The Royal Family is known for their beautiful colored gemstones and Princess Eugenie (daughter of Sarah, Duchess of York) is the latest to make news with her ring. Boyfriend Jack Brooksbank proposed with a rare sapphire and diamond engagement ring.
The center stone is an oval-shaped pinkish orange padparadscha gemstone, which is one of the rarest of all sapphires and typically originate in Sri Lanka but are also found in Madagascar and Tanzania. The sapphire is surrounded by a halo of small diamonds and the mounting is a vintage-style design in yellow and white gold.
Padparadscha is a derived from a Sinhalese word for “aquatic lotus blossom” with a beautiful salmon color. The color for the padparadscha sapphire can range from a salmon color with a pinkish hue to an orange hue. It is difficult to find a padparadscha over two carats in weight. When one is found it is considered exceptional and extremely rare.
Padparadscha sapphires from Madagascar are at times heat treated to intensify their pink coloration. They are heat treated at very low heat temperatures, whereas padparadscha stones from Sri Lanka will be heat-treated at higher heat temperatures when heat-treated. The heat-treated padparadscha stones from Madagascar are often recommended over the ones from Sri Lanka because of the temperature they are treated at.
