small patterned art-glass gems 10-12mm 2-ounces (~50+ pieces)

SKU: millefiori-translucent-gems Category:


Millefiori Gems 10mm-12mm (3/8 inch to 1/2 inch) are the rounded gems used to make millefiori beads, but they do not have beading holes and are used for mosaic art. The sides are rounded so the pieces are ovoid bead-shapes instead of being cylinders with straight edges like standard millefiori. The gems are sold in 2-ounce units (approximately 50+ pieces) and are much cheaper than traditional Italian millefiori.

Note that the designs are fairly uniform, and there aren’t many different designs, usually only three or four designs per color. Don’t expect an assortment of many different designs.

What Is Millefiori?

Millefiori is a traditional form of art glass that is disk-shaped with different multicolored patterns and is used in glass fusing, jewelry, and mosaic art.

Product Coverage

This is a problematic question because the millefiori was intended to be used as an accent instead of as area coverage, and the piece size can vary. That being said, one 2-ounce bag should cover roughly 5 or 6 square inches, but that will depend somewhat on how efficiently you nest the pieces.


The thickness is about 1/8 inch and is the nominal thickness of most of the glass mosaic tile we sell, so it should be fairly easy to incorporated these into your art.

Cutting Millefiori Gems

Millefiori Gems can be cut using the Mosaic Glass Cutter we sell, but these are small enough to use without cutting.

Using Millefiori Gems In Mosaic Art

Millefiori Gems are more consistent in thickness than most millefiori assortments. They can be used in thinset mortar for mosaic art in outdoor and wet projects. For dry, indoor projects, you can attach it to backers with a high-quality white PVA adhesive like the Weldbond we sell. A pair of tweezers are indispensable for positioning the tiny pieces like these and keeping your fingertips cleaner of glues and cements.
