Loose Diamonds for Sale | Stefan's Jewellery & Gems

Premium Quality Guaranteed

At Stefan’s Jewellery & Gems, we offer an exceptional selection of certified loose diamonds for sale in Cape Town, including round brilliant cuts and a variety of fancy shapes like princess, oval, and emerald cut. Whether you’re searching for a standout centre stone for an engagement ring or an investment-grade diamond, our collection is carefully curated to meet the highest standards of brilliance, quality, and value. We only stock diamonds with exceptionally good to excellent cut grades as this is the main factor in determining light performance and hence beauty.

Every diamond we offer is certified by an independent gemological laboratory recognised by the Diamond Dealers Club of South Africa, ensuring grading that aligns with international standards. According to the Club, “diamonds certified through its network meet the highest global benchmarks”, giving you peace of mind with every purchase.

We focus exclusively on diamonds with excellent to very good cut grades; the most important factor influencing a diamond’s brilliance. As the South African Diamond Producers Association states, “South Africa remains one of the world’s leading diamond producers,” and we are proud to offer certified stones that reflect the country’s rich diamond heritage.

Whether you’re looking for loose diamonds in Cape Town or exploring options for lab diamonds, our team is here to offer expert advice, transparent pricing, and personalised service.
