Both natural and lab-grown diamonds are made of pure carbon atoms arranged in a cubic crystal structure. They share the same chemical composition (C), the same hardness (10 on the Mohs scale), the same refractive index, and the same optical properties.

They reached the surface through volcanic eruptions called kimberlite pipes \u2014 the same geological formations that make the Antwerp diamond district unique as a trading hub.

Demand from India and China continues to grow.<\/p>\n<p>For investment-grade natural diamonds (round brilliant, IF\u2013VS1, D\u2013F colour, 0.5\u20132ct range), the secondary market is liquid. Dealers, jewellers, and auction houses actively buy. This liquidity is what distinguishes a diamond as a store of value versus a depreciating asset.<\/p>\n<h3>Lab-grown diamonds: the depreciation reality<\/h3>\n<p>Lab-grown diamonds are a manufactured product. Like any manufactured product \u2014 smartphones, flat-screen televisions, computer chips \u2014 the cost of production falls as technology improves and scale increases. There is no floor. The price of a lab-grown diamond today reflects the current cost of energy, equipment, and labour at scale. In five years, those costs will likely be lower.<\/p>\n<p><strong>This is not a theoretical concern.<\/strong><span>\u00a0<\/span>Buyers who purchased lab-grown diamonds in 2019\u20132021, when they were still priced at 50\u201360% of natural equivalents, are sitting on stones worth 10\u201320% of what they paid \u2014 wholesale. If you purchased for emotional or aesthetic reasons, this may not matter.

The reality is considerably more nuanced \u2014 and the diamond industry has changed dramatically since the early 2000s \"blood diamond\" era.<\/p>\n<h3>Are lab-grown diamonds more ethical?<\/h3>\n<p><a href=\"https:\/\/diamantwerp.be\/kimberley-process-diamonds\/\">The Kimberley Process Certification Scheme<\/a>, established in 2003, has reduced conflict diamond trade to below 0.1% of the global diamond supply. For certified diamonds purchased from reputable dealers \u2014 especially those from Antwerp, which operates the world's most rigorous triple-control Diamond Office system \u2014 ethical provenance is not a meaningful concern.<\/p>\n<p>More importantly:<span>\u00a0<\/span><strong>diamond mining supports the livelihoods of millions of people<\/strong><span>\u00a0<\/span>in Botswana, Namibia, South Africa, and Canada. These are legitimate, regulated industries providing employment, healthcare, and infrastructure in communities where few alternatives exist. Choosing a lab-grown diamond doesn't automatically help those communities \u2014 it removes a revenue stream from them.<\/p>\n<h3>Are lab-grown diamonds more sustainable?<\/h3>\n<p>This claim deserves scrutiny. The two most common lab-growing methods \u2014 HPHT and CVD \u2014 require<span>\u00a0<\/span><strong>enormous amounts of energy<\/strong>. The majority of this energy, especially in Chinese and Indian factories where most lab-grown diamonds are now produced, comes from fossil fuels. Carbon footprint analyses of individual lab-grown diamonds versus mined diamonds are mixed, and independent lifecycle assessments show the picture is not as clear-cut as marketing suggests.<\/p>\n<p>Natural diamond mining, while land-intensive, covers a remarkably small total surface area globally, and major mining companies have made significant investments in land restoration.<span>\u00a0<\/span><strong>The most sustainable diamond of all, if sustainability is your primary concern, is a second-hand or vintage stone<\/strong><span>\u00a0<\/span>\u2014 a position advocated by independent analysts including <a href=\"https:\/\/www.paulzimnisky.com\" target=\"_blank\" ref=\"noopener noreferre\"r>Paul Zimnisky<\/a>.<\/p>\n<\/div><\/div>\n\n<div class=\"et_pb_code_9 et_pb_code et_pb_module\"><div class=\"et_pb_code_inner\"><style>\n\/* \u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\n   DIAMANTWERP \u2014 Antwerp Perspective Block\n   Divi Code Module \u2014 complete drop-in\n   \u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500 *\/\n\n\/* 1.

Wholesale prices for lab-grown stones have fallen approximately 95% as production capacity (primarily from China and India) has scaled far faster than demand. Retailers who purchased lab-grown inventory at 2021 prices have faced significant losses. Natural certified diamonds, by contrast, have maintained broadly stable wholesale prices over the same period and have a functioning secondary market through auction houses, dealers, and online platforms.\"\n      }\n    },\n    {\n      \"@type\": \"Question\",\n      \"name\": \"Are lab-grown diamonds better for the environment than natural diamonds?\",\n      \"acceptedAnswer\": {\n        \"@type\": \"Answer\",\n        \"text\": \"It depends entirely on the energy source used in production. HPHT and CVD lab-grown diamond production is extremely energy-intensive. Facilities powered by renewable energy have a lower carbon footprint than mining; facilities powered by coal (as many in China and India are) may have a higher footprint than modern certified mines. Natural diamond mining, under Kimberley Process certification, also funds environmental restoration projects and local communities in producing countries. Neither option is automatically more sustainable \u2014 the supply chain matters.\"\n      }\n    },\n    {\n      \"@type\": \"Question\",\n      \"name\": \"What changed with GIA grading for lab-grown diamonds in October 2025?\",\n      \"acceptedAnswer\": {\n        \"@type\": \"Answer\",\n        \"text\": \"In October 2025, GIA updated its grading reports for lab-grown diamonds. Previously, GIA graded lab-grown stones with the same specific cut, colour, and clarity grades used for natural diamonds (e.g. D, VVS1, Excellent). Under the new system, GIA replaced those specific grades with descriptive range terms \u2014 for example, colour is now reported as a range rather than a single letter grade. GIA stated this change reflects the distinct market position of lab-grown diamonds. Buyers who previously relied on precise GIA grades for lab-grown stones should be aware that future reports will use a different format.\"\n      }\n    },\n    {\n      \"@type\": \"Question\",\n      \"name\": \"Why does Diamantwerp only sell natural diamonds?\",\n      \"acceptedAnswer\": {\n        \"@type\": \"Answer\",\n        \"text\": \"Diamantwerp has specialised exclusively in certified natural loose diamonds since 1987 \u2014 before lab-grown diamonds existed commercially. Our expertise, our supplier relationships in the Antwerp diamond district, and our assessment of long-term value are all anchored in natural stones. We sell only diamonds certified by GIA, HRD Antwerp, and IGI. We believe natural diamonds remain the only option with a proven long-term resale market and genuine rarity. We are transparent about this position: we do not sell lab-grown diamonds, not because they are not real diamonds, but because they fall outside our area of expertise and our view of lasting value.\"\n      }\n    }\n  ]\n}\n<\/script><\/div><\/div>\n<\/div>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"","protected":false},"author":9,"featured_media":22491,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6153],"tags":[6133,6134,1577,6132],"class_list":["post-22490","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-informatie","tag-antwerp-diamonds","tag-diamond-buying-guide","tag-gia","tag-lab-grown-diamonds"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.4 (Yoast SEO v27.4) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>Lab Grown vs Natuurlijke Diamanten: Complete 2025 Gids \u2014 Diamantwerp<\/title>\n<meta name=\"description\" content=\"Lab grown of natuurlijke diamant?
