Earth Treasures: Serendibite

By Chisom Ibemere

Serendibite is an extremely rare silicate mineral which is named after the old Persian name for Sri Lanka, “Serendib,” where it was first discovered in the Ratnapura district in 1902.

It was initially mistaken for spinel before being identified as a separate mineral species in 1903.

Serendibite is a rare mineral found in a few locations worldwide. Its primary occurrence is in Sri Lanka, but it has also been found in Myanmar (Burma), Italy, China, and a few other locations.

Serendibite is typically associated with high-pressure metamorphic rocks, such as eclogites or blueschists, which form in subduction zones.

Serendibite is primarily used as an ornamental gemstone due to its rarity and beautiful green or blue-green color.

It is highly sought after by collectors and jewelry enthusiasts for its unique properties. Serendibite gemstones are sometimes faceted into gemstones for use in high-end jewelry. Serendibite gemstones are very scarce due to its extreme rarity and high quality stone.

Serendibite is a complex silicate mineral. It has a vitreous to resinous luster and can occur in shades of dark green, blue-green, and black.

Serendibite is known for its high refractive index, which gives it excellent brilliance and luster when cut and polished. It has a hardness of 6.5 to 7.5 on the Mohs scale, making it relatively durable.

Serendibite is considered one of the rarest and most valuable gemstones globally due to its scarcity and limited availability.

The stone’s value is determined by factors such as color (intense green or blue-green being the most prized), clarity, size, and the absence of inclusions or flaws.

Large, high-quality serendibite gemstones can command very high prices in the market. As a collector’s gemstone, serendibite holds significant value due to its extreme rarity and desirability among gemstone enthusiasts.
