, but maintains a bright metallic luster. The original box indicates it is part of an 'Authentic Black Hills Handcrafted' collection, suggesting late 20th-century production. The craftsmanship is highly detailed, featuring hand-graved textures on the gold foliage that reflect the artisanal standards of South Dakota jewelry manufacturing.
