Royal Blue Sapphire 35cts
The Blue Sapphire is one of the most alluring of the Sapphires found in Sri Lanka. It is the next hardest mineral to the Diamond on Mohs scale of hardness. The Diamond ranks at 10 and Sapphire at 9. It is in the gem variety know as Corundum derived from the Sri Lankan name "kuruvinda" which is a place of gem mining for centuries in Ceylon & now named as Kuruwita.
The Mineral composition of Sapphire is Al2O3 + Fe + Ti ( Aluminum Oxide).
The Iron ( Fe) and Titanium (Ti) is what make the Sapphire Blue, and in special instances with Vanadium it turns violet under incandescent ( spot) light giving it a colour changing effect, blue in day light and violet in spot light.
All these occurrences take place naturally over millions of years while in the ground.
The best hues in the Blue Sapphires are a fiery cornflower blue that have an electric luster or a rich royal blue with its mesmerizing deep rich colour and liquid like luster. It is a true gift of God!!
Many say the the Blue Sapphire is aptly named as "The King" of gemstones, which I too would agree without contest.
