atural Blue Sapphire Heart & 20 Natural Diamonds – 18 kt White Gold Necklace Solid 18 kt White Gold | Italian Artisan Jewellery | Perna Laboratorio Orafo | Handmade in Italy DESCRIPTION An elegant, individually handcrafted Italian necklace featuring a beautiful heart-shaped natural blue sapphire, surrounded by 20 natural diamonds and mounted entirely in solid 18 kt white gold. Created by PERNA LABORATORIO ORAFO, an independent artisan goldsmith's workshop located in Torre del Greco, Italy, this distinctive creation combines traditional Italian craftsmanship, refined proportions and the timeless appeal of precious gemstones. The necklace features a delicate 45 cm solid 18 kt white gold chain, complemented by an elegant heart-shaped pendant also crafted entirely in solid 18 kt white gold. At the centre of the pendant is a natural blue sapphire, fashioned into a faceted heart measuring approximately 7 × 7 mm. The gemstone displays attractive deep-blue tones, enhanced by reflections from its faceted surface. The sapphire has undergone thermal diffusion treatment, expressly disclosed in this description. The central gemstone is secured within a white gold setting and surrounded by a luminous halo of 20 natural round diamonds, each measuring approximately 1.20 mm in diameter. The diamonds have an estimated combined weight of approximately 0.15 carats. The heart-shaped diamond halo enhances the sapphire's blue colour while contributing brilliance and refinement. The combination of polished white gold, natural diamonds and the intense blue gemstone creates an elegant and harmonious jewellery composition. The heart-shaped design adds a romantic character, while the balanced proportions make the necklace suitable for special occasions and elegant everyday wear. An individually handcrafted Italian creation for admirers of traditional goldsmithing, natural gemstones and distinctive jewellery.

The heart-shaped silhouette creates an elegant focal point, complemented by the bright white gold mounting and surrounding natural diamonds. The gemstone measures approximately 7 × 7 mm. The indicative weight of approximately 1.40 ct is based on dimensional references for heart-shaped sapphires of comparable measurements and typical cutting proportions. Since the gemstone remains mounted and its exact depth has not been measured, the actual weight may differ from this estimate. The stated sapphire weight is an approximate dimensional estimate and not a directly measured or laboratory-certified carat weight. No unsupported claims are made regarding geographical origin, laboratory colour classification or clarity grade. IMPORTANT SAPPHIRE TREATMENT DISCLOSURE THE NATURAL BLUE SAPPHIRE HAS UNDERGONE THERMAL DIFFUSION TREATMENT. This treatment is expressly disclosed for complete transparency. Thermal diffusion is a gemstone enhancement process used to modify or enhance the colour appearance of sapphire. It is distinct from conventional heat-only treatment. The gemstone is not represented as untreated or merely conventionally heat-treated. The precise diffusion technique and depth of colour penetration have not been independently established. The treatment information is provided in good faith according to the seller's knowledge of the gemstone. No unsupported claims regarding the treatment technique or geographical origin are made. NATURAL DIAMONDS - Gemstones: Natural diamonds - Quantity: 20 - Shape: Round - Approximate diameter: 1.20 mm each - Estimated individual weight: Approximately 0.0075 ct - Estimated combined diamond weight: Approximately 0.15 ct - Origin: Natural, not laboratory-grown, according to the seller - Arrangement: Heart-shaped halo surrounding the sapphire DIAMOND WEIGHT INFORMATION The estimated diamond weight has been calculated using dimensional references for round diamonds of comparable diameter and typical cutting proportions. 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 according to 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. COMBINED GEMSTONE WEIGHT - Natural blue sapphire: Approximately 1.40 ct - 20 natural diamonds: Approximately 0.15 ct - Total indicative gemstone weight: Approximately 1.55 ct The combined gemstone weight is based on dimensional estimates and does not constitute a direct weighing or independent gemmological certification. 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 is crafted entirely in solid 18 kt white gold, combining a delicate chain with a carefully designed heart-shaped pendant. The natural blue sapphire is secured within a white gold setting, surrounded by 20 natural diamonds arranged along the heart-shaped perimeter. The decorative diamond halo enhances the central sapphire, creating an elegant contrast between the intense blue gemstone and the luminous white gold and diamonds. Particular attention has been given to the relationship between gemstone proportions, setting construction, precious-metal finishing and overall design. 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 METAL, WEIGHT AND FINENESS SOLID 18 KT WHITE GOLD – 750/1000 Both the necklace chain and heart-shaped pendant are manufactured in solid 18 kt white gold. - Metal: 18 kt white gold - Fineness: 750/1000 - Chain length: 45 cm - Total necklace weight: 2.81 g - Indicative 18 kt white gold alloy weight excluding gemstones: Approximately 2.50 g PRECIOUS-METAL WEIGHT CALCULATION The estimated combined gemstone weight is approximately 1.55 ct, equivalent to approximately 0.31 g. The indicative precious-metal weight is therefore calculated as follows: Total necklace weight: 2.81 g Estimated gemstone weight: 0.31 g Indicative 18 kt white gold alloy weight: 2.81 g − 0.31 g = approximately 2.50 g. This figure is a calculated estimate, not a separate direct weighing of the precious-metal components. Since the gemstones remain mounted and their actual weights have not been independently established, the calculated gold alloy weight is provisional. The calculation assumes that the remaining necklace components consist entirely of 18 kt white gold. The stated alloy weight must not be confused with the weight of pure gold. COMPLETE NECKLACE Total weight: 2.81 grams, including the chain, pendant and all mounted gemstones. The accompanying weighing photograph documents the complete necklace with a total weight of 2.81 g. The necklace is described as solid 18 kt white gold jewellery, not gold-plated or silver jewellery. CONDITION AND PHOTOGRAPHIC DOCUMENTATION The necklace is offered in the condition shown in the accompanying photographs.
