What is a opals grain size?
Opal's grain size refers to the size of the silica spheres that make up the gemstone. Larger grain sizes can enhance the play of colors in opals, while smaller grain sizes may result in a more uniform color appearance. Grains in opal are typically between 150 and 300 nanometers in size.
Is opal valuable?
Ther is no set answer to this question. Each opal is unique and has its own value. From colorless opal to the most prized fire opal it depends on the size and color.

What sedimetary rock has the smallest grain size?
Shale is a sedimentary rock that typically has the smallest grain size due to its fine-grained and compacted nature.
What is grain according to geologists?
Grain refers to particle or crystal size in rock.
What are 3 characteristics of a rock?
1.Grain Size 2.Grain Shape 3.Grain Pattern
What else does rock texture include besides grain size and arrangement?
Grain shape.
Which features tells you how large the grains of a sedimentary rock are?
The size of the grains in a sedimentary rock can be determined by examining the texture of the rock. Coarser grains indicate a larger grain size, while finer grains indicate a smaller grain size. Other features that can provide clues to grain size include the sorting (uniformity of grain sizes) and rounding of the grains.
Wind mostly erodes pieces of rock that are what size?
the size of a sand grain or smaller
How does texture affect grain size in rock?
It doesn't. The grain size effects the texture. If a rock has a small grain size, it will have a smooth texture. If the grain size is large, such as pebbles, the texture will be rough. For example, siltstone is one of the smoothest rocks because it contains silt particles, which are .0004cm to .006cm. Conglomerate though contains various particles including cobbles and boulders, which are from 10cm to 100cm.
What are the size shape and positions of the grain that makes up a rock?
These characteristics determine a rock's texture.
What are the grains of rock?
Grains: Grains that are not crystals in rock do not have flat shiny faces. They are rounded, like grain of sand, or jagged, like a piece of broken rock. Grain Size: Grain size in rocks can mean the size of crystal grains or of fragments: Coarse Grained: most of the rock is made of grains as largeas rice, or larger.
