Glass Pebble Gems 6-9mm Flame Polished 1/4 pound

1/4 pound of irregular lumps of flame polished glass with a nominal size of 6-9mm. Approximately 200+ pieces.



Glass Pebble Gems are our recommended alternative to regular glass gems and are much easier to grout. Our flame-polished Glass Gem Pebbles are irregular lumps that can be nested closely together than uniform dome-shaped glass gems. The size range is 6 to 9mm nominal (less than 3/8 inch). Sold by the 1/4 pound (approximately 200 pieces), which can cover an area of approximately 20+ square inches.

Why Better Than Ordinary Gems

Most glass gems are dome-shaped with shouldering sides, which results in oversized grout gaps unless you erode the grout somewhat during the grouting process. That is a lot of work and is hard to do evenly. Our Glass Gem Pebbles are irregular lumps that can be nested closely together than uniform dome-shapes, and so the grout gap is smaller. The smaller the grout-gap is, the easier to grout and the more colorful the results. The Glass Gem Pebbles are also closer in thickness to 4mm thick glass tile.

Product Variation

These are irregular lumps of glass made by flame polishing broken glass. Expect variation in size and shape. Dimensions are nominal and approximate.

Product Coverage

A 1/4-pound bag covers approximately 20+ square inches.


Glass Gem Pebbles have an average thickness that is close to the thickness of most of our glass tile. That makes it easier to use these with glass tile in the same mosaic.


These are small enough to make cutting unnecessary. Most glass is cut with a mosaic glass cutter.
