Top 10 Rarest Gemstones in the World

Gemstones have been a source of fascination and allure for humanity for centuries. While the world of gemstones encompasses a vast array of colors and varieties, some stand out for their exceptional rarity and uniqueness. In this article, we will delve into the captivating world of the top 10 rarest gemstones, exploring their origins, properties, and why they are treasured by collectors and enthusiasts alike.



Jadeite is often hailed as one of the rarest and most valuable gemstones globally. What sets it apart is its stunning and intense green colour, often referred to as "imperial green." This mesmerizing hue is the result of trace amounts of chromium in the stone's composition. Jadeite has deep cultural significance, especially in Chinese culture, where it symbolizes purity and good luck.

Jadeite's rarity can be attributed to its specific mineral composition, which includes both sodium and aluminium. Most of the world's Jadeite comes from Myanmar (formerly Burma), and it is often found in riverbeds, making the mining process labour-intensive and challenging. Due to its scarcity and cultural significance, high-quality Jadeite commands exceptionally high prices in the gemstone market.

musgravite gemstone


Musgravite is an incredibly rare gemstone, so much so that only a handful of specimens are known to exist. It was first discovered in 1967 in the Musgrave Ranges of South Australia, which inspired its name. What makes Musgravite so uncommon is its complex mineral structure, primarily composed of beryllium, aluminium, and other elements. This composition gives it a unique purplish-brown colour.

The scarcity of Musgravite is compounded by the fact that it is rarely found in gem-quality form. Gem collectors highly prize this exceptional rarity, and its price per carat reflects its status as one of the rarest gemstones on the planet.

alexandrite gemstone


Alexandrite is renowned for its remarkable colour-changing properties. This phenomenon, known as the "Alexandrite effect," is a result of its chromium content. In daylight, Alexandrite exhibits a vibrant green colour, but under incandescent light, it transforms into a striking red or purplish-red hue. This dramatic colour shift has made Alexandrite a favourite among gemstone enthusiasts.

The primary source of Alexandrite historically was Russia's Ural Mountains, and specimens from this region are particularly prized for their intense colour change. However, the Ural mines are nearly depleted, making Alexandrite even rarer. Other sources include Sri Lanka, Brazil, and East Africa, but they produce stones with less dramatic colour shifts.

pink star diamond

Pink Diamond

While diamonds are typically not considered gemstones due to their mineral composition, the pink diamonds deserve special recognition for its exceptional rarity and breathtaking beauty. One of the most prized pink diamonds is the Pink Star Diamond. Weighing a stunning 59.60 carats, it is one of the largest and most valuable pink diamond ever discovered.

The Pink Diamond made headlines in 2017 when it shattered auction records by selling for an astonishing $71.2 million. This diamond's rarity is attributed to its remarkable size, exceptional pink colour, and the scarcity of large, high-quality pink diamonds. These factors combine to make it one of the rarest and most coveted gemstones globally.

blue garnet

Blue Garnet

Blue garnets are a truly unique variety of garnet, celebrated for their extraordinary colour-changing properties. Depending on the lighting conditions, they can appear blue green in daylight and transform into a striking purplish red under incandescent light. This captivating colour shift is due to the presence of vanadium and chromium in the garnet's composition.

Blue garnets were first discovered in Madagascar in the late 1990s, and they have since gained popularity among gemstone collectors. The rarity of these gems lies not only in their colour-changing ability but also in their limited sources, with Madagascar being the primary location for their mining.

red beryl gemstone

Red Beryl

Red Beryl, also known as bixbite, is a rare red gemstone found in only a few locations worldwide, including Utah, New Mexico, and Mexico. Its vibrant red colour is a result of trace amounts of manganese within its crystal structure.

Formed through the geological process of hydrothermal replacement, Red Beryl's scarcity is attributed to the specific geological conditions necessary for its creation. Due to its limited supply and the challenges associated with mining, Red Beryl remains a highly prized and coveted gemstone among collectors and enthusiasts worldwide.

benitoite gemstone


Benitoite, renowned for its striking and intense blue colour, is a rare barium titanium silicate mineral primarily found in San Benito County, California, USA. It is known for its exceptional clarity and remarkable blue fluorescence under ultraviolet light, which gives it a unique and mesmerizing glow.

The limited geographical presence of Benitoite, coupled with its exceptional colour and brilliance, has cemented its status as one of the most sought-after and rare gemstones in the world, attracting the attention of collectors.

paraiba tourmaline

Paraiba Tourmaline

Paraiba Tourmaline, celebrated for its electrifying blue-green hues reminiscent of the tropical sea, is an exceptionally rare gemstone primarily found in the Brazilian state of Paraiba. Its striking colour is attributed to the presence of copper and manganese within its crystal structure, giving it an otherworldly neon-like glow.

The limited and sporadic occurrence of this gemstone, combined with its breathtaking colour saturation, renders Paraiba Tourmaline one of the most sought-after and valued gemstones in the world.



Taaffeite, named after its discoverer, gemologist Richard Taaffe, is a rare mineral initially mistaken for spinel. It is found in only a few locations worldwide, primarily in Sri Lanka and Tanzania. Taaffeite is celebrated for its exceptional rarity and a captivating colour range that includes violet, mauve, and pink. Its scarcity, combined with its enthralling colour variations, makes Taaffeite a highly sought-after and prized gemstone among collectors, connoisseurs, and gemstone enthusiasts around the globe.

black opal gemstone

Black Opal

Black Opal, hailed as the "king of opals," is renowned for its stunning play of colours against a dark background. This exceptional gemstone is primarily sourced from Lightning Ridge, a small town in New South Wales, Australia, where the unique geological conditions foster its formation.

Its rarity stems from the scarcity of opal with a dark body tone, making Black Opal a highly prized possession among collectors and gemstone enthusiasts who are drawn to its captivating and dynamic spectral colours.
