Sapphire is one of the hardest materials and can only be scratched by materials that are harder than itself, such as diamonds or other sapphires. Common materials like glass, metal, and plastic are not hard enough to scratch sapphire.
a blue diamond! :P GEMUSE!! maybe a saphire.
A watch with sapphire glass has a transparent cover made from synthetic sapphire crystal. Sapphire glass is highly scratch-resistant, making it more durable and less prone to scratches than other types of watch crystals like mineral glass or acrylic. This results in a clearer and more scratch-free surface for the watch face.
A scratch test can compare the hardness, wear resistance, and surface finish of materials. By observing the depth and width of the scratch made on different materials, one can infer their relative hardness and how well they resist abrasion.
Nickel can be scratched by materials that are harder than it, such as iron and steel. Additionally, abrasive materials like sandpaper or ceramic can also scratch nickel surfaces.
A hard material is not easily scratched, as its strong structure makes it resistant to scratches. Examples of hard materials include diamond and sapphire, which are known for their durability and scratch resistance.
Diamond is one of the hardest materials and can only be scratched by another diamond. Other materials that are difficult to scratch include sapphire and tungsten carbide.
Diamond is one of the hardest materials and is difficult to scratch due to its strong covalent bonding structure. Other materials such as tungsten carbide, sapphire, and ceramic are also known for their high scratch resistance.

Scratch resistance. It refers to a material's ability to withstand scratches and maintain its appearance over time. Materials such as sapphire, ceramic, and some special coatings are known for their high scratch resistance.
Diamond will scratch everything, including diamond.
The crystal of a watch is the transparent cover that protects the dial and hands. It is typically made from materials like mineral glass, sapphire crystal, or acrylic. The quality of the crystal can affect the scratch resistance and overall durability of the watch.

The main compound in ruby and sapphire is corundum. It is made of transparent materials in both ruby and sapphire.
A copper penny can scratch materials with a Mohs hardness of 2.5 or lower, such as gypsum, talc, and some plastics. It will not scratch harder materials like glass, steel, or most ceramics.
Carbon fiber is known for its high strength and durability, but it can still scratch easily compared to some other materials.
SGP on a watch typically refers to "Sapphire Glass, Gold Plating," indicating that the watch features a sapphire crystal for scratch resistance and has gold plating on its case or components. This designation highlights the watch's durability and aesthetic appeal. It's often used by manufacturers to signify quality materials used in the watch's construction.
