Ring Settings & Mountings

Trellis Setting

The trellis setting is an intricate and visually appealing ring setting that has gained popularity for its ability to securely hold a gemstone while adding a decorative element to the ring design. It is characterized by a series of intersecting metal bands or wires that form a lattice-like structure, resembling a garden trellis. This unique design not only enhances the beauty of the center stone but also provides excellent support.

Definition

A trellis setting is a type of gemstone mounting where the metalwork consists of a crisscrossing network of bands or prongs that create a supportive framework for the center stone. These metal strands weave together, often forming an open, airy pattern, and grip the gemstone from multiple points. The term 'trellis' aptly describes the structure, evoking images of climbing plants supported by an interwoven framework.

Key Features

Interwoven Metalwork: The defining characteristic is the network of metal bands that cross over and under each other to create a secure cage for the gem.
Open and Airy Design: Many trellis settings have an open structure, allowing light to enter the gemstone from multiple angles, maximizing its brilliance and fire.
Enhanced Security: The multiple points of contact provided by the interwoven metal offer robust security for the gemstone, reducing the risk of it becoming dislodged.
Decorative Appeal: The intricate metalwork itself serves as a design element, adding a layer of detail and artistry to the ring.
Versatility: This setting style can be adapted to various gemstone shapes and sizes, and can be incorporated into different ring styles, from engagement rings to fashion rings.
Light Performance: The open design generally allows for excellent light return, making the gemstone appear more vibrant and sparkly.

Origin and History

While the exact origin of the trellis setting is difficult to pinpoint to a specific date or inventor, its design principles are rooted in the long history of metalworking and jewelry making. Intricate metal weaving and lattice-like structures have appeared in jewelry for centuries, particularly in decorative elements and filigree work. The trellis setting likely evolved as a way to combine the security of prong settings with the aesthetic appeal of more elaborate metal designs. Its rise in popularity in modern jewelry can be attributed to the desire for unique and detailed ring designs that offer both beauty and durability.

Types / Variations

The fundamental concept of the trellis setting allows for numerous variations, primarily differing in the thickness of the metal bands, the complexity of the weave, and the overall design aesthetic.

Classic Trellis: This is the most common type, featuring a balanced crisscross of relatively fine metal bands that create a secure yet open structure.
Thicker Band Trellis: In this variation, the metal bands are more substantial, offering an even greater sense of security and a bolder visual statement. This can also provide a more robust framework for larger gemstones.
Filigree Trellis: This style incorporates delicate wirework and sometimes granulation, drawing inspiration from traditional filigree techniques. It often results in a more ornate and vintage-inspired look.
Bezel-Assisted Trellis: Some designs might incorporate a partial bezel around the edge of the gemstone, in addition to the trellis prongs, offering an extra layer of security.
Openwork Trellis: This emphasizes the airy nature of the setting, with wider spaces between the interwoven bands, allowing maximum light entry.

How It's Made

Creating a trellis setting involves skilled craftsmanship and precise metalworking. The process typically begins with a design or wax model. Jewelers use various techniques:

Hand Fabrication: For bespoke or high-end pieces, jewelers may meticulously shape and solder individual wires and bands together, carefully weaving them to form the desired lattice structure around a cast wax model or directly around the gemstone if it is being set by hand.
Casting: More commonly, a mold is created from a detailed wax model of the trellis setting. This mold is then used in the casting process, where molten metal (such as gold, platinum, or palladium) is poured into the mold. Once cooled, the casting is cleaned, polished, and the gemstone is set.
Prong Shaping: The 'prongs' or metal bands are carefully shaped and bent to conform to the girdle and crown of the gemstone, ensuring a snug and secure fit.
Stone Setting: The gemstone is then carefully placed into the prepared setting, and the metal ends of the trellis structure are meticulously bent or secured over the gemstone's edges to hold it firmly in place. This requires precision to avoid damaging the stone or obstructing its brilliance.
Finishing: The completed ring undergoes final polishing, cleaning, and any additional detailing, such as engraving or the addition of accent stones.

Grading & Quality Standards

While there are no specific grading standards solely for the trellis setting itself, its quality is assessed based on the overall craftsmanship of the ring and the quality of the materials used. Key aspects include:

Metal Quality: The purity and type of metal used (e.g., 14k gold, 18k gold, platinum) are crucial.
Craftsmanship: The precision of the metalwork, the smoothness of the finishes, and the symmetry of the interwoven bands are indicators of quality. Ensure there are no rough edges or visible solder points that detract from the design.
Stone Security: The most important standard is how well the gemstone is secured. The prongs should hold the stone firmly without being so large as to obscure the gem or so small as to risk loosening.
Symmetry and Proportions: The interwoven pattern should be symmetrical and proportionate to the center stone.

Buying Guide

When considering a ring with a trellis setting, keep the following in mind:

Center Stone: The trellis setting is suitable for most gemstone shapes, but certain shapes, like rounds and ovals, are particularly well-showcased. Consider the size of your stone; larger stones may require a more robust trellis design.
Metal Choice: Select a metal that complements your gemstone and personal style. Platinum offers durability and a bright white luster, while various gold alloys provide warmth and color options.
Design Complexity: Decide on the level of intricacy you prefer. A simpler trellis might highlight the stone more, while a more complex design adds its own decorative flair.
Side Stones: Trellis settings often accommodate accent stones or diamond pavé along the band or within the setting itself, adding extra sparkle.
Comfort and Wearability: Ensure the setting doesn't have sharp edges that could catch on clothing or skin. The height of the setting off the finger can also affect comfort.
Certifications: For the center gemstone, look for reputable grading reports from gemological laboratories.

Price Range & Value Factors

The price of a trellis setting can vary significantly based on several factors:

Metal Type and Weight: Platinum and heavier gold settings will naturally cost more than lighter-weight or lower-karat gold settings.
Complexity of Design: More intricate and detailed trellis patterns require more labor and skill, increasing the price.
Gemstone: The size, quality, and type of the center gemstone are the primary drivers of cost.
Accent Stones: The presence and quality of any smaller diamonds or gemstones used in the setting also contribute to the overall price.
Brand and Craftsmanship: Designer pieces or rings made by highly skilled artisans will command higher prices.

Generally, the setting itself adds a moderate amount to the overall cost of a ring compared to simpler settings like a basic solitaire. The value lies in the unique aesthetic and the skilled labor involved in its creation.

Care and Maintenance

Trellis settings, like all fine jewelry, require proper care to maintain their beauty and integrity.

Regular Cleaning: Clean the ring regularly using a soft brush, mild dish soap, and warm water. This removes dirt and oils that can dull the gemstone's sparkle and collect in the intricate metalwork. Ultrasonic cleaners can be effective but should be used with caution, especially if the stone is porous or has treatments.
Professional Inspection: Have the ring inspected by a jeweler at least once a year. They can check the security of the gemstone and the integrity of the metalwork, ensuring the prongs are tight and the setting is sound.
Avoid Harsh Chemicals: Remove rings with trellis settings before swimming, cleaning with household chemicals, or applying lotions and perfumes, as these can damage the metal or affect the gemstone.
Protective Storage: Store the ring in a soft-lined jewelry box or pouch when not in use to prevent scratches and damage from other jewelry.
