The 30.5-inch necklace alternates sections of carved rock crystal quartz beads with round carved black onyx stations connected through 18K yellow gold chain links. The transparent rock crystal beads display faceted carving creating light refraction while the polished black onyx beads provide dramatic color contrast. The design culminates in a 3.5-inch tassel featuring diamond-set gold cap with carved rock crystal and black onyx bead fringe strands. Multiple full-cut diamonds totaling 0.85 carats accent the tassel cap and connector elements throughout the necklace. Gold elements have tested consistently as 18K yellow gold.
About Rock Crystal and Onyx Jewelry
Rock crystal quartz and black onyx represent classic gemstone combinations in fine jewelry, offering stark color contrast between transparent colorless quartz and opaque black onyx. Carved beads demonstrate traditional lapidary techniques creating faceted or smooth surfaces that enhance each material's natural properties. At 174.40 grams in solid 18K yellow gold with 0.85 carats of G-H-I color SI clarity diamonds plus numerous carved gemstone beads, this necklace delivers substantial luxury presence and investment-grade materials.
Condition Notes: Overall very good condition. Black onyx beads in tassel measure approximately 7.50mm while larger beads along necklace measure approximately 14.50mm. Multiple areas tested consistently as 18K gold.
