Description from the seller

PERNA LABORATORIO ORAFO — HANDCRAFTED RHODIUM-PLATED 925 STERLING SILVER SCULPTURAL RING WITH 6 MM SAPPHIRE AND 104 NATURAL DIAMONDS

An impressive sculptural ring, handcrafted, stone-set and individually finished by Perna Laboratorio Orafo in Torre del Greco, Naples, Italy.

Its distinctive design is defined by a fluid and asymmetrical sequence of diamond-set curves that wrap elegantly around the central sapphire. The construction creates a refined three-dimensional composition in which the deep blue optical presence of the gemstone contrasts beautifully with the cool-white lustre of rhodium-plated sterling silver and the delicate brilliance of 104 natural diamonds.

The intricate architecture, the large number of individually set stones and the carefully finished transitions between the different curved elements demonstrate the precision and craftsmanship required to produce this jewel.

This is a newly produced artisan piece, individually assembled, stone-set, polished, rhodium-finished and inspected in the Perna Laboratorio Orafo workshop.


JEWELLERY DETAILS

• Maker: Perna Laboratorio Orafo
• Place of manufacture: Torre del Greco, Naples, Italy
• Production: handcrafted new production
• Metal: solid 925 sterling silver with rhodium finish
• Fineness mark: “925”, clearly visible inside the shank and documented in the photographs
• Shank construction: fully closed and continuous
• Design: sculptural, asymmetrical, multi-band spiral architecture
• Ring size: Italian size 16, approximately equivalent to EU size 56
• Total jewel weight: approximately 2.62 g
• Condition: newly produced artisan jewellery


CENTRAL SAPPHIRE

• Gemstone: sapphire, a gem variety of corundum
• Quantity: 1
• Shape: round
• Cutting style: faceted
• Diameter: approximately 6 mm
• Conventional estimated depth used for calculation: approximately 3.60 mm
• Reference specific gravity: approximately 4.00
• Estimated weight: approximately 0.90 ct
• Colour: deep blue, displaying natural-looking tonal variations produced by the facets, internal reflections, extinction and viewing angle
• Setting: mechanically coherent multi-prong setting integrated into the sculptural architecture of the ring
• Geographical origin: not determined by an independent gemmological laboratory
• Treatment information: not determined by an independent gemmological laboratory
• Laboratory report: not included

The estimated weight of the sapphire has been calculated dimensionally using conventional proportions for a round faceted stone:

6.00² × 3.60 × 0.00693 = approximately 0.90 ct

The coefficient used reflects the approximate specific gravity of corundum. Since the sapphire is mounted, its exact depth and physical weight cannot be measured without removing it from the setting. The stated weight must therefore be understood as a prudent dimensional estimate rather than a laboratory-measured carat weight.

The central sapphire is securely held by a multi-prong setting that forms an integral structural and visual part of the ring.


NATURAL DIAMONDS

• Gemstone: natural diamonds
• Quantity: 104
• Shape: round
• Cutting style: faceted
• Diameter: approximately 1.2 mm each
• Conventional estimated depth used for calculation: approximately 0.72 mm
• Estimated individual weight: approximately 0.0063 ct
• Estimated total diamond weight: approximately 0.66 ct
• Setting: pavé-style arrangement with individual setting elements, as documented in the photographs

The individual dimensional estimate has been calculated using conventional proportions for small round faceted diamonds:

1.20² × 0.72 × 0.0061 = approximately 0.0063 ct per diamond

104 × approximately 0.0063 ct = approximately 0.66 ct total

The diamonds follow the sinuous movement of the ring and continue across its sculptural upper sections and shoulders, creating an extensive and evenly distributed brilliance.

No laboratory grades are stated for diamond colour, clarity, fluorescence or cut quality because the mounted diamonds are not accompanied by individual independent grading reports. No unsupported qualitative grades or technical characteristics have therefore been added to this description.


ESTIMATED TOTAL GEMSTONE WEIGHT

• Central 6 mm sapphire: approximately 0.90 ct
• 104 natural diamonds: approximately 0.66 ct
• Combined estimated gemstone weight: approximately 1.56 ct

The combined gemstone weight is a dimensional estimate and must not be confused with the total physical weight of the complete jewel, which is approximately 2.62 g.

The stated carat weights are conservative dimensional estimates calculated from the declared diameters, conventional depth proportions and the approximate specific gravity of each gemstone material.

As all gemstones are mounted, their exact depths and individual physical weights cannot be established without removing them from the settings. Actual carat weights may therefore vary within normal tolerances.

These estimates are supplied exclusively for transparent descriptive purposes and do not replace the weighing of loose gemstones or the findings of an independent gemmological report.


ARTISAN CRAFTSMANSHIP

This ring is not presented as an anonymous industrially assembled jewel. Its construction, stone setting, polishing, rhodium finishing and final inspection were carried out individually by Perna Laboratorio Orafo.

The design requires the precise positioning of numerous small diamonds along complex curved surfaces while preserving the distinctive asymmetrical movement and three-dimensional character of the original composition.

The rhodium finish enhances the bright, cool-white appearance of the 925 sterling silver and creates an elegant visual contrast with the deep blue sapphire and the controlled brilliance of the natural diamonds.

Each example is individually finished by hand. Any minute variations or microscopic traces visible only under strong macro magnification are consistent with genuine workshop production, stone setting and hand finishing and should not automatically be interpreted as manufacturing defects.


CONDITION

Newly produced artisan jewellery.

The ring has been carefully inspected before being offered for sale. The gemstones are mounted and the overall construction is physically stable.

High-magnification photographs may reveal minute surface characteristics, setting details or traces of hand finishing that are not normally visible to the naked eye during ordinary observation or wear.


LOT CONTENTS

• One handcrafted rhodium-plated 925 sterling silver sculptural ring
• One round faceted sapphire measuring approximately 6 mm
• 104 natural round faceted diamonds measuring approximately 1.2 mm each
• One gift presentation box


IMPORTANT INFORMATION

The photographs form an integral part of the description and document the ring’s actual design, proportions, stone arrangement, craftsmanship, condition and clearly visible “925” fineness mark.

Prospective bidders are invited to examine all photographs carefully before placing a bid.

Macro photography greatly enlarges the jewel and may make minute surface characteristics, setting details, handcrafted irregularities or natural optical features appear more evident than they are during normal observation.

The perceived colour of the sapphire may vary slightly according to lighting conditions, viewing angle, screen calibration and the natural interaction of light with its facets.

No statement is made regarding the geographical origin or treatment history of the sapphire because these characteristics have not been established by an independent gemmological report.

The diamonds are declared natural according to the materials used by the professional maker. No unsupported claims are made regarding their colour, clarity, fluorescence, exact cut grade, individual origin or certification.

All dimensions and estimated carat weights are approximate. Exact gemstone weights can only be established by removing and weighing the stones or through appropriate independent laboratory examination.

The Italian ring size is the primary size reference. International size conversions are approximate and may vary slightly according to the measuring system or mandrel used. Buyers are advised to verify the required size before bidding.

The presentation box is included for packaging and presentation purposes.


SHIPPING

The ring will be carefully protected, securely packaged in its gift box and dispatched by tracked courier.

Tracking information will be provided as soon as the parcel has been entrusted to the carrier.

Any customs duties, import taxes, brokerage charges or other destination-country costs, where applicable, are the sole responsibility of the buyer.


A distinctive Italian artisan jewel combining the deep blue optical presence of sapphire, the refined brilliance of 104 natural diamonds and the unmistakable character of workshop-made jewellery from Torre del Greco.
