19th Century Russian Diamond Brooch

Description & Features:

  • Material: Yellow gold with partial silver coating.
  • Weight: Total weight of the brooch is 12.49 grams.
  • Diamonds:
    • 5 larger antique European cut diamonds — Estimated 3.41 ct, Color J-L, Clarity SII-S12.
    • 9 smaller antique cut diamonds — Estimated 1.51 ct, Color K-L, Clarity SII-11.
    • 84 small uncut diamonds — Diameter 1.2-1.7 mm, cutting style "A Rose".
  • Hallmarks/Markings: Stamped with purity mark "56" and a brand mark "JIO", attributed to a well-known Russian assayer (active 1880-1890) and the maker's stamp "HB" (Nikolai Bilibin, 1868-1890).

Historical Significance:

  • This brooch has exceptional provenance, having survived the Bolshevik Revolution. The detailed craftsmanship and materials suggest it was custom-made for a high-status family with ties to the church, reflecting wealth and social standing in 19th century Russia.

Condition: Excellent — The brooch appears to be well-preserved with no evident damage or wear that compromises its integrity or aesthetic appeal.

Estimated Market Value (2024): Given the rarity, craftsmanship, and provenance, this piece is considered a valuable collector's item. Similar Russian Imperial-era diamond brooches have been known to command prices between $8,000 - $12,000 USD or $10,500 - $16,000 CAD at reputable auction houses like Sotheby's or Christie's.

Key Factors Affecting Value:

  • Provenance: The connection to pre-revolutionary Russia and a notable family lineage significantly enhances its desirability.
  • Diamond Quality: The combination of antique European cuts, rose cuts, and uncut diamonds adds distinctive character.
  • Craftsmanship: The gold and silver detail is indicative of fine Russian jewelry techniques from the late 19th century.

Recommendation:

  • For a more precise valuation, I highly recommend consulting a professional appraiser who specializes in antique Russian jewelry. A certified gemologist may also provide additional insights into diamond authenticity and quality.
  • Consider submitting the piece to a reputable auction house such as Sotheby’s, Christie’s, or Bonhams for a detailed valuation and potential sale.
