Let’s explore rubies, one of my favorite gemstones.
Ruby is part of the corundum family, a rock-forming mineral. Corundums are naturally transparent in their purest form but can also have colors with certain chemicals. Chromium will make it reddish, creating a vibrant ruby.
Not all red-hued ones, however, fall under rubies. In gemology, the color grade is essential in determining classification. It has to be red to a slightly purplish hue with a medium-dark tone. A lighter or darker stone gives you sapphires, pink and violet tones.
Since color identification can be subjective, be cautious when purchasing rubies. There can be a lot of contention. To add, not all-natural rubies exhibit the red color that we all know and love. Most actually go through heat treatment to enhance it.

Ruby is considered the king of precious stones for a reason. To illustrate, A D flawless diamond versus an untreated, natural, eye-clean ruby, the latter will cost much more on a per carat price.
Most rubies come from Myanmar, Thailand, Vietnam, and Cambodia, and each has its distinct characteristics depending on its origin. For instance, rubies from Myanmar have a pure red color. That’s brought about by a higher presence of marble in its rocks. This makes their rubies the most coveted, usually commanding the highest price.
