In the world of porcelain collecting, many people often think of ancient pieces from the Ming and Qing dynasties. However, in recent years, contemporary porcelain—once overlooked—has begun to gain attention as its value steadily rises. Investors are now turning their focus toward this emerging market, which is seen as having significant potential for appreciation. According to industry experts, certain high-quality contemporary works, with reasonable pricing and exceptional craftsmanship, are not only worth collecting but also hold great promise for future growth.
Ceramics have always been a highly valued collectible, and in recent years, the prices of master-class contemporary ceramic artworks have shown steady increases. Jingdezhen porcelain, in particular, has experienced some of the most dramatic price hikes. It is reported that the average increase for works by renowned Jingdezhen ceramic artists over the past few years has ranged between 20% and 30%. For instance, a piece by the celebrated ceramic artist Lu Ru, which once sold for under 100,000 yuan in 2006, is now valued at over 500,000 yuan. Similarly, a teapot created by the master craftsman Dai Ronghua saw its price rise from around 50,000 yuan in 2007 to more than 200,000 yuan today. With the market becoming increasingly rare, expensive, and saturated with fakes, many collectors are shifting their attention to contemporary porcelain.
Anonymous collector Liang Wei shared his perspective, stating, “Investing in porcelain requires foresight. Waiting for prices to go up is too late.†Over the past few years, he has started investing in contemporary porcelain, finding it more accessible compared to ancient pieces, which are often prohibitively expensive. Industry insiders note that contemporary porcelain is more closely connected to the historical pieces on the market. Additionally, the high cost of ancient porcelain makes it difficult to verify authenticity. In contrast, the artistic value of contemporary masterpieces tends to grow alongside the creator’s experience, gaining wider recognition. With fewer imitations and easier identification of origin and maker, contemporary porcelain offers a more transparent investment option.
Ma Huiyi, a senior appraiser at the Tongbao Chongqing Branch for ancient and modern artifacts, suggests that those interested in investing in contemporary porcelain should start by focusing on three key categories. First, look for popular works by top contemporary craftsmen, especially national first-class arts and crafts masters or provincial-level master artisans. Second, consider pieces that reflect the cultural and historical significance of different periods, such as Great Yuejin porcelain or Cultural Revolution-era ceramics. Third, focus on antique art porcelain produced by the former Ministry of Light Industry's Jingdezhen Art Porcelain Factory. These pieces are known for their quality, affordability, and strong potential for appreciation, making them ideal for new collectors.
However, Ma Huiyi also cautions that not all contemporary porcelain holds value. When selecting pieces, collectors should pay attention to the form, color, and design of the work. It is best to choose smaller, decorative items like ornaments or daily-use porcelain, as large-scale collections may not offer the same return. Moreover, since contemporary ceramic art is mass-produced, investment risks have increased. Therefore, it's essential to evaluate the artist’s reputation, skill, and creative vision before making a purchase.
