This article highlights the launch of a global subscription channel for rare, large-carat diamonds by Zheguang Diamond. The featured collection includes high-grade white diamonds and scarce fancy color stones, many of which are seldom available in the Chinese market.

In late November, Zheguang Diamond (ZG DIAMOND) announced the launch of a global subscription channel for a limited number of large-carat fancy color diamonds. The collection features a formidable lineup, encompassing white diamonds ranging from 5 to 32 carats, as well as extremely scarce fancy color diamond categories such as pink, yellow, and blue diamonds. Many of these are high-custom-grade treasures rarely seen in circulation within China.
Among the numerous pieces, a rare 32-carat pink diamond has become the focal point. In the international auction market, fancy color diamonds of similar size often command prices exceeding tens of millions of yuan, while the number of publicly circulating pieces of comparable specifications within China is fewer than five. In addition, the collection includes exquisite individual pieces such as a 16-carat orange-pink “pigeon egg,” a 10.1-carat “sugar cube” blue diamond, an 8.7-carat pear-shaped yellow diamond, a 14-carat yellow diamond ring, and an 11-carat pink diamond necklace for formal occasions. All these pieces have been securely stored by Zheguang in dedicated safes for an extended period. They boast exceptional 4C standards, with clarity uniformly reaching VVS grade, color grades between D and F, and cut graded as 3EX. Their quality is sufficient to rival pieces found at top-tier international auctions.
The Zheguang brand revealed that these large-carat fancy color diamonds have long been core reserves for its high-customization business and are being offered for subscription to the market for the first time. The subscription is open to a wide range of clients, including global diamond collectors, high-end custom wedding ring customers, and luxury institutions. Large-carat pieces that were previously hard to find on the market, such as 5-carat “pigeon eggs” and 20-carat “royal style” diamonds, can now be directly matched with end-user demand through this subscription channel. After selecting their desired piece, clients can also enjoy Zheguang’s 1-on-1 high-customization design service to have the loose diamond crafted into exclusive jewelry.
As “China’s premier high-customization diamond brand,” Zheguang leverages the advantages of the diamond industry chain in Zhecheng, Henan, and ranks among the top domestic brands in terms of reserves of large-carat rare fancy color diamonds. This subscription offering not only releases core scarce assets but also marks a significant step for a Chinese high-customization diamond brand into the global circulation of high-end diamonds. Currently, Zheguang has opened a global dedicated consultant liaison channel. All pieces are offered through a limited “one-diamond, one-negotiation” subscription mechanism. Specific quotas and cooperation details require contacting the official website or online e-commerce dedicated consultants to complete qualification verification.
