Types of Synthetic Opals

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

Type 1 - Rough synthetic opals with monodisperse silica particles embedded in a polymer matrix with a non-directional pattern of play-of-color.
(Synthetic Polymer Impregnated Opal / Imitation Opal, Homogenously Crystallized Silica Particles in Polymer = HoC-Si-Pol

Type 2 - Rough synthetic opals with monodisperse silica particles embedded in a polymer matrix with a directional (columnar) pattern of play-of-color.
(Synthetic Polymer Impregnated Opal / Imitation Opal, Heterogenously Crystallized Silica Particles in Polymer = HeC-Si-Pol)

Type 3 - Cut synthetic opals with ordered monodisperse silica particles in a matrix of amorphous silica (Synthetic Opal/Created Opal, Si-Sil)

All types of synthetic opals are available in a wide variety of colours and with unique properties, which are described below.

Synthetic Impregnated Opals - Details and Description

Type 1 with a non-directional pattern of play-of-color (Hoc-Si-Pol)

Based on research and various space experiments performed under microgravity, these opals are the world's first samples of homogeneously crystallized synthetic opals, also known as colloidal or photonic crystals. This kind of synthetic impregnated 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 synthetic impregnated 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.

Synthetic impregnated opals, available colors (Color Charts):

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

A special variety of opals type 1 are the "Aurora Opals" with an impressive swirly pattern of Play-of-Color. These synthetic impregnated opals are available in three bright different colors as opals with Green, Red and Orange as dominant colors. More information: Aurora Opals

Synthetic Opals - Details and Description

Synthetic opals with the same physical and chemical properties as their naturally occurring counterparts (precious opals), but without any cracks, inclusions or host rock (matrix). These opals are inorganic opals with monodisperse silica particles embedded in an amorphous silica matrix. Grown after a modified Gilson-process the opals are high-temperature stable.
Four varieties with a beautiful and lively play-of-color are available: Black Opal, White Opal, Crystal Opal (Red or Blue) and Fire Opal.
Perfect Cut & Polish.
