1. Famous gemstones from Luc Yen
Luc Yen gemstones have long been renowned not only in Vietnam but also in international markets thanks to their natural beauty, diverse colors, and exceptional quality. Among them, Luc Yen ruby holds the crown as the "king" of gemstones, while Luc Yen sapphire impresses with its vibrant color variations. In addition, other valuable stones such as spinel and tourmaline contribute to the rich diversity of this gemstone haven. Each type of stone possesses its unique charm, establishing the reputation of Luc Yen gemstones as a true national treasure admired both locally and globally.
1.1. Luc Yen Ruby – The king of gemstones
Luc Yen ruby is highly prized among gemstone connoisseurs and is often compared to Myanmar ruby due to its intense fiery red color, high clarity, and strong fluorescence. Particularly rare are stones with a pinkish-red or vivid "pigeon blood" hue. Premium-quality rubies over 3 carats with high transparency and minimal inclusions can fetch hundreds of thousands of dollars per piece. These exquisite stones are commonly used in luxury rings, pendant necklaces, or even held as valuable gemstone investments.
1.2. Luc Yen Sapphire – Nature’s spectrum of color
Beyond ruby, Luc Yen sapphire is one of the most sought-after gems thanks to its deep blue, green, and rare yellow-orange hues. These sapphires boast a Mohs hardness of 9, excellent clarity, and sometimes exhibit the valuable star effect (asterism). Deep blue sapphires are the most popular, while the extremely rare padparadscha sapphire – a delicate mix of pink and orange – commands high value. Luc Yen sapphires are frequently used in high-end jewelry, feng shui applications, and gemstone collections.
1.3. Spinel, Tourmaline, and other gemstones
In addition to ruby and sapphire, Luc Yen is also rich in other precious and semi-precious stones:
Luc Yen spinel comes in shades of red, pink, or purple and is often mistaken for ruby, though it is generally more affordable. Bright red spinel remains a popular choice for fine jewelry.
Luc Yen tourmaline features a wide color range from green and pink to multicolor varieties like watermelon tourmaline. These are commonly used in feng shui bracelets or statement rings.
Other stones such as amethyst, garnet, and topaz are also mined here, typically serving as more accessible options for fashion jewelry or spiritual items.
This exceptional diversity and natural richness have solidified the status of Luc Yen gemstones as a true natural treasure — where every stone captures the spirit of the Vietnamese land, the harmony of nature, and the artistry of local hands.

Luc Yen gemstones have long been highly regarded by international collectors for their outstanding quality standards. With vibrant colors, exceptional clarity, and ideal hardness, each gemstone from this mountainous region in Yen Bai province carries the hallmarks of a natural treasure.
Luc Yen rubies are particularly prized for their vivid red color—sometimes reaching the rare and coveted “pigeon blood” hue, a hallmark of the highest-grade rubies worldwide. Many of these gems exhibit remarkable transparency, minimal inclusions, and strong fluorescence under light, creating a luxurious and captivating visual effect. In terms of hardness, Luc Yen’s rubies and sapphires score 9 out of 10 on the Mohs scale—on par with the world's top gemstones.
When compared to renowned mining regions like Mogok (Myanmar), Ratnapura (Sri Lanka), or Kashmir (India), Luc Yen gemstones are still highly valued by international gemologists for their potential and quality. Many Luc Yen rubies and sapphires meet export standards for demanding markets such as the U.S., Japan, and Europe. Some large, high-clarity, vividly colored stones can fetch prices in the tens or even hundreds of thousands of dollars—rivaling similar gems from globally established sources.
Comparative value:
Luc Yen Ruby vs. Myanmar Ruby:
Luc Yen rubies possess a vivid red tone comparable to the world-renowned Myanmar rubies, yet are priced 20–30% lower due to lesser brand recognition. However, Luc Yen rubies are praised for their strong fluorescence and high clarity, earning them the title of Asia’s “hidden gem.”
Luc Yen Sapphire vs. Sri Lankan/Kashmir Sapphire:
Luc Yen’s blue sapphires match the quality of Sri Lankan stones, though their price is typically 50–70% lower due to a more stable supply. Rare sapphire varieties from Luc Yen, such as padparadscha (pink-orange), can command prices between $5,000 and $10,000 per carat—on par with elite international stones.
Luc Yen Spinel & Tourmaline:
Red spinels from Luc Yen are about one-third the price of Myanmar spinels, despite offering similar quality. Meanwhile, Luc Yen's multicolor tourmalines are increasingly popular for their affordability—ranging from $200 to $500 per carat—compared to those from Brazil or Africa.
These exceptional qualities and competitive values have helped Luc Yen Gemstones secure a place on the global gemstone map, affirming Vietnam's reputation as a country blessed with rare and remarkable mineral resources.
