Diamonds come in a large range of colors that are hard to distinguish for the “average” layman. You have to have the right light to look at the diamonds and a set of color graded stones for comparison.
Then there is clarity. You need a 10X powered loop to examine and look for flaws etc.
Then there is the cut or make which is different from the shape (rounds, emerald, oval, etc.). The cut or make must be very well and precisely done to extract the maximum amount of sparkle and light etc. It takes great skill and a lot of time to cut and polish a diamond.
One of the few absolutes about diamonds is the carat weight. You need a very fine scale for the weight.
Gold is easy compared to diamonds.
The most valuable commodity is still guns, ammo, food, water and energy. You can’t eat gold or diamonds. At the right time, you might be willing to trade a 3 carat diamond for some ammo or a nice cheeseburger or a gallon of gas.
Diamonds feel like they have an oily film on them. This characteristic prevents diamonds from being dirty. Diamonds have a metallic luster like new steel or lead.
The most common colors of diamonds are white, yellow and brown.
