The Five Most Expensive Types of Gemstone in the World

The most expensive gemstones in the world are not simply the rarest stones on Earth. They are the ones where scarcity, beautiful colour, size and a famous origin come together in a single crystal, and where people have wanted them for centuries. Five kinds of gem consistently sit at the top: fine coloured diamonds, ruby, emerald, sapphire and jadeite. Below we look at each one, why it commands such prices, what it means in crystal traditions, and how collectors care for these remarkable stones.

What makes a gemstone expensive?

Before getting to the list, it helps to know how the trade thinks about value. A gemstone is a mineral (or occasionally an organic material, such as pearl) that is beautiful, durable and scarce enough to be cut and worn. If the line between a crystal and a gemstone is new to you, our piece on the difference between crystals and gemstones explains it clearly.

The prices of the most expensive gemstones usually come down to a handful of factors:

• Colour. For coloured gems this matters most. A ruby’s exact shade of red or a sapphire’s depth of blue can multiply its value.
• Clarity. How free the stone is of visible inclusions, the tiny crystals, fractures or fluids trapped inside as it grew. Some inclusions are prized, though, because they prove a stone’s origin or give it a soft, velvety glow.
• Carat weight. A carat is a unit of weight equal to one fifth of a gram. Large fine stones are far scarcer than small ones, so the price per carat rises steeply with size.
• Origin. Certain localities, such as Myanmar for ruby, Kashmir for sapphire and Colombia for emerald, carry a premium because their stones set the standard for quality.
• Treatment. Many gems are heated or otherwise enhanced to improve their colour. An untreated stone of top quality is much rarer and is priced accordingly.
• History and demand. Royal provenance, a famous name or simple fashion can lift a stone well beyond its material value.

One respected Russian gemmological classification ranks jewellery stones in “orders”. It places diamond, ruby, emerald, blue sapphire, alexandrite and natural marine pearls in its first order, which is a useful starting map of where the most valuable gemstones in the world are found.

The five most expensive gemstones in the world

This ranking covers the gems with the highest prices per carat at the very top of the market. In every category, ordinary commercial stones cost a small fraction of the finest ones, so read the list as “the best of each kind” rather than “every stone of this name”.

1. Coloured diamonds

Most diamonds are colourless or faintly tinted, and those are the stones in most engagement rings. The diamonds that set auction records are a different matter: intense pinks, blues and the extraordinarily scarce pure reds. These coloured diamonds are counted among the most expensive gemstones ever sold, and famous named stones such as the Wittelsbach-Graff diamond show how history adds to the appeal of a stone that is already rare.

In crystal traditions, diamond is linked with clarity, commitment and inner strength, and it is often called a “master amplifier” that is believed to intensify the intentions placed on it. Because of its symbolism of permanence, many people choose it to mark a lasting promise.

How people use it: almost always as jewellery, worn daily as a ring or pendant. Few people meditate with a fine diamond, though some collectors keep small rough diamond crystals for that purpose.

2. Ruby

Ruby is the red member of the “big three” precious coloured gems, alongside sapphire and emerald, and it has held a place among the most expensive gemstones for as long as gems have been traded. All fine rubies are rare, but those from Myanmar (formerly Burma) are the benchmark. The geology there produces rubies with very little trace iron, which allows a vivid, pure red and a strong fluorescence that makes the stones seem to glow from within. The most coveted shade is nicknamed “pigeon’s blood”. Rubies from Thailand tend to contain more iron, which pushes them towards darker reds with brownish or purplish tones, though an exceptional Thai stone can still rival the best from Myanmar.

In crystal traditions, ruby is the stone of vitality, passion and courage. It is associated with the root chakra (in yogic tradition, one of seven energy centres along the body, this one at the base of the spine and linked to grounding and security) and sometimes with the heart. Many people wear it as a reminder to act boldly.

How people use it: in rings and pendants, or as a small rough piece held during meditation focused on motivation.

3. Emerald

Emerald’s prized green has made it a royal favourite for centuries, and Colombia is its most celebrated source. Some of the world’s great emeralds tell that story. The Mogul Mughal Emerald, at 217.80 carats, was mined in Colombia and carved in the Mughal Empire in the 1690s; it now rests in the Museum of Islamic Art in Doha. The Patricia Emerald, a 632-carat uncut crystal with twelve sides, was found in Colombia in 1920 and is held at the American Museum of Natural History in New York. Fine emeralds also come from other places: the Carolina Emperor was discovered in the United States in 2009, and the Emerald of Saint Louis came from Austria. Famous stones like these are a big reason emerald stays among the most expensive gemstones today.

In crystal traditions, emerald is the stone of love, loyalty and renewal, tied to the heart chakra and to springtime growth. It is often given to mark partnerships and new beginnings.

How people use it: worn close to the heart as a pendant, or placed in a home’s relationship corner in feng shui-inspired arrangements.

4. Sapphire

Blue is the classic sapphire colour, and the first-order classification above names blue sapphire specifically. Pink sapphire sits a tier lower, and yellow, green and violet sapphires lower again, so colour shifts value considerably. The legendary source is Kashmir, where the stones show a soft, velvety, saturated blue caused by extremely fine inclusions that scatter light inside the gem. A fine Kashmir stone is easily one of the most expensive gemstones a collector could hope to see. Sapphire also gives us some of the most famous named gems: the Star of India, the Logan Sapphire, and the Star of Adam, which weighs 1,404.49 carats (about 281 grams) and is the largest known star sapphire.

