Minecraft: An ancient fireproof alloy made from gold and netherite scraps, which are smelted from ancient debris found in the game's hellish Nether dimension. When combined with diamond equipment, the metal creates the game's strongest weapons and armor. [53] [54] Nth Metal DC Comics: Fictional alloy; described as a heavy isotope, 676 Fe. [55]
The measurement of sales of popular music starts high relative to the wedding anniversary scale, concentrating on gold and platinum (see gold album).Likewise, credit card companies usually have a "gold card" and a "platinum card" (many formerly had a "silver card" then followed by a "gold card", but due to similarity in appearance between silver and platinum these were often discontinued with ...
The simulants imitate the look and color of the real stone but possess neither their chemical nor physical characteristics. In general, all are less hard than diamond. Moissanite actually has a higher refractive index than diamond, and when presented beside an equivalently sized and cut diamond will show more "fire".
As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium. It is followed by caesium, iridium and palladium by mass and iridium, gold and platinum by volume. Carbon in the form of diamond can be more expensive than rhodium. Per-kilogram prices of some synthetic radioisotopes range to trillions of dollars.
Amber is fossilized tree resin. Examples of it have been appreciated for its color and natural beauty since the Neolithic times, [1] and worked as a gemstone since antiquity. [2] Amber is used in jewelry and as a healing agent in folk medicine. There are five classes of amber, defined on the basis of their chemical constituents.
A diamond simulant, diamond imitation or imitation diamond is an object or material with gemological characteristics similar to those of a diamond. Simulants are distinct from synthetic diamonds , which are actual diamonds exhibiting the same material properties as natural diamonds.
Glasses containing a high proportion of alkali or alkaline earth elements are more susceptible to corrosion than other glass compositions. [ 67 ] [ 68 ] The density of glass varies with chemical composition with values ranging from 2.2 grams per cubic centimetre (2,200 kg/m 3 ) for fused silica to 7.2 grams per cubic centimetre (7,200 kg/m 3 ...
After color follows clarity: similar to diamonds, a clear stone will command a premium, but a ruby without any needle-like rutile inclusions may indicate that the stone has been treated. Ruby is the traditional birthstone for July and is usually red/pinker than garnet , although some rhodolite garnets have a similar pinkish hue to most rubies.
