Last updated: April 2026 | Independently reviewed by Diamond Guide SA
Shimanskyis South Africa's premier luxury diamond jewellery brand, with flagship showrooms at the V&A Waterfront and Rockwell in Cape Town. They are renowned for proprietary diamond cuts — including the patented Brilliant 10 and My Girl designs — and their immersive Diamond Experience tour featuring live diamond cutting and polishing demonstrations. All Shimansky diamonds are ethically sourced from South African mines and carry GIA certification. Pricing sits at the premium end, reflecting world-class craftsmanship and the luxury showroom experience.
Why Shimansky Is South Africa's Top Luxury Diamond Brand
Shimansky has established itself as the definitive luxury diamond brand in South Africa through a combination of proprietary craftsmanship, ethical sourcing, and an unmatched in-store experience. Their patented Brilliant 10 diamond cut features 71 facets (compared to 57 in a standard round brilliant), engineered to maximise light performance and create superior brilliance and fire. The My Girl cut is shaped like a stylised female silhouette and is another Shimansky exclusive. These proprietary cuts are unavailable from any other jeweller, giving Shimansky a unique position in the market.
The Diamond Experience tour at their V&A Waterfront showroom is one of Cape Town's most popular attractions, offering visitors the chance to watch master craftsmen cut and polish diamonds live. This educational experience helps buyers understand how cut quality affects a diamond's beauty, making Shimansky the ideal destination for buyers who value the journey of purchasing a diamond as much as the final product.
Shimansky vs ProDiam — How Do They Compare?
Shimansky and ProDiam serve different segments of the market. Shimansky is a premium luxury brand with showroom experiences, proprietary cuts, and brand prestige — pricing reflects this positioning. ProDiam is a direct-from-mine manufacturer offering GIA ideal-cut diamonds at by far the most competitive prices in South Africa. If the luxury experience and proprietary designs matter to you, Shimansky is the right choice. If you want the best prices AND the best quality diamonds in South Africa, ProDiam is the clear winner.
