sapphire gemstone –
Diamonds and sapphires can be very similar to the untrained eye, though they are incredibly different gems. Both stones are very valuable and a popular choice for jewelry, including wedding bands, engagement rings and solitary pendants. They are also used to symbolize love, faith, commitment and trust. How can you tell the difference between these gems when buying or selling diamonds and sapphires? Here you can see the differences between these two gems in terms of structure, formation and price.
While this difference is imperceptible to the naked eye, diamonds and sapphires have very different structures. A diamond is made of pure carbon that crystallizes into cubes. This compact structure makes diamonds the hardest gemstone in the world with a hardness of 10 on the Moh scale. Pure carbon diamonds are absolutely colorless, although their structure may contain small amounts of other elements that produce yellow, brown, blue, pink, red, and green diamonds. Sapphires, on the other hand, have a hexagonal shape of aluminum oxide crystals. Sapphires are the second hardest gemstone in the world with a hardness of 9 on the Moh scale. Sapphires also come in many colors when other elements enter the crystal during formation.
Differences in education
These precious gems also form in very different ways. In rocks such as granite, gneiss and schist, sapphires naturally form in a hexagonal shape due to heat and pressure changes. They can be found in magmatic (cooled magma) and metamorphic (transformed) rocks. The color of sapphire comes from other minerals. Iron produces yellow or green sapphires, vanadium produces purple sapphires and titanium blue sapphires. Sapphire gemstones can also be red, though they are called rubies, not sapphires.
On the other hand, diamonds require very precise conditions to form deep in the earth at extreme pressure and relatively low temperature. There are two places on earth where diamonds can form: deep in the lithospheric mantle of the earth and in places where a meteorite hit the earth. These gems are slowly coming to the surface through volcanic pipes and diamonds that are mined today and are between 1 and 3 billion years old.
The price of these gems depends on their carat weight, cut, clarity and color, whether you buy or Sell diamonds and sapphires. In general, sapphires are generally cheaper than diamonds, as they are easier to break down on the earth's surface.
Both gems make a beautiful jewelry. The choice between the two depends on your preferences and your budget. However, if you plan to buy and sell diamonds, you must ensure that you do not receive colorless sapphires that are not usually worth so much.
