Overview This is a sophisticated estate-quality necklace featuring a lustrous strand of most likely Akoya cultured pearls. The piece is defined by its exceptional artistry, specifically its heavy 18K yellow gold clasp adorned with precious gemstones.

The Clasp & Gemstones

• Metal: Solid 18K Yellow Gold, hallmarked "750 T".
• Accent Stones: The clasp is set with vivid green stones (possibly emeralds) and natural brilliant-cut diamonds, adding a layer of luxury and high-contrast color to the classic pearl aesthetic.
• Craftsmanship: The "750 T" hallmark signifies high-purity gold typically found in luxury or designer jewelry pieces.

Pearl Quality

• Type: Lustrous Akoya cultured pearls, known for their deep mirror-like shine and nearly perfectly round shape.
• Color: The pearls display a creamy white body color with desirable overtones.

Specifications

• Total Weight: 38.47 grams (substantial for this length).
• Length: 13 inches when closed (Classic Choker length).
• Condition: Very Good vintage condition; the pearls maintain high luster and the clasp remains secure.

Expert Note: The "750 T" mark is a strong indicator of European or high-end boutique origin. A necklace of this weight (nearly 40g) suggests a very thick-walled gold clasp and high-quality, dense pearls.
