Not in the truest sense, in that they have not occurred naturally.
Quite possibly lots of rubies,emeralds, diamonds and gold.
gold, sylver, platinum, rubies, opals, diamonds, smeralds to name a few.
Rubies are not the strongest minerals. Diamonds are the hardest minerals, ranking a 10 on the Mohs scale of mineral hardness, whereas rubies rank a 9. This means diamonds are more resistant to scratching and abrasion.
Opals, rubies, emeralds, diamonds, and sapphires are all minerals. In fact, all gems are minerals with the exception of pearls, which have a biological origin.
No, diamonds are much more expensive than rubies But it depends on the size,
Minerals are naturally occurring inorganic substances with a defined chemical composition and crystalline structure. Gems, or gemstones, are specific types of minerals that are prized for their beauty, rarity, and durability. Common examples of gem minerals include diamonds, rubies, sapphires, and emeralds, which are often cut and polished for use in jewelry. Other minerals, like quartz and topaz, can also be considered gems when they possess desirable qualities for aesthetic purposes.
Synthetic rubies are created in a lab using similar chemical components as natural rubies, but they are made under controlled conditions and typically have fewer inclusions. This often results in a more uniform color and higher clarity compared to natural rubies. Additionally, natural rubies are formed in the earth's crust over millions of years, while synthetic rubies are created in a matter of weeks.
no diamonds are
i think its diamonds!(like in minecraft)
It is true that rubies, sapphires, and emeralds are more rare than diamonds. The reason is that the elements which make up rubies, sapphires, and emeralds which give them their color are more rare in the environment than carbon which is what diamonds are made of.
Rubies are considered semi-precious due to their relative abundance compared to other precious gemstones like diamonds. While rubies are highly valued for their color and clarity, the availability of large, high-quality rubies prevents them from being classified as a precious gemstone.
They are valuable because they are rare and take a long time to process to create a good looking stone. They are classified as "gemstones".
