Impregnated Synthetic Opals with a brilliant Play-of-Color

Multicolored opals with a Directional Pattern of Play-of-Color. Opals Type 2 / Coarse Crystalline Opals
Our Impregnated Synthetic Opals - Higher Toughness, Bigger Sizes, Brilliant Colors
  • Due to a higher silica content of 82-85% and thus lower content of resin (15-18%) the synthetic opals display a higher strength, toughness and better chemical and abrasion resistance compared to similar opals

  • The big size of opal slabs with diameters of 20 cm does not only allow the production of large objects, but also enables a more efficient processing with a high yield
Synthetic Opal - Colloidal Crystals with Fire

    The preparation of our synthetic opal takes place in 4 main steps:

  • Step 1: Preparation of monodisperse silica particles
    Our advanced technology allows us to prepare highly monodisperse spherical silica particles with an extremely narrow size distribution and sizes comparable to the wavelength of visible light. These particles are an essential prerequisite in order to obtain a synthetic opal with brillant colors.

  • Step 2: Self-assembly into a crystalline colloidal array
    In this step colloidal crystals are formed by gravitational sedimentation of monodisperse silica particles. This process, also known as heterogeneous crystallization, leads to a close packed arrangement of silica particles with angle dependent bragg diffraction colors, the well-known "play-of-color" or "fire" of synthetic opals.

  • Step 3: Drying
    After controlled drying, a multicrystalline porous synthetic opal is obtained, which is comparable to natural occurring hydrophane opals.

  • Step 4: Impregnation
    The porous synthetic opal is now impregnated with resin to achieve high toughness and strength. With carefully selected resins and monodisperse silica particles in certain sizes, we are now able to offer synthetic opals in high quality with different body colors and a play-of-color in red, orange or green.
Advantages of Synthetic Opal

    Synthetic opal is a great and affordable substitute for natural opal with some advantages:

  • No Cracking or Crazing
    In contrast to natural opals synthetic opal does not contain water and cracking due to dehydration will not occur.

  • No Special Care Required
    Even in the case that the synthetic opal is damaged or lost the opal can be replaced by a stone of the same shape, size, body color and fire.

  • Calibrated Sizes
    In contrast to natural opal synthetic opals can be cut and carved into different shapes of the same size.

  • Synthetic Opal - No Treatments
    Natural gemstones are often treated to increase their value, but with a synthetic opal you know what you get - just a colorful stone

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 a 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. The impregnated opals are available with a multicolored pattern in a variety of colors, sizes and weights, ranging from 50 - 800 grams.
