In the realm of fine jewelry, the technique of flush setting stones is a testament to quality and craftsmanship. This method involves setting a gemstone into a drilled hole so that it sits 'flush' with the surface of the metal, creating a sleek and sophisticated finish. It's a technique that requires precision and skill, as the stone must be set securely without any prongs or claws, ensuring it blends seamlessly with the piece's design. Flush set stones are not only aesthetically pleasing but also practical, providing a smooth surface less likely to snag on clothing.

The process of flush setting begins with selecting the right stones and metals. Your choice in stones is crucial, as they must be hard enough to withstand the pressure of setting. Diamonds, sapphires, and rubies are commonly used due to their durability. The metal surrounding the stone should be malleable yet strong enough to hold the gem in place without bending or warping. Gold, platinum, and sterling silver are popular choices for their workability and strength.

Achieving a perfect flush set is a delicate balance of art and technique. It involves careful drilling, accurate measuring, and precise stone setting. While the end result is a clean and modern look, the process is intricate and detailed. Mastery of flush setting embodies the epitome of fine jewelry making, where the beauty of a gemstone is enhanced by the metal it's set in, without the distraction of additional settings. It's a skill that distinguishes the exceptional from the commonplace in the world of jewelry design.

Understanding Flush Settings


When you explore the varied techniques of stone setting in jewelry, flush settings stand out for their seamless appearance and the protection they offer to stones.

Definition and Benefits

Flush set refers to a stone setting technique where the stone is set into a drilled hole within the metal, allowing the girdle of the stone to sit flush with the surface. Here's a succinct breakdown:

  • Protection: This style provides excellent protection for the stone's girdle, minimizing chips and scratches.
  • Sleek Appearance: Offers a sleek, unfussy look that lends itself to both modern and minimalist designs.
  • Sparkle Retention: Despite the metal surrounding the stone, it retains the sparkle as the top of the stone remains exposed.

Comparison With Other Settings

In comparison to other settings, flush setting holds a unique place:

  • Prong Setting:
    • Prongs hold the stone above the metal which often allows more light into the stone, enhancing sparkle.
    • Less metal means less protection for the stone's edges.
  • Bezel Setting:
    • Surrounds the stone with a rim of metal, which could diminish the stone's brilliance but offers more protection than prongs.
    • Can appear bulkier than the flush style.
  • Pavé Setting:
    • Features multiple stones set closely together, held by small beads of metal.
    • Though it provides an overall sparkle, individual stones are not as protected as in a flush setting.

When you choose a flush setting, you're opting for a style that balances the stone's protection with a subtle, contemporary appearance, making it an ideal choice for an active lifestyle or a preference for understated elegance.

Materials and Tools

When flush setting stones, the materials and tools you use will directly affect the quality and appearance of your finished piece. It's crucial to select appropriate metals and stones, and to utilize precise tools for setting.

Selection of Metals

For the base of your stone setting, you'll need to choose a precious metal such as gold, silver, or platinum as they offer the best combination of durability and workability. Copper is also an option, but it's typically used for practice due to its softer nature. When preparing your metal, make sure it's properly annealed for ease of setting.

Types of Stones

The stones you select should match the scale and style of the jewelry piece. Opt for gems that are hard enough to withstand the setting process without cracking. Ensure that the girdle of the stone - the outer edge where the top meets the sides - is even and flat, as this will sit flush against the metal.

Essential Setting Tools

Your toolset should include:

  • Drill and drill bits: to create initial holes in the metal for the stones.
  • Burs: specifically, a setting bur to refine the hole to match the stone's girdle, and a ball bur to create a seat for the stone.
  • Flex shaft: for precision when working with drill bits and burs.
  • Burnisher: to smooth the metal around the stone and ensure a snug fit.
  • Graver: to carefully cut metal and create a clean edge around the stone.
  • Hammer and vise: for tasks that require controlled force.
  • Loupe: to closely inspect the setting for any irregularities or adjustments needed.
  • Soldering equipment: for tasks like attaching prongs or other components to your piece before setting the stone.

Assemble these tools in advance to ensure a seamless stone-setting process. Always work with a steady hand and keen eye to achieve professional results.

Preparation and Design

Before you begin flush setting stones into jewelry, it's crucial to focus on meticulous preparation and a precise design process to ensure that your stones are securely set and the metal surface is flawlessly finished.

Stone Fitting

Fit is paramount in flush mount setting; each stone must sit level with the metal's surface. Begin by selecting a burr that corresponds to the size of your stone—this should be slightly smaller than the stone diameter for rubies or diamonds. For faceted stones, ensure the burr creates a seat that matches the stone's pavilion angle, allowing it to sit flush.

Drilling the Metal

After marking your setting points, drill a pilot hole with a small drill bit before enlarging it with a burr to accommodate the stone. This process is critical for round stones and should be practiced on scrap metal to hone your technique. Aim for a snug fit; the stone should not drop into the hole without slight pressure.

Ensuring Cleanliness

To achieve a clean set, the hole and surrounding metal must be free of debris. Use a soft brush to clean out any metal filings and inspect the seat with a loupe before setting. The cleanliness in your jewelry making process not only affects the final appearance but also the security of the stone in its halo or chosen setting.

Creating the Seat for Stone

First, determine the right position for your stone and mark the metal surface. Using a ball burr, create a seat that corresponds to the size and shape of the girdle of the stone. The seat should be just shallow enough to hold the stone's girdle slightly below the metal surface, ensuring a flush setting.

Inserting the Stone

Place the stone into the seat carefully. Use a bezel pusher to gently press the edges around the stone, testing for any movement. Your stone must fit snugly into the seat with no wobbling, indicating a secure setting.

Burnishing Techniques

To finish the flush setting, employ burnishing techniques to smooth and fold the metal around the girdle of the stone. Use a burnisher to rub the metal, creating a bright, smooth finish that holds the stone firmly in place. Use steady, even pressure to avoid slipping and scratching the surface.

Finishing Touches

In the final stage of flush setting stones, attention to detail in polishing and inspection ensures the highlight of your craftsmanship and the enhancement of the stone's quality. This process adds the necessary lustre to the gold and longevity to the piece.

Polishing the Set Stone

After securely setting your gemstone, polishing is essential. Use a polishing cloth to gently rub the gold surface around the gemstone, ensuring that you do not disrupt the stone's placement. Consider guidance from renowned jewelers like Charles Lewton-Brain and Alan Revere—who emphasize a light touch and the right polishing agents to both bring out a high shine and maintain the durability of the gold. For the best results, focus on the areas immediately surrounding the stone to create a harmonious transition from the glow of the polished metal to the brilliance of the gemstone at the center.

Final Inspection and Cleaning

Your final inspection should be thorough, examining the setting for any imperfections or residue. Employ a loupe to scrutinize the craftsmanship—the stone should be snug against the gold, without any movement. Clean your piece using a soft brush and mild cleaning solution to remove lingering polishing compounds. Rinse with lukewarm water and dry with a lint-free cloth, which guarantees that the inherent quality and durability of the materials—gold and gemstones—are unblemished, reflecting the finesse of your work.
