Ruby vs. Garnet: What's the Difference?
Edited by Harlon Moss || By Janet White || Published on January 22, 2024
Ruby is a precious, red-colored gemstone made of corundum, highly valued for its rarity and vibrant hue. Garnet is a group of silicate minerals available in various colors, commonly seen in red, valued for its use in jewelry and industrial applications.
Key Differences
Ruby, a variety of the mineral corundum, is renowned for its deep red color and exceptional hardness, second only to diamonds. Garnet, in contrast, refers to a group of minerals with a similar crystal structure but varying in color and composition, often found in shades of red, but also in green, yellow, and other colors.
The color of a ruby is its most distinguishing feature, typically a vibrant, deep red, often with a hint of blue, deriving its color from chromium. Garnets, although commonly known for a similar red hue, can display a wider range of colors, including orange, green, and purple, depending on the specific mineral composition.
In terms of rarity and value, rubies are generally more prized and expensive, especially those with a pigeon-blood red color and high clarity. Garnets, while also cherished in jewelry, are more abundant and thus typically more affordable than high-quality rubies.
When it comes to usage, rubies are primarily used in fine jewelry and are often associated with luxury. Garnets, besides being used in jewelry, have diverse industrial applications, such as in abrasive materials due to their hardness and durability.
Historically and culturally, rubies have been associated with power, wealth, and passion, often featured in royal insignia and crowns. Garnets, with a history dating back to ancient civilizations, have been used as gemstones and abrasives and are believed to have various healing properties.
