Hope Diamond - The Hope Diamond, now in the Smithsonian’s National Museum of Natural History, is a deep-blue stone of about 45.52 carats. Its documented history stretches to the 17th century and includes French royal ownership and later private collectors, which has helped shape its public fame.

Koh-i-Noor - The Koh-i-Noor originates in South Asia and passed through many hands over centuries, moving between regional dynasties and empires. Today a notable cut of the stone is part of the British crown jewels; its long, contested history continues to attract attention.

Dresden Green - The Dresden Green is a natural green diamond of roughly 41 carats that has been in European collections for centuries. Its unusual colour and long exhibition history made it a highlight of royal treasuries and museum displays.

Orlov Diamond - The Orlov, a large rose-cut stone, became famous as part of the Russian imperial sceptre. Its 18th-century provenance connects South Asian mining with later European collection history.

Provenance influences value because documented ownership and exhibition history confirm authenticity and create a narrative collectors and museums prize. Stones with well-established histories routinely attract higher bids and more scholarly and media attention.

Coloured diamonds get their hues from trace elements or from tiny distortions in the crystal lattice. Nitrogen, for example, can produce yellow tones; boron can produce blue; and intense pressure that deforms the lattice can yield pinks and reds. Those specific conditions occur only rarely during the slow, high-pressure processes that form gem-quality diamonds, which is why vivid natural colours are uncommon.

A few famous stones make the point. The Moussaieff Red, at 5.11 carats, is one of the very few natural red diamonds known and is prized for that extreme rarity. The Pink Star, a fancy vivid pink of 59.60 carats, proved exceptional because it combines large size with strong colour intensity  -  a rare pairing. There are likewise a handful of orange and orange-red stones that command attention precisely because pure orange and red tones are so scarce.

Auction houses such as Christie’s and Sotheby’s routinely show how intensity, size and a clear natural origin interact to set prices. Provenance  -  documented ownership or exhibition history  -  also matters: a well-documented past can increase collector interest and push a stone’s final bid higher. Collectors and museums value both the scientific rarity and the story each stone carries, which is why coloured diamonds often stand out in the market.

1. The English word “diamond” traces back to the Greek adamas, meaning invincible or untamed; this derivation appears in standard dictionaries and in early modern English usage, where authors linked the term to the mineral’s notable hardness and symbolic meanings. References in historical natural histories and lexicons record the word’s adoption across European languages from the late medieval period onward.

2. Recently it has become very popular to buy jewels set with coloured diamonds. Did you know that red is by far the rarest colour for a diamond? And thereby the most expensive! A perfect example is the red Moussaieff diamond of 5.11 carat that was sold at an auction for 8 million American dollars.
3. The average (mined) diamond is 1 to 3 billion years old. So, that means that the diamond processed in your favourite jewel is older that the oldest dinosaur.

4. The term carat comes from the carob seed, which merchants historically used as a convenient weight comparison because the seeds tended to have a consistent mass. As medieval and early modern trade networks expanded, jewellers and gem traders adopted the carob-based measure; over time that trader’s reference was standardized into the metric carat in use today. Etymological sources and metrology references document this shift from a seed-based trade convention to an internationally recognized weight standard.

5. It used to be far from common to buy a diamond ring for your fiancée. The first diamond engagement ring ever given, was by archduke Maximillian of Austria to Maria of Burgundy in 1477.
