Project Overview
If your jewelry brand leads diamond sales in China, operates over 5,000 stores, holds a Shenzhen Stock Exchange listing, and ranks among Deloitte’s top 100 global luxury companies, but your international website does not reflect that standing to a buyer in London or New York encountering the brand for the first time, you are leaving your highest-growth markets to competitors already established there. Chow Tai Seng Jewelry Co., Ltd., established in 1999, required an international platform that communicated its scale and credibility to buyers with no prior familiarity.
A luxury jewelry brand entering international e-commerce markets faces a trust problem that domestic brands do not. A Chinese jewelry brand arriving in the digital spaces of the US, UK, or Europe competes against Tiffany, Cartier, and Graff on first impression alone. If the product photography, diamond data depth, checkout experience, and content quality of the international website do not match the standard those brands set, the buyer makes a negative judgment from a single page visit and does not return to investigate the brand further.
A catalog of over 10,000 GIA-certified loose diamonds creates a specific operational problem for luxury jewelry e-commerce: two buyers researching the same certified stone must not both be able to complete a purchase for it. Without a system holding a stone exclusively during a buyer’s evaluation session, the brand risks either fulfilling two orders for the same stone or declining a confirmed purchase after the fact, both of which produce the kind of post-purchase experience that a luxury jewelry brand cannot afford to generate at any scale.
Proprietary diamond cuts with exclusive distribution rights and cultural collection lines built around Chinese heritage traditions require content that most e-commerce templates cannot provide. A 100-facet diamond cut developed with one of the world’s foremost master cutters needs content communicating its distinction to an international buyer with no reference point for what makes it different from a standard brilliant cut. A cultural collection built on Chinese aesthetic traditions needs content that translates those traditions meaningfully for a fine jewelry audience encountering them for the first time.
Our Solution
Keyideas built Chow Tai Seng’s international store on Shopify with a catalog supporting over 10,000 GIA-certified loose diamonds and real-time one-hour reservation locks preventing two buyers from completing checkout on the same stone simultaneously. Multi-currency checkout was configured across all target international markets with payment method availability adapting per region, removing the friction that causes international luxury buyers to abandon at the payment step. The Shopify architecture gave the brand the platform foundation to serve international buyers at scale without the limitations of a domestically focused system.
The LOVE100 diamond, a 100-facet cut developed with master cutter Gabi Tolkowsky in 2013 with exclusive Greater China distribution rights, and the Constellation Aurora second-generation cut launched in 2017, each received dedicated landing pages explaining their cutting methodologies and technical distinctions in a format accessible to international buyers with no prior knowledge of either cut. These pages positioned the proprietary cuts as genuine luxury innovation rather than unfamiliar brand terminology, giving the brand a credible differentiator against Western luxury houses on the international buyer’s first encounter with the catalog.
The Happy Flower Marriage bridal collection and the Forbidden City cultural collaboration were built as campaign hubs with collection storytelling, individual product galleries, and filtering by jewelry type and metal, giving Chow Tai Seng the ability to launch collection campaigns for international markets without rebuilding the page structure for each new cultural release. Each hub was designed to make the cultural significance of the collection accessible and compelling to buyers outside China, connecting the brand’s heritage to an international fine jewelry audience that responds to craft narrative and design provenance.
A four-stage diamond customisation workflow guides international buyers from stone selection through setting choice, personalisation specifications, and either appointment booking at a nearby experience store or remote workflow confirmation for buyers without local access. A QR code desktop-to-store flow was integrated for buyers who prefer to begin their purchase online and complete it in person at a Chow Tai Seng location. The international brand story was built to establish the brand’s 25-year heritage, Deloitte Global Luxury ranking, and Shenzhen listing as peer-level luxury credentials for new international buyers.
