They were then brought to the surface by volcanic activity to eventually be discovered by humans, firstly in ancient India.&nbsp;<\/p>\n\n\n\n<p>It\u2019s&nbsp;pretty mind-blowing&nbsp;to think that some natural diamonds are between 90 million and 3.5 billion years old, meaning they were formed before&nbsp;humankind&nbsp;even existed.&nbsp;But this is exactly what appeals to buyers and investors and<strong>&nbsp;<\/strong>sets&nbsp;natural diamonds apart from their&nbsp;synthetic counterparts, <a href=\"https:\/\/adiamondisforever.com\/en-in\/education\/natural-vs-lab-grown-diamonds-whats-the-difference\/\">laboratory-grown diamonds<\/a> (also called LGDs).&nbsp;<\/p>\n\n\n\n<p>As natural diamonds can only be found in certain parts of the world (the biggest diamond mines are found in Botswana, Canada,&nbsp;Russia&nbsp;and South Africa, where volcanic sites have the right conditions for recovery),&nbsp;they\u2019re&nbsp;exceptionally rare and precious.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The power of uniqueness in investment-grade natural diamonds<\/h2>\n\n\n\n<p>Much like snowflakes,\u00a0leaves\u00a0and us humans, no two natural diamonds are\u00a0exactly the same.

They stand for carat weight,\u00a0colour, clarity and cut. All four play a role in not just appearance, but also long-term\u00a0diamond investment\u00a0potential.\u00a0<\/p>\n\n\n\n<p>Graded on individual scales, the 4Cs are crucial in&nbsp;determining&nbsp;a&nbsp;diamond\u2019s value&nbsp;as they collectively define a natural diamond\u2019s quality,&nbsp;rarity&nbsp;and perceived beauty.&nbsp;<\/p>\n\n\n\n<p>Cut affects how well a diamond reflects light, directly influencing its brilliance and sparkle.&nbsp;Colour, in fact, measures the absence of&nbsp;colour, with the most valuable diamonds being&nbsp;colourless&nbsp;due to their rarity in nature. Clarity assesses the presence of internal flaws (called inclusions) or external blemishes, with fewer imperfections increasing the diamond\u2019s worth \u2013 again, because flawless natural diamonds are rarer.&nbsp;Carat weight&nbsp;indicates&nbsp;the diamond\u2019s weight, with larger stones being limited and more expensive.&nbsp;<\/p>\n\n\n\n<p>These four metrics&nbsp;provide&nbsp;a standardised way to assess and compare diamonds, ensuring transparency and consistency in pricing and quality evaluation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why diamond certification protects value<\/h2>\n\n\n\n<p>If&nbsp;you\u2019re&nbsp;buying a natural diamond as an investment, with the possibility of reselling it in the future,&nbsp;certified diamonds&nbsp;are&nbsp;a must.&nbsp;Having&nbsp;all the right paperwork is imperative.&nbsp;&nbsp;<\/p>\n\n\n\n<p>Polished diamonds larger than 0.3 carat in size come with their own individual report documenting their origin and grading for each of the 4Cs. These are issued by an independent&nbsp;gemmological&nbsp;institute, such as the&nbsp;De Beers Institute of Diamonds. (IOD),&nbsp;Gemological Institute of America (GIA), American Gem Society (AGS),&nbsp;and&nbsp;IGI (International Gemological Institute)&nbsp;&nbsp;<\/p>\n\n\n\n<p>To ensure&nbsp;there\u2019s&nbsp;never any mix-up about which report refers to which diamond, most diamonds will have an inscription on either their girdle (the \u2018waist\u2019 of the diamond) or their table (the top&nbsp;facet) that corresponds with its report.&nbsp;<\/p>\n\n\n\n<p>A grading report is essential when re-selling a diamond because it proves authenticity, something which every buyer will be on the lookout for.&nbsp;<\/p>\n\n\n\n<p>This precise grading is, in most cases, only applied to natural diamonds. Given that most lab-grown diamonds occupy a narrow range of quality characteristics, the GIA has introduced a more streamlined assessment method for LGDs, classifying them as either Standard or Premium based on their quality and craftsmanship.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Sources<\/h3>\n\n\n<ol class=\"wp-block-footnotes\"><li id=\"e1a61967-67c8-491c-bf89-caecb2b00a38\">Hatton-garden-jewellers.co.uk, The value of diamond over time <a href=\"#e1a61967-67c8-491c-bf89-caecb2b00a38-link\" aria-label=\"Jump to footnote reference 1\">\u21a9\ufe0e<\/a><\/li><li id=\"e249936b-99de-4d54-85ff-48103177cb7b\">Sothebys.com, The five most expensive pink diamonds <a href=\"#e249936b-99de-4d54-85ff-48103177cb7b-link\" aria-label=\"Jump to footnote reference 2\">\u21a9\ufe0e<\/a><\/li><li id=\"30a1b55c-1552-4ca5-98a0-0c0ec5a35102\">Sothebys.com, The five most expensive pink diamonds\u21a9\ufe0e <a href=\"#30a1b55c-1552-4ca5-98a0-0c0ec5a35102-link\" aria-label=\"Jump to footnote reference 3\">\u21a9\ufe0e<\/a><\/li><li id=\"36d61d75-7b2a-44ca-8a88-351edb89fbbf\">Hutchinsonscott.co.uk, Factors that impact the value of antiques <a href=\"#36d61d75-7b2a-44ca-8a88-351edb89fbbf-link\" aria-label=\"Jump to footnote reference 4\">\u21a9\ufe0e<\/a><\/li><li id=\"3eaf41e4-a480-4391-bf96-6019e4172e53\">Media.bain.com\/Images\/PR_BAIN_REPORT_The_global_diamond_industry.pdf <a href=\"#3eaf41e4-a480-4391-bf96-6019e4172e53-link\" aria-label=\"Jump to footnote reference 5\">\u21a9\ufe0e<\/a><\/li><li id=\"fdb7e912-3956-424c-8f5f-d9356f6d48ff\">Debeersgroup.com\/~\/media\/Files\/D\/De-Beers-Group-V2\/documents\/reports\/2022\/DeBeers_DIR2022.pdf <a href=\"#fdb7e912-3956-424c-8f5f-d9356f6d48ff-link\" aria-label=\"Jump to footnote reference 6\">\u21a9\ufe0e<\/a><\/li><li id=\"1ea5f038-9352-4e52-bd0e-44d9a130ca62\">Bain.com, The global diamond industry 2020\u201321 <a href=\"#1ea5f038-9352-4e52-bd0e-44d9a130ca62-link\" aria-label=\"Jump to footnote reference 7\">\u21a9\ufe0e<\/a><\/li><li id=\"19700c0a-b3a6-4fa4-b646-32d275efb1d2\">Debeersgroup.com\/~\/media\/Files\/D\/De-Beers-Group-V2\/documents\/reports\/2022\/DeBeers_DIR2022.pdf <a href=\"#19700c0a-b3a6-4fa4-b646-32d275efb1d2-link\" aria-label=\"Jump to footnote reference 8\">\u21a9\ufe0e<\/a><\/li><\/ol>","protected":false},"excerpt":{"rendered":"<p>How do diamonds measure up in terms of financial value?
