Kashmir Legend
Although some Burmese and Ceylonese sapphires are famous, only the Kashmir Sapphire could be named as “King of the Sapphire World”.
Kashmir is located in the northwestern corner of the Indian subcontinent, in a valley between India and Pakistan. With an average altitude of over four thousand meters, Kashmir is cold all year round. The mining work is hard in Kashmir due to short annual production time and frequent wars. These make the gem hard to come by.
Since the mines were depleted such a short of time, the scarcity of Kashmir sapphires has made these stones tremendously sought-after by gem connoisseur all around the world.
Kashmir sapphires pronouncedly display distinct blue colour and the signature ‘velvety’ texture caused by the inclusion of silk. With the source is non-existent, these Kashmir sapphire are almost never seen except in the auction market. Most of the Kashmir sapphires that exist in auction market were discovered more than 100 years ago. As these superlative sapphires are unrivalled among sapphires around the world, the demand for the gem far exceeds the supply.

Bulgari
Bulgari’s history can be tracked back to 1884 when Sotirio Georgis Bulgari opened his silverware shop in Rome, paying meticulous attention to producing pieces with unparalleled craftsmanship and creativity. In 1930, his two sons Costantino and Giorgio expanded the family business to include jewellery in Via Condotti, building a reputation its internationally renowned range of high jewellery.
For more than 130 years, Bulgari has developed a unique brand style. During the early 20th century, diamond-centric jewellery was most popular. However, deviated from the traditional Parisian school of jewellery, Bulgari started exploring the use of coloured gemstones, making jewellery pieces that come alive in a rainbow of colour combinations. It also reintroduced the cabochon cut for gemstones, transforming the jewellery industry profoundly.
