Most Popular Blue Gemstones
1. Sapphire (Neelam)
Blue sapphires are among the most renowned blue gemstones, celebrated for their rich color and durability. Historically associated with royalty and wisdom, the term "sapphire" comes from the Latin "sapphirus" and Greek "sappheiros," meaning blue. These stones have been treasured since ancient times for their protective qualities.
Blue sapphires owe their color to iron and titanium in the corundum mineral. The most prized shades are vivid, velvety blues. While sapphires can appear in other colors, blue remains the most popular and valuable. Major sources include Sri Lanka (Ceylon), known for its cornflower blue sapphires, and Madagascar, offering a range of sapphire colors and qualities.
In addition to their aesthetic and historical significance, blue sapphires hold a special place as the birthstone for September. They are believed to bring protection, wisdom, and serenity to those born in this month.
