Tanga garnet is a trade name for

vibrant pink, rose, or reddish-purple rhodolite garnets sourced from the Tanga region of Tanzania. Known for exceptional brilliance and often exhibiting a soft, romantic blush color, these gemstones frequently display high clarity and are typically mined in the Umba Valley.

Key Characteristics:

• Color: Ranges from soft pink, bright rose, to deep pinkish-purple and intense red.

• Origin: Tanga region, Tanzania, often associated with the Umba Valley.

• Composition: Primarily rhodolite (a mix of pyrope and almandine), though sometimes linked to Malaya garnet.

• Clarity: Generally high (often "loupe clean"), allowing for high light refraction and brilliance.

• Cut: Often featured in specialty cuts like the SunBurstTM cut to maximize sparkle.

• Durability: Suitable for daily wear, possessing the same hardness as other garnets (approx. 7–7.5 on Mohs scale).

These garnets are considered rare and are popular for, among other uses, creating vibrant center stones for engagement rings due to their unique, intense colors.
