Briolette Setting Techniques: Three Reliable Methods for Jewelry Making

Briolette ​gemstones can create some of the most elegant and eye-catching jewelry designs. Their elongated, faceted teardrop shape allows light to move beautifully through the stone, making them especially attractive for earrings, pendants, and necklaces.

Yet setting a briolette can present challenges that aren't normally encountered with traditionally cut gemstones.

Historically, jewelers have had to deal with limited access to gemstone drilling services, poorly fitting caps, inadequate surface preparation, and adhesives that weren't suitable for the job. These difficulties have sometimes discouraged designers from working with briolettes altogether.

Fortunately, there are several practical ways to mount them securely while preserving the beauty of the gemstone.

Here are three commonly used methods for mounting briolettes, each offering its own advantages.

1. Vertical Blind-Hole Drilling and Pin-Cap Setting

One of the cleanest approaches is to drill a small vertical blind hole into the top of the briolette, typically about 2–4 mm deep. A pin-cap can then be inserted into the hole and secured with an appropriate jewelry adhesive.

Because the hole does not pass completely through the gemstone, the setting remains relatively discreet.

One of the biggest advantages of this technique is its appearance. Compared with a larger conical cap, a pin-cap creates a lighter and more delicate finished piece while allowing more of the gemstone to remain visible.

This technique can be particularly useful for smaller briolettes that may be difficult to fit with conventional caps. A standardized pin-cap design may also accommodate a variety of briolette sizes, simplifying the jewelry-making process.

Best suited for: Smaller briolettes, minimalist jewelry designs, and pieces where maximum gemstone visibility is desired.

2. Horizontal Cross-Drilling

Another popular approach is to cross-drill the upper portion of the briolette horizontally.

A wire, pin, or similar jewelry component can then pass through the opening, allowing the gemstone to hang and move freely.

The obvious advantage is that no adhesive is required. For jewelers who prefer purely mechanical connections, cross-drilling provides an attractive alternative.

The resulting movement can also become part of the design. A freely suspended briolette can catch and reflect light as the wearer moves, making this technique particularly appealing for earrings and dangling pendants.

The trade-off is strength. Drilling completely through the gemstone creates a potential weak point, so the technique may not provide the same durability as some other mounting methods.

Best suited for: Medium and larger briolettes, dangling jewelry designs, and applications where a free-moving gemstone is desirable.

3. Conical Cap with Epoxy Adhesive

A third solution is to mount the briolette inside a conical metal cap using an appropriate epoxy adhesive.

Unlike drilled settings, this technique does not require creating a hole in the gemstone. Instead, the cap is bonded directly to the upper portion of the briolette.

Surface preparation is especially important.

For a strong bond, the contact area at the tip of the briolette can be carefully air-abraded to create a suitable bonding surface. Typically, approximately 3–8 mm of the briolette's tip is prepared, depending on the size and shape of the stone and cap.

The larger contact area created by a properly fitted conical cap can provide a strong bond while also introducing more precious metal into the visual design.

This can produce a more substantial and traditional jewelry appearance than the smaller pin-cap method.

Best suited for: Most medium and large briolettes, designs featuring visible precious metal, and applications where drilling the gemstone is undesirable.

Which Briolette Setting Method Should You Choose?

There isn't one mounting method that is ideal for every briolette. The best choice depends on the gemstone's size, material, shape, durability, and intended jewelry design.

For a delicate and minimalist appearance, the vertical blind-hole and pin-cap method can be an excellent solution. If movement and an adhesive-free connection are priorities, horizontal cross-drilling may be preferable. For a more substantial setting with a larger bonding surface, a properly prepared conical cap and epoxy system can provide an attractive alternative.

Whichever method is chosen, briolettes require careful handling. Gemstone materials vary considerably in hardness, cleavage, brittleness, and sensitivity to heat or mechanical stress. Drilling and surface preparation should therefore be performed with tools and techniques appropriate for the particular gemstone.

The Beauty of Briolette​-Cut Gemstones

Part of the appeal of briolettes is their simplicity. Unlike conventional faceted stones that are usually secured inside prongs or bezels, a briolette​ can become the centerpiece of a design with very little metal surrounding it.

That allows the gemstone's colour, transparency, faceting, and natural movement to take centre stage.

Whether you're a jewelry maker looking for an unusual gemstone or a collector interested in distinctive cuts, briolettes offer an elegant way to showcase the character of a beautiful stone.
