On the Mohs scale, Moissanite gemstones are a 9.25 on the Mohs Scale of Hardness, so they are suitable for daily wear. Diamonds are the hardest known mineral and receive a 10 on the Mohs Scale of Hardness.
Each carbon atom forms four bonds with its neighbors, explaining the overall stability and hardness of the crystal structure. Although diamond is commonly mentioned as the hardest mineral, there are minerals that are harder. Moissanite, a naturally occurring silicon-carbide, is almost as hard as diamond.
There are many gems that are more valuable than diamonds. Emeralds, sapphires, rubies, garnets, and alexandrite, just to name a few.
For centuries, humanity believed that diamonds were the hardest minerals on Earth. However, a new discovery has put this belief into doubt. Instead, this mineral, called lonsdaleite, is believed to be around 58 percent stronger than diamonds, according to NPR.
Moissanites or white sapphires are most comparable to a diamond. While there are visible differences, these gems will look the closest to a diamond while offering a more affordable price. These stones are also high on the Mohs scale of relative hardness, making them suitable for everyday wear.
Indentation strength tests have shown that wurtzite boron nitride (w-BN) is stronger than diamond, and that lonsdaleite, which is also known as hexagonal diamond due to its carbon composition and similarities to diamond, is 58% stronger than diamond.
Moissanite is an interesting gemstone, because it is both synthetic, and a diamond simulant. It is not, however, a synthetic diamond. It is a diamond simulant because it is made to look like a diamond. It is synthetic because it is made in a lab, but it is synthetic moissanite.
Moissanite is actually more brilliant than a diamond!
Moissanite's brilliance is higher than diamond's due to its higher “refractive index” (Diamond's is 2.42, whereas Moissanite's is 2.65). This is a technical term for how much a gemstone bends light.
Benitoite. This rare stone exceeds diamond's rarity as well as its "fire" or dispersion. Combined with its often sapphire-blue color, it's no wonder this is a highly sought rare gem. Gem-quality benitoite occurs only in San Benito County, California (and thus a natural choice for the California state gem).
The word diamond is derived from adámas, which is Greek for unbreakable. People's fascination with the diamond is as unbreakable as the stone itself.
Diamond – The Sheer Stunner
Possessing the highest shine of all transparent gemstones, diamond is the hardest material on earth that can only be scratched with another diamond. Its name comes from the ancient Greek adámas meaning “unbreakable”.
It is well-known since the late 20th-century that there's a form of carbon that's even harder than diamonds: carbon nanotubes. By binding carbon together into a hexagonal shape, it can hold a rigid cylindrical-shaped structure more stably than any other structure known to humankind.
These are the areas where atoms are not tightly bonded. Diamonds do not shatter when dropped, but they may chip from powerful, accidental blows. They can also break when there is pressure buildup inside the stone called 'strain. ' A small tap results in breakage for the pressure to escape.
Painite : Not just the rarest gemstone, but also the rarest mineral on earth, Painite holds the Guinness World Record for it. After its discovery in the year 1951, there existed only 2 specimens of Painite for the next many decades. By the year 2004, there were less than 2 dozens known gemstones.
Scientists have found a mineral stronger than diamond Scientists have found a mineral stronger than diamond. They say lonsdaleite could be used to fortify industrial tools like drill bits and saw blades - AND teach us about the evolution of earth.
Tanzanite is a shocking 1000 times more rare than a diamond. Discovered for the first time in 1967 and only found in the foothills of Mount Kilimanjaro, these gemstones go for about $1,500 per carat. Tanzanite has the ability to change color depending on the angle of light it is in.
One of the best diamond alternatives is white Quartz, which is often confused for a diamond. That's because white quartz gemstones are faceted to emit the most amount of light, making them appear more sparkly than they actually are.
Kimberlite is an igneous rock and a rare variant of peridotite. It is most commonly known to be the main host matrix for diamonds.
Moissanite looks so similar to diamonds that most people actually struggle to tell the difference between the two, even when placed side by side! The one telling difference is that moissanite will display slightly more rainbow sparkles than a diamond, as it has a higher refractive index.
The scientists found Q-carbon to be 60% harder than diamond-like carbon (a type of amorphous carbon with similar properties to diamond). This has led them to expect Q-carbon to be harder than diamond itself, although this still remains to be proven experimentally.
The hardest mineral on the scale, diamond, is given a hardness rating of 10. Since obsidian is rated at 5-6 on Moh's Hardness Scale, it is not stronger than a diamond; it's softer than a diamond. The diamond is one of the hardest natural substances known to scientists.
Diamonds are in fact very common, yet prices are kept high by vast stockpiling and strict supply control. Unlike diamonds however (which are incredibly hard 10/10 on the Mohs scale), opals are a relatively soft gemstone. Opals rank at a 6 on Mohs scale of mineral hardness.
