Lab Created Opals and Impregnated Synthetic Opal - Details and Description

Coarse and Fine Crystalline Opals with a Non-Directional Pattern of Play-of-Color

Based on various space experiments performed under microgravity, these lab created opals are the world's first samples of homogeneously crystallized opals, also known as colloidal or photonic crystals. This type of man-made opal shows an intense play-of-color with an irregular, non-directional and polygonal pattern like natural opals, but without any cracks, inclusions or host rock (matrix).

These lab opals don't show a columnar pattern typical for opals grown by sedimentation. Thus, an orientation of the opals prior cutting is not necessary anymore.

Furthermore, in contrast to conventional impregnated synthetic opal the new preparation method by homogeneous crystallization allows a significant lower silica content. This makes the processing of the coarse and fine crystalline opals much easier and both opal types can be drilled, carved, sliced and cut by standard carbide tools.

The non-directional and coarse-grained pattern with big crystallites make the lab created opals an ideal material to cut colorful beads, teardrops and cabochons for jewelry. But of course, the opals can be used also as inlays for musical instruments and furniture, as mosaic tiles or handle material for knives, brushes and other exclusive objects. Furthermore, the size of the opals allows carving of big objects and sulptures, solid opal rings and bangles.

A special variety of our lab created opals are fine crystalline "Aurora Opals" with an impressive swirly or flame-like pattern of play-of-color. These man-made opals are available in three bright different colors as opals with Green, Blue and Orange as dominant colors. More information: Aurora Opals

We offer also a new type of synthetic opal with a columnar pattern. Our synthetic opals are available as white, blue, black and orange fire opals with a play-of-color in orange, red and green. Due to a higher silica content (= lower content of resin) the synthetic opals display a higher strength, toughness and better chemical and abrasion resistance compared to similar opals. Additionally, in contrast to the irregular synthetic opal fragments offered elsewhere, the consistent thickness of our synthetic opal slabs allows a more efficient processing (higher yield).

All our lab created opals are offered only as rough opals, either as blocks (coarse crystalline and fine crystalline opals) or as fragments/slabs (synthetic opal)
