Gemologically, there is a significant difference between Mozambique rubies and Myanmar rubies (Burmese Ruby or Burma Ruby).
In terms of color, Rubies from Burma are characterised by their vivid red or deep blood red hue. However, certain low-quality stones display pinkish red hue as well. Too dark red Burmese ruby are extremely rare.
On the other hand, the color of Mozambique ruby in deeper shades are comparatively easier to find. Due to the presence of iron traces, certain ruby pieces from Mozambique appear deep purplish red in color. As the color shifts towards darker side, the quality of Mozambique ruby drops significantly. Mozambique ruby of the finest quality also bears deep Pigeon Blood Red hue, but it is less common in nature.
Now, clarity is another important factor to differentiate these two ruby stone varieties. Rubies from Burma are fairly included gemstones that contain both highly visible and less inclusions. Eye clean Burmese ruby are exceptionally rare in nature. Mozambique rubies contain silk (rutile needle like inclusions), which are not visible to the naked eyes but hamper their transparency and crystal-like appearance.
