Michelle Ong — Carnet's Founder and the Hong Kong High-Jewellery Vision
Sculptural one-of-a-kind pieces blending Asian aesthetics with European haute joaillerie technique
Michelle Ong is the Hong Kong-based haute joaillerie designer and founder of Carnet, the high-jewellery house that has established itself as one of the most distinctive Asian voices in contemporary international fine jewellery. Working from her Hong Kong atelier since the founding of Carnet in 1998, Ong has developed an idiom that combines sculptural three-dimensional forms with bold use of colour, exceptional gemstone selection, and the synthesis of Asian aesthetic sensibility with European high-jewellery construction technique. Her work has been exhibited at Masterpiece London and other major international fairs, has been collected by the leading Asian and global collectors of contemporary haute joaillerie, and has commanded six- and seven-figure prices through both private commission and major auction sales.
Background and the founding of Carnet
Ong's background combines training in international design and business with the deep gemmological and craft knowledge that the Hong Kong jewellery trade tradition supports. Hong Kong's position as one of the world's principal centres of coloured-stone trading — with extensive dealer infrastructure connecting the Asian markets to Burmese ruby, Kashmir sapphire, Colombian emerald, and the broader fine coloured-stone supply — provides direct access to exceptional gemstones that supports the high-jewellery design practice. Her early career in the Hong Kong trade gave her the foundation in stone selection and design that her later independent practice has built upon.
Carnet was founded in 1998 with the explicit positioning as a high-jewellery house producing one-of-a-kind pieces rather than commercial collections. The atelier model — with master craftsmen working under Ong's design direction to produce small numbers of major pieces each year — allows the level of individual attention to design and execution that distinguishes haute joaillerie from commercial fine-jewellery production. The house's name, French for "notebook" or "sketchpad," suggests both the design-driven nature of the practice and its connection to the European haute joaillerie tradition.
The design idiom
Carnet pieces are characterised by several distinctive elements. The use of colour is deliberately bold, with strong combinations of saturated coloured stones — Burmese rubies, Kashmir sapphires, Colombian emeralds, and rare coloured diamonds — set in compositions that exploit the visual contrast between the colours rather than the more restrained palettes typical of Western traditional haute joaillerie. The asymmetric compositions favoured by Ong distinguish her work from the more symmetrical conventions of European maison design.
The Asian aesthetic sensibility in her work draws on multiple sources including Chinese classical art (the painting tradition's interest in asymmetric composition and natural-form motifs), Japanese decorative arts (the asymmetric balance and economy of form in the major Japanese craft traditions), and the broader contemporary Asian design culture. The integration of these sources with European high-jewellery construction technique — the lost-wax casting, the precise stone-setting, the gold and platinum metalwork — produces work that is recognisably contemporary and Asian without being limited to any specific traditional reference.
Subject matter often draws on natural forms, with floral, foliate, and animal motifs translated into sculptural three-dimensional compositions. The technical challenges of constructing these forms in precious metal with stone-setting at the level Ong demands have driven Carnet's investment in technical capability, with the atelier developing the construction methods needed to realise the design vision.
Stone selection and gemstone significance
Carnet pieces are notable for the quality and significance of the gemstones used. The Hong Kong trade location provides access to fine Burmese rubies (the historic benchmark for the species), Kashmir sapphires (the rarest and most valued sapphire origin), Colombian emeralds, and the broader range of fine coloured stones that supply the upper register of the international market. Carnet pieces frequently incorporate stones with documented major laboratory certification — Gübelin, SSEF, GIA, AGL — that supports both the authentication and the commercial value of the finished pieces.
Rare coloured diamonds — pink, blue, fancy yellow, and the rarer green and orange diamonds — also feature in Carnet work, with the Hong Kong access to the major coloured diamond auction sales supporting the acquisition of significant stones. The use of fancy coloured diamonds in combination with traditional and rare coloured stones is one of the distinctive features of Carnet's design vocabulary.
The international exhibition and auction record
Carnet pieces have appeared at major international high-jewellery exhibitions and have achieved significant prices at auction. Masterpiece London — the annual fine art and jewellery fair that has hosted exhibitions of major contemporary haute joaillerie designers — has featured Carnet work in multiple years. Major Christie's, Sotheby's, and Bonhams auctions have included Carnet pieces, with the auction record contributing to the broader documentation of the house's market position.
The international exhibition presence supports the recognition of Carnet beyond the immediate Hong Kong and Asian collector base, with European, American, and Middle Eastern collectors increasingly representing significant components of the Carnet collector community. The independent designer position requires sustained outreach to maintain and develop the international collector base, and Carnet's exhibition and auction strategy has supported this outreach effectively over the past two decades.
The Asian high-jewellery context
Ong and Carnet operate within the broader contemporary Asian high-jewellery context that includes Wallace Chan (the Hong Kong designer whose innovative technical work has set new standards in contemporary haute joaillerie), Cindy Chao (Taipei-based with international atelier presence), and the smaller cohort of contemporary Asian high-jewellery designers operating at the apex of the international market. The Asian designers collectively represent the most significant contemporary alternative to the European maison-dominated high-jewellery establishment, with each designer bringing distinct stylistic identity and individual artistic vision to the broader category.
The Asian collector base — particularly the Hong Kong, Singapore, Taiwan, and broader Greater China collector communities — has grown substantially in scale and sophistication over the past several decades, providing the demand context that supports the contemporary Asian high-jewellery design community. The Western collector base has also become increasingly receptive to Asian designers' work, with the broader internationalisation of the high-jewellery market reducing the historical dominance of European houses.
For the trade
For the international high-jewellery trade, Michelle Ong and Carnet represent one of the principal references for contemporary Asian high-jewellery design at the apex of the market. Dealers, auction specialists, and collectors recognise Carnet pieces by their distinctive idiom — the bold colour, the sculptural form, the asymmetric composition, the exceptional stone selection — and the house's market position has become well established over its more than two decades of practice.
