Here's a breakdown of the key differences between buying diamonds from Africa, Australia, Canada, Russia and India. Each origin boasts its own unique character, price points, and historical allure.

Let's take a virtual trip around the diamond world, shall we?



  • Locations: Botswana, South Africa, Namibia, Angola, and Sierra Leone are major players.

  • Value: Generally, African diamonds fetch a premium due to their exceptional quality and size. Think Type IIa gems like the Cullinan, the largest rough diamond ever found weighing 3016 carats.

  • Famous Finds: The Cullinan (South Africa), the Star of Sierra Leone (Sierra Leone), and the De Beers Centenary (South Africa) are just a few legends born from African soil.


  • Location: Argyle mine in Western Australia was the world's biggest diamond producer for decades, known for its pink-coloured diamonds. It produced more than 800 million carats of rough diamonds from 1983 to 2017.

  • Value: While Argyle closed in 2020, Australian diamonds can still command good prices, especially pink diamonds.

  • Famous Finds: The Argyle Pink Jubilee, a tennis ball-sized pink diamond, and the Argyle Violet, the rarest of the rare violet diamond, are Australian treasures. 

  • Gem Quality: Generally high, with Argyle's pinks and champagnes commanding the highest prices.

  • Ethical Concerns: Generally good practices, with Kimberley Process adherence and strong government regulations.

  • Price: Generally higher due to exclusivity, especially for coloured diamonds.

  • Primarily white diamonds, known for their clean and colourless nature.

  • Gem Quality: Consistent high quality, known for clarity and brilliance.

  • Ethical Concerns: Strong regulations and Kimberley Process adherence ensure ethical sourcing.

  • Price: Competitive, with good value for the quality.

  • Location: Northwest Territories is home to the Diavik and Ekati mines, known for their ethical and conflict-free diamonds.

  • Value: Canadian diamonds tend to be slightly less expensive than African stones but still offer excellent quality and ethical sourcing.

  • Famous Finds: The Canadian Dream, a 54.58-carat flawless diamond, and the Foxfire, are Canadian gems. 


  • Location: Yakutia region in Siberia is the source of most Russian diamonds, known for their large size and industrial applications.

  • Value: Russian diamonds can be more affordable than other origins, but quality varies greatly. Be sure to do your research!

  • Famous Find: The Alrosa Diamond and the Jubilee Diamond.

  • Major producer of large white diamonds

  • Gem Quality: Quality varies, with some exceptional stones but also a higher percentage of lower-quality diamonds.

  • Ethical Concerns: Concerns exist due to limited transparency and potential involvement in non-Kimberley Process diamonds.

  • Price: This can be competitive for large stones, but caution is advised due to potential quality inconsistencies.


India has a long history of diamond mining, with the famed Golconda mines producing some of the most legendary diamonds in history.

  • Origin: Not a major producer of rough diamonds, but a global leader in diamond cutting and polishing.

  • Gem Quality: Skilled artisans can create exquisite cuts and finishes, adding value to diamonds from other countries.

  • Ethical Concerns: Concerns about labour practices and diamond trade transparency exist. Careful sourcing from ethical and certified cutters is crucial.

  • Price: Can be more affordable for finished diamonds due to lower labour costs, but quality varies greatly.

  • Location: Major centres in Surat and Mumbai. 

  • Value: Indian diamonds are often smaller and more affordable, but they can still be stunning, especially when cut and polished by skilled artisans.

  • Famous Finds: The Koh-i-Noor, one of the largest cut diamonds in the world, and the Taj Mahal Diamond, a pear-shaped gem gracing the Mughal crown, have Indian origins. 

  • Considerations: Be wary of diamond treatments and ensure certifications verify authenticity and quality.

Remember, the most important factor is buying from a reputable source that guarantees ethical sourcing and quality.

A few additional factors to consider:

  • Certification: Look for diamonds certified by independent organizations like the Gemological Institute of America (GIA) or the International Gemmological Institute (IGI). These certifications ensure authenticity, quality, and ethical sourcing.

  • The 4Cs: Cut, Colour, Clarity, and Carat weight are crucial factors influencing a diamond's value and beauty. Choose a diamond that excels in these aspects based on your budget and preferences.

  • Personal preference: Ultimately, the best diamond is the one that speaks to your heart and fits your budget. Consider your fiancé's style and preferences when making your decision.

  • Specific needs: Consider your desired diamond size, colour, clarity, and cut to guide your choice of origin.

  • Reputation: Deal with reputable and certified dealers who prioritize ethical sourcing and transparency.

  • Investment potential: Certain diamonds, particularly rare colours or cuts, can hold significant investment value.


This is just a glimpse into the fascinating world of diamond origins. Each region has its own unique story to tell, and the value of a diamond depends on a multitude of factors beyond its origin. When making your purchase, prioritize ethical sourcing, reputable dealers, and gemmological certificates to ensure you're getting a diamond that aligns with your values.

Remember, thorough research and understanding the 4Cs will help you make an informed decision and choose the ideal diamond for your engagement ring.

At the end of the day, the most important thing is that you love your diamond. If it speaks to you, makes your heart skip a beat, and fits your budget, then that's the one for you! Don't get pressured into buying something that doesn't feel right.

Now go forth and sparkle responsibly! Good luck!
