VIETNAMESE RUBY
When Vietnamese rubies first appeared on the market in late 1990s, the trade was surprised by their vivid colour and exceptional crystalline clarity that can even rival those from Mogok in appearance. Vietnamese rubies usually have a glow in the red colour and are of lively brilliance. The country which had never previously been known for any gemstone sources thus was believed by many experts that produced one of the two finest ruby mines in the world.

The majority size of Vietnamese rubies is less than 2 carats. Most Vietnamese rubies have naturally excellent clarity and are exempted from treatment; nevertheless, since many stones tend to be pinkish, heating is still commonly applied to the less saturated goods. Therefore, a natural untreated Vietnamese ruby of fine quality is very rare; let alone a special stone over 5 carats.
