This Blue Sapphire weighs approximately 2.45 carats and is certified by the Antwerp Laboratory for Gemstone Testing (ALGT), ensuring its quality and authenticity.

As a variety of corundum, sapphires have a remarkable hardness of 9 on the Mohs scale, ranking them among the hardest natural gemstones, which makes them perfect for daily wear in jewelry. Their color is generally due to trace impurities of iron and titanium within the crystal structure. The Antwerp Laboratory certification is a respected documentation that details the gem’s characteristics such as color, clarity, and cut, providing confidence and transparency for buyers and collectors. Historically, blue sapphires have been associated with nobility and wisdom and remain a popular choice for engagement rings and heirloom jewelry. Their combination of beauty, durability, and symbolic meaning has sustained their timeless appeal in the gem market.
