How to recognise a genuine ruby? Discover the great beauty of this special stone

For centuries, ruby has been one of the most admired gemstones due to its deep red hue, symbolism, and rich history. Known as the stone containing the essence of life, it adorned royal regalia and played a significant symbolic role in ancient cultures. In this article, you will discover what defines a ruby, what it looks like, its symbolism and how to distinguish a natural gemstone from a synthetic one.

Ruby - the colour and its uniqueness

Its colour is what makes ruby so special. The red spectrum, ranging from deep wine-red tones to the legendary pigeon blood, makes it unmistakable. Ancient civilisations viewed it as a symbol of life’s essence. A ruby is the red variety of corundum, the second-hardest mineral in the world, scoring 9 on the Mohs scale. Its exceptional hue and durability have made it a treasured gemstone throughout history.

The symbolism and allure of ruby

The symbolism of the ruby spans thousands of years. In the Bible, it was associated with beauty and wisdom, while Pliny the Elder, in his book “Natural History”, described its brilliance, hardness, and exceptional properties. A ruby is a gemstone with a rich cultural heritage, linked to passion, courage, and inner strength.

How to Identify a Genuine Ruby?

Recognising a real ruby is not simple and usually requires gemmological expertise. A natural ruby contains inclusions: crystals, rutile needles, or microfractures that testify to its origin. Synthetic rubies tend to be too “clean,” with an almost flawless interior that is rare in nature. There are also glass imitations on the market, which reveal lower durability. To be certain, it is advisable to seek a gemmologist’s assessment or purchase exclusively from trusted manufacturers and reputable jewellers.

Where do ethical rubies come from?

For centuries, the most prized rubies originated from Myanmar (Burma). Today, however, some of its deposits lie in conflict zones, making ethical sourcing a matter of utmost importance. At La Marqueuse, we place great emphasis on responsible, ethical sourcing. Our rubies come from ethical sources, including Mozambique, Madagascar, Sri Lanka, and Thailand. According to GIA reports, Thailand is currently the world’s leading centre for ruby processing.

How much does a ruby cost?

The price of a ruby depends on numerous factors. Colour plays the most significant role; the highly sought-after pigeon blood hue reaches the highest values. Cut quality, natural clarity, lustre, and country of origin are also essential. High-quality rubies may cost several thousand dollars per carat, while exceptionally rare stones can command significantly higher prices.

Frequently Asked Questions

Rubies usually achieve higher prices, especially in the pigeon blood hue, though exceptional emeralds can also be extremely valuable. The reason lies in rarity: the most vividly red rubies are far less common in nature than high-clarity emeralds, and such colour is difficult to find in untreated stones.

It is a ruby grown in a laboratory, with the same chemical composition as a natural one, yet lacking the characteristic inclusions formed in nature.

Top-quality rubies are generally more valuable than sapphires, as intense red is rarer in nature than the finest blue of a sapphire.

The most exceptional rubies can exceed the price of diamonds of the same size, although in standard commercial grades, diamonds typically command higher prices.

Yes. Despite its high hardness, a ruby can crack due to strong impact or pressure. Hardness does not equal resistance to brittleness.

The most reliable method is a gemmological analysis, available at La Marqueuse. We examine the gemstone’s internal structure, inclusions, light response, and any signs of heat treatment. This allows us to determine whether the ruby is natural, synthetic, or modified.

Our rubies come primarily from modern and ethical sources in Mozambique. At present, this is considered the finest alternative to Burmese deposits, which are affected by ongoing armed conflict.

Rubies of this colour, confirmed by certification, are sourced mainly on a bespoke, made-to-order basis.

Rubies in the pigeon’s blood colour, an intense, vivid red, most commonly originate from Myanmar (formerly Burma). Unfortunately, Burmese deposits are currently located in conflict zones. For this reason, many responsible luxury brands such as Tiffany, Harry Winston and  La Marqueuse have consciously chosen to refrain from sourcing them.

Burmese rubies of this colour achieve extraordinary prices on the collectors’ market, often reaching tens of thousands of dollars per carat.

Instead, we select rubies from Mozambique, which are today regarded as the finest alternative to Burmese stones. They are distinguished by their deep, saturated colour, high clarity, and origin from modern, ethically managed sources. Exceptional stones of pigeon’s blood quality do occasionally occur within these deposits.

Burmese rubies, particularly those in the pigeon’s blood colour confirmed by a recognised certificate, are among the most valuable gemstones in the world. The price of a one-carat stone may begin at approximately USD 25,000–50,000, while a two-carat ruby can reach USD 100,000–150,000 or more.

Burmese rubies of a lower colour grade typically range from a few thousand to tens of thousands of dollars per carat, depending on clarity, colour, cut quality, and certification. On the gemstone market, Burmese origin alone can increase the value of the stone by approximately 50% compared to a ruby of similar quality from other sources.
