Mentioning Vietnamese stars' diamond hobby, Ly Nha Ky is the most prominent name. The actress has repeatedly attracted attention when appearing on the red carpet of the Cannes Film Festival with jewelry sets believed to be worth tens of billions of dong.
In April 2023, Ly Nha Ky said that she wore a set of diamond jewelry from an Italian brand worth about 20 billion VND when attending a fashion show in Ho Chi Minh City.
At an event in March 2025, Ly Nha Ky's crew said she used a set of diamond-studded necklaces, rings and earrings worth about 20 billion VND.
Ly Nha Ky especially attracted attention in her appearances at the Cannes Film Festival. In 2022, she wore a set of jewelry including a 180,000 USD necklace, 55,000 USD earrings and a 32,000 USD ring, equivalent to more than 6 billion VND at that time's exchange rate.
More notably is the collection of rare colored diamonds that Ly Nha Ky has publicly announced in recent years. She once introduced a purple diamond valued at about 22 million USD (more than 550 billion VND) and a fancy Vivid Blue diamond valued at about 35 million USD (nearly 900 billion VND).
If Ly Nha Ky stands out with rare diamonds, Ngoc Trinh attracts attention with her hobby of collecting large diamond rings. In 2021, the beauty once offered to sell a 13-mm diamond ring for 7.9 billion VND, while revealing the initial purchase price of about 14 billion VND. In addition to this ring, she also owns many necklaces, earrings and diamond jewelry worth billions of VND.
Le Quyen is also considered one of the beauties with a special passion for diamonds. On social networks as well as at events, the female singer often appears with large diamond rings, many models are estimated by jewelry businesses to be worth from several billion VND.
However, Le Quyen rarely announces the specific value of each item, instead saying that she loves diamonds because of their durability and preservation value over time.
Meanwhile, Tran Thanh does not collect diamonds in the traditional sense but mainly owns diamond-studded watch models. The male MC used to use a Patek Philippe Nautilus 5724G watch with diamond-studded bezels, the international price ranged from about 130,000-150,000 USD, equivalent to 3.3-3.8 billion VND, even at times in the secondary market exceeding 200,000 USD (about 5 billion VND). In addition, he also owns many watch models from Audemars Piguet, Rolex or Hublot priced from billions of VND.
Another face is Dam Vinh Hung, who has been pursuing a luxurious style for many years with large diamond rings, watches and gemstone-studded accessories.
