1 – Emerald

A variety of the mineral beryl colored green by trace amounts of chromium and sometimes vanadium, emeralds are usually highly included which classify their toughness as poor. When it comes to color, emeralds hues range from yellow-green to blue-green, with the primary hue necessarily being green. When we talk about tone, only gems that are medium to dark in tone are considered emerald. Classifying an emerald for clarity is basically done by eye, if an emerald has no visible inclusions is considered a flawless stone.


2 – Sapphire

A blue gemstone variety of the mineral corundum, an aluminium oxide, sapphire changes color in different light. Color change sapphires are blue in outdoor light and purple under incandescent indoor light, or green to gray-green in daylight and pink to reddish-violet in incandescent light. The one of the largest faceted sapphire in the world is the 423-carat (84.6 g) Logan sapphire in the National Museum of Natural History, in Washington, D.C.


3 – Ruby

A variety of the mineral corundum, a ruby is a pink to blood-red colored gemstone. Ruby is considered one of the four precious stones, together with sapphire, emerald and diamond. Ruby has 9.0 hardness in the Mohs scale, falling behind moissanite and diamond. Generally, gemstone-quality corundum in all shades of red, including pink, are called rubies. However, in the United States, a minimum color saturation must be met to be called a ruby, otherwise the stone will be called a pink sapphire.
