The darlovely Materials Guide: Size, History, & My Personal Favorites

Every jewelry designer has a "signature" palette of materials. For me, the beauty of a piece lies in the precision of the beads and the stories they tell. Here is a look at the six beads I use most often, why I love them, and the history behind them.

1. Bicone Crystals

This is one of my earliest favorite beads. I love the symmetry and uniform shape, which results in beautiful flower shapes being created. In my earlier designs, these were a "must-have."

• Size: Most commonly used in 3mm, 4mm, and 6mm.

• The History: Popularized in the mid-20th century by Swarovski, the bicone (two cones joined at the base) was designed to maximize light refraction. In the early 2000s, it became the "gold standard" for adding luxury and sparkle to beadwork.

2. SuperDuo® Beads

As one of the earliest 2-hole beads, it opened a whole new world in beading. More intricate designs can be created because of the interesting ways you can bead through the two holes.

• Size: 2.5mm x 5mm with two 0.8mm holes.

• The History: Introduced around 2010–2011 by Matubo, the SuperDuo revolutionized the industry. Unlike earlier "Twin" beads, these are pressed glass, meaning every bead is identical. This precision allows for the complex, interlocking patterns we see today.

3. ZoliDuo® Beads

One of my favorite 2-hole beads! I love the unique curve this bead presents.

Tip: When I first used this bead, I had difficulty identifying the Left and Right versions until I noticed that the Left version is actually shaped like a comma (,). I hope you find this tip useful!

• Size: 5mm x 8mm with two parallel 0.7mm holes.

• The History: A 2017 innovation from the Czech Republic, these were the first beads manufactured in "Left" and "Right" versions to allow for perfect symmetry in paisley or teardrop designs.

4. GemDuo & DiamonDuo® Beads

These two beads are the same size and similarly shaped; I often use them interchangeably in my designs.

• Size: Approximately 5mm x 8mm.

• The History: The DiamonDuo paved the way, followed by the GemDuo in 2016. The GemDuo is known for its lower profile and sharper edges, which allow the beads to "nestle" together with almost no gaps, creating a mosaic-like surface.

5. Silky Beads

I love the way these beads form a tile-like mosaic. The way the diagonal holes are positioned creates very interesting motifs.

• Size: 6mm x 6mm (square) with two diagonal holes.

• The History: Introduced in 2014, these are famous for their "silky" texture and 3D diamond-patterned top. The diagonal holes allow for a "tile" effect that is very different from traditional square beads.

6. StormDuo® Beads

Finally, the StormDuo! It has a wonderful swirling curve. I often use the StormDuo when I want to create a design that feels more dynamic. Because of its tapered ends, it sits beautifully next to round beads or bicone, creating a "framed" effect that you just can't get with standard rectangular or oval beads

Take Note: Just like with ZoliDuos, extra care is needed when threading these. The orientation of the bead will affect the design—if it's flipped, the pattern won't sit right!

• Size: 7mm x 3mm with two 0.8mm holes.

• The History: Arriving in 2016, the "S" shape was designed to bring a "swirling" motion to weaving, allowing beads to fan out into circular or sunburst patterns.

Why I Choose These

I select these beads not just for their beauty, but because their history is rooted in Czech glass craftsmanship. Their consistent sizing means that when you follow one of my patterns, your finished piece will be just as structurally sound and symmetrical as the original.
