Types of Lab Created Opals

We offer the whole range of lab created opals and impregnated synthetic opals in different types:

Type 1
Coarse and fine crystalline varieties of rough synthetic opals with monodisperse silica particles embedded in a polymer matrix with a non-directional pattern of play-of-color.
(Lab Created Opal / Imitation Opal)

Color Charts:
Opals with Red Play-of-Color
Opals with Green Play-of-Color

Type 2
Coarse crystalline rough synthetic opals with monodisperse silica particles embedded in a polymer matrix with a directional (columnar) pattern of play-of-color.

Lab Created Opals - Details and Description

Coarse and Fine Crystalline Opals with a Non-Directional Pattern of Play-of-Color (Type 1)

Based on research and various space experiments performed under microgravity, these opals are the world's first samples of homogeneously crystallized opals, also known as colloidal or photonic crystals. This kind of opals 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). The opals are composed of self-organized and ordered monodisperse silica particles embedded in an organic polymer matrix and due to the lack of water in its chemical composition they are not prone to cracking or crazing. Seven varieties of the lab created opals in different body tones and with a beautiful, sparkling and vivid play-of-color are available: White Opal, Black Opal, Yellow Opal, Orange Opal, Blue, Purple and Green Opal.

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

Furthermore, in contrast to conventional impregnated synthetic opals 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 types can be drilled, carved, sliced and cut by standard carbide tools.

The non-directional and coarse-grained pattern with big crystallites of 2-3 mm make the synthetic impregnated 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. Due to the flexibility of the opals in thin sheets also curved surfaces can be decorated. Furthermore, the size of the opals allows carving of big objects and sulptures, solid opal rings and bangles.

Impregnated Synthetic Opals - Details and Description

Coarse Crystalline Opals with a directional pattern of play-of-color (Type 2)

These impregnated synthetic opals show an intense play-of-color with an directional (columnar) pattern without any cracks, inclusions or host rock (matrix). The opals are composed of self-organized and close-packed monodisperse silica particles embedded in an organic polymer matrix and due to the lack of water in its chemical composition they are not prone to cracking or crazing. All impregnated synthetic opals are available with a multicolored pattern in weights ranging from 50 - 800 grams as black opals, white opals, blue opals and fire opals
