How To Tell The Difference?

In order to understand the difference between these two stones, we can look at the color, shape, pattern, clarity, and more. Below we’ll describe all these aspects in detail.

Chemical Composition

Rubies are grouped as corundum. It contains aluminum dioxide in crystalline form and trace amounts of titanium, vanadium, iron, or chromium within its composition. Red diamonds are made of pure carbon. The red coloring on the diamond is purely authentic and not a result of chemical impurities. Other fancy diamonds result from nitrogen and boron within their chemical structure. 


Rubies are richer in color  compared to red diamonds. The most valued ruby is pigeon–red. However, a ruby can display dark-red, purplish, or pink hues depending on the amount of chromium. Red diamonds show a slightly lighter red shade compared to a ruby. Rubies are exclusively red, but the coloration of their secondary hues can vary from brown, pink, orange, or purple.

Pattern and Clarity

Rubies lack cleavage and break at a conchoidal fracture. It’s a brittle stone that can have a vitreous, sub-adamantine, and pearly luster on partings. Its streak is white and is transparent to translucent in clarity. When subjected to light, ruby can display pleochroism, showing purplish and orangey hues from different directions.

Red diamonds have perfect cleavage from all four directions. It breaks with a conchoidal fracture and has an adamantine luster. The stone’s clarity varies from transparent to translucent and shows no pleochroism when observed in light. A ruby is likely to have more flaws and inclusions than a red diamond. These imperfections significantly affect the clarity of the ruby.

Rubies are cleaned at home using warm water and mild soap. They are also durable enough to be cleaned with mechanical methods like ultrasonic and steam cleaners. Diamonds are also safely cleaned at home using warm water and household detergents.
