By Color Garnet

While red is the most common garnet, they occur in nearly every color, with green and blue being the rarest. Blue-green garnets are the most scarce, while vibrant green Tsavorite and Demantoidare highly prized, the latter often featuring unique 'horsetail' inclusions that drive its value. 

Garnet colors range across a fascinating spectrum, defined by their chemical compositions and rarity: 

• Green (Tsavorite & Demantoid): Tsavorite is a vibrant, lush-green grossular garnet. Demantoid, an andradite garnet, is famous for its brilliance, fire, and highly sought-after "horsetail" inclusions. 
• Blue-Green / Blue (Color-Change): Truly pure blue garnets do not exist, but incredibly rare color-changing varieties (hybrids of pyrope and spessartite) shift from blue-green in daylight to purplish-red or pink in incandescent light. 
• Orange (Spessartite): Often called Mandarin garnets, these vivid stones get their brilliant orange hue from manganese. 
• Pink & Purple (Rhodolite / Malaya): Rhodolite offers beautiful raspberry to purplish-red tones, while Malaya garnets display stunning rose-orange to red-violet flashes. 
• Colorless (Leucogarnet): An extremely rare transparent variety of grossular garnet.