In crystal traditions, blue sapphire is linked with wisdom, truth and calm authority, and with the throat and third eye chakras. It has long been a stone of royalty and clergy.

How people use it: as rings and earrings, and in meditation practices focused on clear speech and honest intention.

5. Jadeite

Jadeite is the more valuable of the two materials sold as “jade” (the other is nephrite), and it is the one entry among the most expensive gemstones that is usually carved rather than faceted. It is best known for the bright, electric green called imperial jade, but it also occurs in lavender, yellow, orange-red, blue, black and colourless forms. Its value rests on translucency and texture: the finest material looks almost liquid, as if it were full of water or a drop of coloured oil. Pricing jadeite is more subjective than pricing faceted gems, because the skill of the carver matters so much. The Jadeite Cabbage, a celebrated carving, shows how artistry and material combine.

In crystal traditions, jade has deep roots in Chinese and Mayan cultures, where it was linked with virtue, protection, long life and good fortune. An old Chinese saying holds that gold can be given a price but jade cannot. For more stones with prosperity associations, see crystals for abundance and prosperity.

How people use it: as bangles, pendants and carved talismans worn for protection, often handed down through families.

Rare gems that challenge the top five

Several other stones regularly appear on lists of the most expensive gemstones, and fine examples can outprice ordinary diamonds or sapphires. You can read more about scarce stones in our guide to the most rare gemstones.

Why the most expensive gemstones are not always the rarest

It seems logical that the scarcest stone would be the priciest, but the market does not work that way. Tanzanite is a good example: it is much rarer than sapphire, yet a fine tanzanite can rival a fine sapphire’s colour at a fraction of the price. Price needs demand as well as scarcity, and demand grows from history, familiarity and a steady supply that lets jewellers build collections around a stone. A gem so rare that few people have ever seen one may be prized by collectors and still never reach the prices of ruby or emerald.

A worked example: two rubies of the same size

Picture two rubies of the same carat weight lying side by side. The first is from Thailand, heat-treated, a deep slightly brownish red, with a few visible inclusions. The second is from Myanmar, untreated, a vivid glowing red, and comes with a laboratory report confirming both facts. Both are genuine rubies. The second, though, may be worth many times the first, because it combines the most desired colour, a benchmark origin and the absence of treatment, and very few stones in the world have all three. Size then multiplies the gap: doubling the weight of a top stone can raise its price per carat, not just its total price.

This is why lists of the most expensive gemstones talk about “fine” or “top” examples. The name of the gem only starts the conversation.

Common mistakes when judging valuable gems

Most errors around the most expensive gemstones come from trusting a name or a colour without asking more questions.

1. Assuming every red stone is a ruby. For centuries, red spinels were mistaken for rubies. The Black Prince’s Ruby on the British Imperial State Crown and the Timur Ruby are both actually spinels, and the Timur stone was believed to be a ruby until 1851.
2. Ignoring treatment. Heat and other treatments are common and accepted when disclosed, but they change value. Always ask whether a stone has been treated.
3. Confusing natural and lab-grown. Lab-grown gems such as synthetic alexandrite have the same chemistry as natural stones and cost far less. They are lovely, but they are not the stones that make up the most expensive gemstones lists.
4. Judging by the name alone. “Emerald” or “sapphire” on a label says nothing about quality. A pale, heavily included sapphire is an affordable stone.
5. Buying a high-value gem without a report. For a significant purchase, an independent gemmological laboratory report confirming identity, origin and treatment is standard practice.

How to care for the most expensive gemstones

Even the most expensive gemstones can chip, scratch or lose their polish if treated carelessly. A few habits go a long way:

• Store pieces separately. Gems differ in hardness, which is measured on the Mohs scale, a ranking from 1 to 10 of how well a mineral resists scratching. A harder stone will scratch a softer one, so keep each piece in its own pouch or lined compartment.
• Clean gently. Lukewarm water, a drop of mild soap and a soft brush suit many set gems. Avoid ultrasonic cleaners, steam and harsh chemicals unless a jeweller confirms your particular stone and its treatment can take them.
• Take rings off for hard work. Gardening, the gym and cleaning with household chemicals are where most damage happens.
• Treat organic gems with extra care. Pearls and opals are more delicate than faceted mineral gems; keep them away from perfume, hairspray and prolonged soaking.
• Never make gem elixirs or let pets and children handle small stones. Small gems are a choking hazard, and many stones are unsuitable for contact with drinking water.

Many people also like to energetically cleanse their jewellery in line with crystal traditions. Gentle methods such as sound, smoke or moonlight suit valuable pieces far better than salt or water soaking; see how to cleanse your crystals and charging crystals under the full moon for ideas.

Enjoying precious stone traditions on any budget

You do not need an auction budget to explore the meanings behind the most expensive gemstones. In crystal traditions, a stone’s worth lies in the attention and intention you bring to it, not its price. Many collectors start with affordable stones and build from there:

• Choose by colour and meaning. If ruby’s vitality speaks to you, other red stones carry similar associations. Our guide to the power of a crystal by its colour explains how colour links stones across traditions.
• Start with a varied set. A mixed kit is an easy way to get to know many stones at once; you can look at crystal collector kits at Spirit Magicka, the journal’s own crystal shop.
• Enjoy colourful, affordable minerals. Fluorite comes in green, purple and blue tones that echo the precious gems, and many people keep it on a desk for focus; you can browse fluorite at Spirit Magicka.
• Display raw beauty. Clusters and geodes (rocks with crystal-lined hollows inside) bring the wonder of crystal growth into a room for very little; see clusters and geodes at Spirit Magicka.
