The Allure of Black Diamonds

Ring with black diamonds from BAUNAT
Authentic black diamonds, also known as carbonados, are rare treasures of nature that beautifully illustrate the term 'exceptional'. These diamonds are mined in alluvial deposits in Brazil and the Central African Republic, boasting a distinct porosity that sets them apart from their colourless, and other coloured counterparts.

The Origin of Black Diamonds: A Celestial Connection

Unlike other precious stones, black diamonds are only found in three places globally - Brazil, the Central African Republic and South Africa. According to popular scientific theories, these diamonds are remnants of a meteorite that blessed our planet millions of years ago.

Types of Black Diamonds: Natural, Treated and Lab-Grown

Black diamonds you’ll see for sale generally belong to one of three groups: natural carbonado, treated black diamonds, and lab-grown black diamonds. Natural carbonado are true polycrystalline stones formed in nature; they keep the complex mineral mix of their origin and occur only in a few places. Treated black diamonds begin as natural stones but receive surface or structural procedures to intensify or even out the black colour. Lab-grown black diamonds are produced in controlled conditions to reproduce the black look without being mined.  

Common treatment methods and what they mean

Dyeing or impregnation uses the stone’s pores and tiny fractures introduce colourants; the result can be an even black surface, but it may wear or change with aggressive cleaning. Irradiation alters colour by changing the crystal lattice; the change can be stable, but it is an artificial modification that should be disclosed. High-pressure, high-temperature treatment (HPHT) can also darken or alter a diamond by affecting internal defects; it is a laboratory process used to improve or standardise appearance. Each method changes how a stone looks and has implications for disclosure, long-term stability and market value, which is why clear information about treatments matters to buyers. 

Rarity and pricing implications

Natural carbonado remain the rarest of the three categories, and that scarcity usually carries a higher relative premium compared with treated or lab-grown alternatives. Treated black diamonds are common in retail because treatment lets more stones present a uniform black face. Lab-grown black diamonds can reproduce the visual effect at scale, placing them in a different supply and price bracket than natural carbonado. Expect noticeable differences in rarity and relative value between natural carbonado, treated stones and lab-grown options. 

BAUNAT’s sourcing and disclosure practice


BAUNAT records the nature of the stones used in its jewellery so customers can make an informed choice. When a piece contains a natural carbonado this appears in the stone information; if a black diamond has been treated or is lab-grown, that is stated as well. This factual approach sets clear expectations without making a blanket value judgment across categories.

What Does a Black Diamond Signify?

Each coloured gemstone carries a unique symbolism. In the case of black diamonds, they signify action, passion, energy, authority and power. However, the true significance of your handcrafted BAUNAT black diamond jewellery lies in its rarity and value, embodying your genuine love.

The Rising Demand for Black Diamond Engagement Rings

Despite their unorthodox appeal, black diamonds are increasingly becoming a popular choice for engagement and wedding rings among men and women alike. BAUNAT’s black diamond engagement rings exude an uncommon charm that's both elegant and intriguing, making them an ideal gift for your significant other. 

The Value of Black Diamonds

Although black diamonds belong to the fancy-coloured category, their price is comparatively affordable due to their unusual light absorption properties. Yet, their rarity makes them as desirable as pink or blue diamonds, setting them at a comparable price point to our traditional colourless diamonds.

The Majestic Black Diamonds in History

While black diamonds might not be the most common choice, several stones have gained worldwide recognition over the years. The Black Amsterdam Diamond, The Black Orlov and the Spirit of the Grisogono are among the most notable black diamonds till date.

Structure, Toughness and Working Carbonado


Carbonado is not a single crystal like most gem diamonds but a polycrystalline aggregate: a mosaic of tiny diamond crystallites bound with other carbon phases. That microstructure brings notable porosity and a fine-grained texture, and importantly it increases fracture toughness compared with many monocrystalline gem diamonds. Toughness describes resistance to crack propagation; hardness measures resistance to surface indentation. Carbonado can be hard at the microscopic scale while resisting breakage better than some single-crystal stones.

Those material differences matter when preparing carbonado for jewellery. Cutting and polishing are often more challenging because the stone’s many internal boundaries react differently under a cutter; achieving a high polish or faceted finish can require specialised techniques and experienced lapidaries. Historically, the toughness and aggregate structure led many carbonados to industrial use rather than gemstone use. Today, when carbonado is set in rings, cutters and setters take extra care with sawing, shaping and the final polish to reveal the best surface without creating stress points.

For settings and long-term wear, the distinction between toughness and hardness guides sensible choices. A setting that protects the girdle and major facets reduces the chance of impact damage to any faceted or shaped carbonado. Bezel styles and protective prongs that surround the stone provide that physical security while still showing the dark sparkle; by contrast, designs that leave the stone very exposed increase the likelihood of contact with hard surfaces. We do not recommend tension settings; choose mountings that cradle and protect the stone and that allow a professional setter to secure it without uneven stress. 


Care note

Carbonado benefits from the same basic care as other diamonds: gentle cleaning with mild soap and water, avoid harsh chemicals that could affect surface treatments, and periodic inspection by a trusted jeweller to confirm the setting remains secure.
