Optic Drops 12 mm – Colour Mixes

Optic Drops 12 mm – colourful glass gems for mosaic crafts

Optic Drops, also known as Mini Glass Gems, are round 12 mm glass pieces with flat backs and domed tops that add colour, shine and dimension to mosaic designs. Each colour mix combines coordinating shades, and many of the blends also contain iridescent pieces whose shimmer changes with the lighting and viewing angle. The range also includes a multicoloured mix with a lively selection of bright and soft tones.

Optic Drops are ideal for flowers, leaves, hearts, animal designs, butterfly and dragonfly wings, water and sky details, abstract patterns and eye-catching mosaic accents. They can be used to decorate plant pots, lanterns, mirrors, trays, ornaments, wall art and garden features.

Why choose an Optic Drops colour mix?

  • Ready-coordinated colour combinations
  • Glossy surfaces with iridescent finishes in many mixes
  • Flat backs for stable and easy gluing
  • Domed tops that add shine and three-dimensional texture
  • Suitable for both small details and larger colour areas
  • UV- and frost-resistant for indoor and outdoor projects

Size, pack options and approximate coverage

  • Diameter: 12 mm
  • Height: approximately 6.5 mm at the centre and 5 mm at the edge
  • 50 g: approximately 33–35 pieces, covering an area of about 7 × 7 cm
  • 200 g: approximately 132–140 pieces, covering an area of about 14 × 14 cm

The number of pieces and colour distribution may vary slightly between mixes and packs. The final coverage depends on the arrangement, grout spacing, cutting and shape of the project.

Using Optic Drops in mosaic projects

The flat backs make the pieces easy to attach with a suitable mosaic adhesive. Their rounded, domed tops sit above the finished mosaic surface and reflect light from different directions. Optic Drops can be used on their own or combined with glass mosaic tiles, mirror mosaic, natural stone and other speciality-shaped mosaic pieces.

The pieces can be cut with mosaic nippers when needed. Because of their domed shape, the cutting result may vary, so using whole pieces is often preferable whenever the design allows.

Choose the right colour mix

Choose blue and turquoise blends for water and sky designs, green mixes for leaves and nature motifs, red and pink shades for flowers and hearts, and brown or neutral colours for animals, trees and earthy patterns. Multicoloured mixes are ideal for playful, vibrant projects where a wide variety of shades is desired.
