Chainmail jewelry has a timeless appeal, blending ancient techniques with modern creativity. Whether you’re crafting intricate bracelets, statement necklaces, or dramatic earrings, choosing the right weave—and the right jump rings—is essential. But not all chainmail weaves are created equal, and each pattern requires specific ring sizes and gauges to function and drape correctly.

In this guide, we’ll explore the top five most popular chainmail weaves, what makes each unique, and exactly what type of jump rings you need to bring them to life.

1. European 4-in-1: The Classic Starter Weave

Overview:
This is one of the oldest and most traditional chainmail weaves, originally used for armor in medieval Europe. Today, it’s a favorite for jewelry due to its fluid, fabric-like drape.

Structure:
Each ring passes through four others in a grid-like pattern, creating a tight but flexible sheet.

Best For:
Bracelets, chokers, cuffs, or wide bands.

Recommended Jump Rings:

  • Material: Aluminum (for lightness) or stainless steel (for strength)

  • Gauge: 18 AWG (1.0 mm)

  • Inner Diameter (ID): 1/4″ (6.35 mm)

  • Aspect Ratio (AR): ~4.0–4.2 (ideal for movement and stability)

Pro Tip: If your rings are too small, the weave becomes stiff. Too large, and it collapses. Stick close to the recommended aspect ratio.

2. Byzantine: The Most Popular Chainmaille Design

Overview:
Byzantine is a compact, intricate-looking weave that’s deceptively easy to learn. Its elegant, symmetrical pattern makes it a favorite among jewelry makers.

Structure:
A repeating pattern of two connected rings surrounded by a series of folded rings, forming boxy, decorative units.

Best For:
Chains, bracelets, earrings, and pendant bases.

Recommended Jump Rings:

  • Material: Sterling silver, niobium, or anodized aluminum for color

  • Gauge: 20 AWG (0.8 mm) or 18 AWG (1.0 mm)

  • Inner Diameter (ID): 3.5–4.0 mm (for 20 gauge) or 5.0–5.5 mm (for 18 gauge)

  • Aspect Ratio (AR): ~3.5–4.0

Pro Tip: If you’re just starting, use brightly colored aluminum rings to better visualize the folding and pattern.

3. Box Chain: The Geometric Beauty

Overview:
The Box Chain (also called Inca Puno) is closely related to Byzantine but features a more geometric, block-like appearance without the folding structure.

Structure:
Four-ring segments are connected in a square layout, forming a cube-like chain.

Best For:
Unisex chain necklaces, bracelet cords, and minimalist designs.

Recommended Jump Rings:

  • Material: Brass or stainless steel for clean lines and strength

  • Gauge: 18 AWG (1.0 mm)

  • Inner Diameter (ID): 3/16″ (4.76 mm)

  • Aspect Ratio (AR): ~3.8–4.0

Pro Tip: Box Chain is best when the rings are tight enough to maintain structure but loose enough for smooth flexibility.

4. Full Persian 6-in-1: The Bold Statement Chain

Overview:
Full Persian 6-in-1 is a dense, spiraling weave that results in a rope-like appearance. It’s visually striking and very strong.

Structure:
Each ring connects to six others, forming a tightly interlocked spiral chain.

Best For:
Heavy bracelets, dog tags, keychains, and necklaces with substance.

Recommended Jump Rings:

  • Material: Stainless steel or titanium for strength

  • Gauge: 16 AWG (1.2 mm)

  • Inner Diameter (ID): 1/4″ (6.35 mm)

  • Aspect Ratio (AR): ~4.0–4.2

Pro Tip: Because of its complexity, Full Persian is best for intermediate-to-advanced chainmaillers. Make sure your rings are tough enough to handle the tension without deforming.

5. Helm Chain: A Beautiful Blend of Round and Flat

Overview:
Helm Chain (a.k.a. Parallel Chain) is a layered weave that uses both small and large rings, giving a dimensional and elegant appearance.

Structure:
Larger rings are spaced apart and connected by smaller rings in the middle, creating a lacy, decorative effect.

Best For:
Delicate necklaces, earrings, and formal designs.

Recommended Jump Rings:

  • Material: Bright aluminum or colored anodized aluminum

  • Gauge: 18 AWG (1.0 mm)

  • Large Ring ID: 6.5–7.0 mm

  • Small Ring ID: 3.5–4.0 mm

  • Aspect Ratio (AR): Large rings should be AR 5.0+, small rings AR ~3.5

Pro Tip: Use contrasting colors between large and small rings for dramatic visual impact.

Understanding Aspect Ratio (AR): Why It Matters

The aspect ratio is the relationship between a jump ring’s inner diameter and the thickness of its wire (AR = ID ÷ wire diameter). It determines how well a weave will hold together and move. If the AR is too low, the weave becomes stiff or won’t fit. Too high, and it falls apart.

Many chainmail suppliers include AR in their listings, but if you’re making your own rings, calculate it before starting your project.

Materials Matter: Choose Wisely

While you can experiment with many metals, here’s a quick rundown for chainmail:

  • Aluminum: Lightweight, colorful, beginner-friendly

  • Stainless Steel: Strong and durable but harder to bend

  • Sterling Silver: Elegant and soft; great for upscale designs

  • Brass/Bronze: Warm tones with moderate strength

  • Titanium/Niobium: Hypoallergenic and strong, great for sensitive skin

Use saw-cut jump rings for better closures. Machine-cut rings often leave gaps or jagged ends that weaken your weave.

Final Thoughts

Chainmail jewelry is both a science and an art. The weave you choose should suit your style, but the chainmail jump rings rings you use must suit the weave. Understanding the right size, gauge, material, and aspect ratio ensures that your designs won’t just look stunning—they’ll be strong, wearable, and long-lasting.

Whether you’re weaving your first Byzantine bracelet or mastering the Full Persian, the right jump rings are your most powerful tool. Happy weaving!
