About OpalHide

Formula:
SiO2 · nH2O
Colour:
Colourless, white, yellow, red, orange, green, brown, black, blue
Lustre:
Vitreous, Waxy, Greasy, Dull
Hardness:
5½ - 6½
Specific Gravity:
1.9 - 2.3
Name:
The origin of the name is uncertain. It may be from the Sanskrit "upala", meaning "stone" or "precious stone" or from opalus, the ancient Latin name for the gem (Pliny the elder, 75-79). Pliny may have also referred to the gem as paederos, but a modern commentary by Kostov (2008) questions if that name was actually applied to the opal of modern sense.
Although it is still (2007) regarded as a valid mineral species for historical reasons, opal is not a true mineral in the accepted sense of the word as it is either composed of cristobalite and/or tridymite or composed of amorphous silica.

Opal is classified into four types:
- Opal-CT: contains cristobalite-tridymite
- Opal-C: contains cristobalite
- Opal-AG: amorphous (Amorphous-Gel) (closely packed amorphous silica spheres form a diffraction grating to create precious opal).
Opal-AN: amorphous (Amorphous-Network (found as hyalite).

Transitions between opal-AG, opal-CT and opal-C are common.

Studies at low temperature show that water molecules way be organized into ice-like structure, which includes the cubic ice modification (Eckert et al., 2015).

Optical Data of OpalHide

Type:
Isotropic

Isotropic minerals have no birefringence
Surface Relief:
Moderate

Bandfire OpalA precious opal with bands showing a play of colours.
Black OpalThe most precious kind of opal, this variety of precious opal has a dark background colour.
Blue OpalTranslucent blue opal with no play of colours. Cause of colour can be light scattering effects or occasionally microscopic admixture of chrysocolla or other minerals. (See also "Andean Opal")
Bone OpalOpal replacing fossil bone.
Boulder OpalA variety of Precious Opal found in Queensland, Australia, as cracks or coatings in and around ironstone/sandstone boulders.
Cat's Eye OpalA rare chatoyant form of opal showing a thin line of fire.

Common OpalA type of opal that doesn't show any fire.
Contra Luz OpalA precious opal where the play of colours is only visible when held up to the light.
Crystal OpalA transparent to translucent variety of Precious Opal where the colour play is visible both on the surface and in the interior.
Fire OpalA red variety of Opal.
ForcheriteA yellow to orange variety of opal, owing its colour to microscopic inclusions of orpiment and realgar.

Harlequin OpalA variety of Precious Opal in which the play of color is arranged in a vivid harlequin, diamond-shaped, or rectangular-shaped pattern.
Honey OpalAn unnecessary name for orange-brown opal.
