Sapphire is a form of the mineral corundum.
Sapphire is a form of the mineral corundum.
No, sapphire is not a silicate. Sapphire is a variety of the mineral corundum, which is composed of aluminum oxide (Al2O3). Silicates are minerals that contain silicon and oxygen as their main components, such as quartz and feldspar. Sapphire belongs to the oxide mineral group, not the silicate group.
Sapphire is a gem-quality variant of the mineral corundum.
A pink sapphire is made when the main sapphire minerals have additional chromium added to the mix. This gives it a pink or red hue. A red-hued sapphire is also known as a ruby.

Rock minerals form from lava, magma or solutions.
Ruby,Emerld,Topaz,Dimond and Sapphire are most expensive
vein minerals form between faults.
Most minerals form crystals.
Most minerals form crystals.
Several minerals form in slow cooling magma. Some of those minerals are quartz, plagioclase feldspar, and potassium feldspar. These are the same minerals that are found in granite.
No, minerals cannot form by decrystallization. Decrystallization refers to the breakdown of minerals into their constituent components, not the formation of new minerals. Minerals are usually formed through solidification from a molten state, precipitation from a solution, or chemical alteration of preexisting minerals.
