Different Types of Ruby Gemstones
Certainly, Rubies can exhibit a range of red hues with remarkable luster and saturation. Ruby is among the most precious gemstones and belongs to the Corundum mineral family (aluminum oxide). The color of Rubies can vary from red, dark red, blood red to reddish-pink, and even pigeon blood-red. This coloration is due to the presence of chromium in the stone. Besides the color, saturation, and tone of Ruby, it can be classified further based on its shape and origin, which includes Burmese, Thai, Tanzania, Madagascar, and Africa. These variations of Ruby can possess significant differences among them.
Stones from India: Ruby has
been highly valued in India for a long time. Prior to the 20th century,
Ruby was considered more valuable than even diamonds. Indian Rubies are
predominantly found in Orissa and Mysore and feature unique cuts and
colors. These are commonly used in silver and fashion jewelry due to their
exquisite aesthetic appeal.
- Deep Red Ruby: The most commonly known type of Ruby stone features a rich blood-red color with excellent saturation and luster. The color of a natural Ruby stone has the most significant impact on its overall value, with well-balanced, dark red, and consistent hues being the most desirable.

Rubies from Old Burma are flawless and can be worth millions of dollars, and their unique markings help to identify them as being from Old Burma.

The Burma Star Ruby is the most valuable due to its brilliant red hue and distinct star effect, while Star Ruby from Sri Lanka and India are other important varieties that are highly valued after Burmese Ruby stones.
- Pigeon’s Blood Ruby: The Pigeon’s Blood Ruby gets its name from the bright red hue with a hint of purple, reminiscent of the color of freshly killed pigeons.

While some stones may display blue color-zoning, the area is also known to produce top-quality, perfectly red, and very clear Manik stones.
