In this post, we will look at how the sapphire stone form, sapphire is a natural gemstone that is formed in the ground with no human intervention. Each stone’s composition differs based on its equivalent in other stones, but for me, Sapphire stands out for its unequalled characteristics and its distinct beautiful red hue, and it belongs to the mineral corundum, which is aluminium oxide. Most people enjoy this hue because it evokes various emotions in individuals simply by looking at it, including passion, friendship, and devotion. The presence of chromium is primarily responsible for the formation of red sapphires.)
The formation of sapphire in rocks
No one can be sure of the exact period in which the red sapphires are , but we know that the first sapphire stones that were found were formed about 150 to 200 a million years, and recent sites of sapphire give us some Evidence and pointers about where to form. Primary deposits of high-quality sapphires are only found in several specific places, and are mainly found in southern Asia, eastern Africa, the islands of Sri Lanka (Ceylon) and Madagascar.
Details of formation differ from nation to country. It may be found in abundance in igneous and metamorphic rocks. Most of the time, they occur at depths of up to 6-18 A slope in the earth’s crust.
This gemstone has several properties, including unmatched beauty, durability, purity, and rarity; these are hallmarks of stones with high pricing. We will learn about the geological processes that led to the production of this uncommon stone.
Here are the characteristics of the formation of natural sapphire as follows
The chemical formula of sapphire is aluminum oxide (Al2O3), sapphire is not one of the minerals we often hear It is the second most solid natural mineral known to man. The formation of aluminum oxide, as it is known in the mineral composition circles, from both volcanic processes located in the depths of the earth and the high degree of pressure and temperature and from the conditions of transforming processes.
As liquid lava works In the depths of the earth, the melted metals slowly cooled and turned into cold stones in the form of crystals.
The purest and most transparent forms of aluminum oxide are formed by crystallization of minerals during the transformation of rocks of volcanic origin.
It is worth noting, that this process It takes millions of years and needs only a few places in the world where there are rocky outcrops, where rare sapphire crystals are exposed in those places to weather factors.
It is normal to have forms of metallic aluminum oxide; As for the pure form of this oxide, it is transparent, opaque, that is, colorless.
As for the mineral impurities that seep into aluminum oxide like cold rocks, giving it its wonderful, distinctive colors.
The distinct colors of many gemstones are due to the presence of transition metals, for example: impurities present In the different transparent crystal retina.
to shed more light to make things clearer; This is called the crystal field or the ligand energy stability field effect. Aluminum oxide comes in several different colors, and each of these colors is valuable and expensive if it is free from penetration and is translucent or completely transparent.6465
When small amounts of Titanium and iron elements in a crystal lattice on aluminum oxide during its formation, thus forming a beautiful red ruby.
The natural crystal shape of uncut ruby is hexagonal prism and the prominent star ruby is the largest ruby in the world and is believed to come from India where it weighs
One of the characteristics of the ruby is that it is one of the rarest valuable stones and the largest in terms of size and weight ( 5 carats or more), where millions of dollars can be paid in a transparent ruby. can Ruby red stones with inclusions or weaker colors are treasured by heat treatment, which will help to remove the impurities that darken the stone and deepen its color.Heat-treated stones differ from their natural counterparts in that heat-treated stones are not Desirable in contrast to naturally translucent stones or darker colored stones.
It is worth mentioning that rubies may be discovered in rock and marble mines, particularly in Myanmar (Burma), Vietnam, Afghanistan, Pakistan, and Nepal.
