Garnet vs Ruby vs Spinel

Red gemstones have long been symbols of love, power, and passion. Among the most popular red gems are Garnet, Ruby, and Spinel — each

boasting unique beauty and characteristics. However, due to their similar appearance, especially in deep red hues, these stones are often

confused with one another. In this article, we compare Garnet vs Ruby vs Spinel in terms of appearance, composition, value, symbolism, and

uses to help you better understand and choose the right gem.

Origin & Composition

Ruby

Mineral Group: Corundum

Chemical Formula: Al₂O₃ (aluminum oxide)

Color Cause: Chromium

Hardness: 9 on Mohs scale

Ruby is one of the four precious gemstones (along with diamond, emerald, and sapphire). Its vibrant red color and exceptional hardness make

it ideal for luxury jewelry.

Garnet

Mineral Group: Silicate group (many types like Almandine, Pyrope, etc.)

Chemical Formula: Varies by type (often Fe₃Al₂(SiO₄)₃)

Color Cause: Iron or manganese

Hardness: 6.5–7.5 on Mohs scale

Garnets are a group of minerals rather than a single gem. Red garnet is common, but garnets come in green, orange, and other shades too.

Spinel

Mineral Group: Spinel

Chemical Formula: MgAl₂O₄ (magnesium aluminum oxide)

Color Cause: Chromium (for red spinel)

Hardness: 7.5–8 on Mohs scale

• Spinel was long mistaken for ruby, including in royal crown jewels. It has a similar appearance but different structure and value.
• Color & Appearance
• 
• Ruby: Deep, vivid red with a hint of blue (often called “pigeon blood” red in top-quality stones). Transparent and brilliant.
