Its elegant shape creates a distinctive focal point, complemented by the warm yellow gold setting and surrounding natural diamonds. The estimated weight of approximately 0.70 ct is based on dimensional comparisons with faceted heart-shaped aquamarines of similar measurements. As the gemstone remains mounted and its exact depth has not been measured, the actual carat weight may differ from this estimate. The stated aquamarine weight is an approximate dimensional estimate, not a directly measured or laboratory-certified value. The gemstone is declared natural according to the seller's information. Its treatment history has not been independently established. Consequently, no unsupported claim of untreated status is made. No specific geographical origin or laboratory quality grades are claimed.

Calculation: 20 diamonds × 0.0075 ct = approximately 0.15 ct. The diamonds remain mounted and have not been individually removed and weighed. Their actual combined weight may vary depending on individual cutting proportions and depths. The stated diamond weight of approximately 0.15 ct is an estimate and has not been independently certified. No unverified diamond colour, clarity or cut grades are claimed.

TRADITIONAL ITALIAN ARTISANAL CRAFTSMANSHIP This necklace was individually created by PERNA LABORATORIO ORAFO, an independent artisan goldsmith's workshop located in Torre del Greco, Italy. The creation combines two different gold finenesses within a single harmonious design. The delicate 18 kt yellow gold chain provides an elegant foundation, while the 14 kt yellow gold pendant features a decorative heart-shaped gemstone composition. The natural aquamarine is secured within a carefully constructed yellow gold setting, surrounded by 20 natural diamonds arranged along the heart-shaped perimeter. The diamond halo enhances the central gemstone, adding brilliance and definition without overwhelming its delicate blue appearance. The refined proportions of the pendant and the elegant gold chain create a balanced composition. Particular attention has been given to precious-metal construction, gemstone setting, proportions and finishing. The necklace reflects traditional Italian artisan goldsmithing and the individual character of workshop production. Its handcrafted nature distinguishes it from conventional mass-produced jewellery. PRECIOUS METALS, WEIGHT AND HALLMARKS This necklace is composed of two solid yellow gold alloys with different finenesses. SOLID 18 KT YELLOW GOLD – 750/1000 Used exclusively for the necklace chain. - Chain length: 45 cm - Chain weight: 1.10 g - Precious-metal fineness: 750/1000 The chain weight was separately determined by the seller. SOLID 14 KT YELLOW GOLD – 585/1000 Used for the heart-shaped pendant, including its gold mounting and suspension components. - Estimated pendant gold weight: Approximately 1.04 g - Precious-metal fineness: 585/1000 The estimated 14 kt pendant gold weight has been calculated by subtracting the separately determined chain weight and the estimated gemstone weights from the total necklace weight. The calculation is: Total necklace weight: 2.31 g 18 kt chain weight: 1.10 g Estimated combined gemstone weight: 0.85 ct, equivalent to approximately 0.17 g Estimated 14 kt pendant gold weight: 2.31 g − 1.10 g − 0.17 g = approximately 1.04 g.
