All You Need to Know About Sapphires

 

PHYSICAL AND OPTICAL PROPERTIES OF Sapphire

Sapphire, like ruby, is a variety of corundum. This mineral is an aluminum oxide of Al2 O3 chemical composition. Sapphire can be in many colors depending on the coloring elements it contains iron and titanium for blue stones, iron for yellow and green, vanadium for violets, chrome for pink …

Its crystalline system is trigonal. Its hardness is very high: 9 on the Mohs scale which comprises ten grades, the highest of which corresponds to diamonds. It has a density of 3.95 to 4.03, its brightness is glassy, ​​and its pleochroism is strong. Some sapphires have no luminescence, others have an apricot color.

THE COLORS OF SAPPHIRE

All varieties of corundum that are not red are placed in the sapphire category, including leuco-sapphire, colorless, and padparadscha, an incredible hue between pink and orange: its name comes from a word Sanskrit meaning lotus flower…

Blue sapphire is the best known. Light blue, blue-gray, dark blue, all shades are possible. Royal Blue and Cornflower Blue have a deep hue and are very popular.

Pink sapphire goes from pastel to bright pink, and the most valuable ones are the ones that shoot the least to purple.

The yellow sapphire is not the most sought after because it is often less brilliant and clear than the others.
Green sapphires are also not popular; their color is less beautiful than other green gems.

Orange sapphires are very rare, and you have to be careful: most of the ones on the market are tinted stones unless you have an adequate certificate.

The sapphires of a bright purple are very popular because they are rare, especially in large dimensions.

MAIN DEPOSITS OF SAPPHIRES

Sapphire is formed either in magmatic rocks or in the frontier zones between pegmatites (main constituents of the Earth’s mantle) and adjacent rocks, and finally in metamorphic rocks such as gneiss and mica schists. Sapphires can be found in the alluvium, having resisted the erosion of the rocks which sheltered them.

Sapphire is more common than its twin ruby. They are found all over the world, for example in Australia, Brazil, Madagascar. The most important deposits and those containing the most beautiful stones are generally in Asia: the mines of Kashmir, in India, in Sri Lanka where cornflower (blueberry color) is produced, in the mines of Mogok in Burma…

THE ADVICE OF OUR GEMOLOGIST: HOW TO CHOOSE SAPPHIRE?

To choose your sapphire, you have to be attentive to several criteria:

  • The color: the sapphire must be a beautiful deep blue and deep, without being too dark because it would reduce its transparency. You should also know that sapphires lose some of their glow under an incandescent lamp, while they reveal all their brilliance in the light of the sun.
  • Transparency: sapphires generally have fewer inclusions than rubies. It is better to prefer a stone for greater clarity, even if a light veil, called “silk”, can have its charm.
  • Size: it is difficult because the raw sapphire is rarely homogeneous. The lapidary must, therefore, decide in which part he will cut the gem so that it is the most beautiful. The oval cut or the cushion size reveal all the sparkle of the sapphire, but we also find hearts, pears, circles…

Sapphires are often heated to 1300 degrees to intensify their color and reduce the visibility of inclusions.
