Overview

An ornate cross pendant crafted in 18-karat white gold, channel-set with six step-cut natural emeralds and centered by a round brilliant diamond. The mounting features extensive engraved foliate/scroll detailing along the borders and sides, suspended from an Italian 18K white gold wheat/rope link chain.

Story

Mined in the lush mountains of Boyacá, Colombia, these vibrant green emeralds were hand-matched and set into an intricately engraved Italian 18K white gold cross.

Maker / Origin

The chain bears the official Italian hallmark '750' (designating 18-karat gold) alongside 'ITALY', pointing to the renowned goldsmithing centers of Vicenza or Arezzo. Italian workshops in the mid-to-late 20th century were celebrated worldwide for marrying classical Renaissance engraving motifs with fine gemstone setting.

Condition & Value

Very good vintage condition. Natural inclusions ('jardin') are visible within the emeralds, typical of natural Colombian beryl. Clasp and bail are intact and functional. Excellent preservation helps retain top value.

Market Analysis

Comparable demand stays strongest where maker, originality, and venue confidence line up. Broader examples still trade, but the range tightens quickly when provenance, condition, or selling lane fit is missing.

Value Drivers

  • Strong maker attribution with credible period details
  • Better-than-average condition for the category
  • Broader demand rises when presentation and finish feel intact

Concerns

  • Decorative-only demand limits the ceiling
  • Surface wear or missing provenance can compress the range fast
  • Regional sale lanes often underperform specialist venues
