Zaffiro: la storia e i segreti della pietra blu per eccellenza

Sapphire: the history and secrets of the blue stone par excellence


Sapphires are a variety of Corundum, and Corundum is technically colorless: minimal traces of elements foreign to the basic chemical formula are enough for it to take on even vivid colors. The best-known color is blue and the rarest is the “Padparadscha” (pinkish-orange). The term sapphire designates the blue variety and ruby the red one, but pink, light blue, yellow, green, etc., are referred to as blue, yellow, green, etc. corundum. There are many colors of corundum in nature.

Sapphire color: how much and how it affects value

The color itself is the most important factor in defining the price and value of a sapphire, in addition to clarity, brilliance, and size. In general, sapphires that are too dark or too light have a lower value: the color must be intense and lustrous. Some microscopic inclusions called “silk” can give sapphires a velvety or soft appearance that accentuates their beauty. In cases where the inclusions are oriented in a particular way, the phenomenon of asterism occurs: a six-rayed star appears inside the gem as a luminous reflection. The most famous star gem is the 563.4 ct “Star of India” mined in Sri Lanka: found about 300 years ago, it is now kept at the American Museum of Natural History in New York.

Kashmir sapphires: the most precious in the world

Kashmir, India 1881: a tremendous avalanche in the Himalayan peaks brings to light, at an altitude of 4,000–5,000 meters, a sapphire mine. They are gems of the purest blue, which shine the same way under any light, including artificial light. Once the treasure was discovered, the Maharaja of Jammu and Kashmir, Ranbir Singh, immediately took control of the area and the mine, declaring himself the owner of the excavations. After 40 years, the Maharaja's mines were exhausted, which helped to increase the myth of the sapphires that were extracted there. Sapphires from Kashmir are considered the most beautiful in the world: they display a vivid, velvety blue hue that is unique to the region and are among the most prized gems for their rarity and scarcity. From time to time they still appear on the market as collector's items or mounted in antique jewelry. They certainly set a benchmark against which all other sapphires are measured and are highly sought after.

 

 

 

Sapphire: meaning, history, and symbolism of the blue stone

Like many famous gems, the blue sapphire appears in religious and mythological tales of antiquity and symbolizes sincerity and serenity. It is often used as a talisman to preserve purity and protect the wearer. It is highly sought after for its "gifts" of psychic activation and spiritual quest: its color (from the Greek “Sappheiros”, blue) brings order and healing to the mind, bestowing strength and focus, and the ability to see beyond superficial appearances. It is an exceptional gem for calming the mind and encourages intuition, bringing with it lightness, joy, and balance. As an engagement ring, it represents “faithful love” and certainly “the most beautiful thing,” according to the ancient Hebrew “Sappire”.
