4.5 Ct Royal Blue Heated Sapphire — Sri Lanka

At 4.5 carats, this sapphire is cut as a well-proportioned oval and shows a rich royal blue — deep, saturated, and leaning slightly toward violet in certain light, the color most people picture when they hear the word 'sapphire.' The stone has undergone standard heat treatment, the same time-honored process used on the majority of fine sapphire in the trade, which intensifies color and improves clarity while leaving the gem 100% natural corundum.

Sourced from Sri Lanka, one of the world's oldest and most prolific sapphire-producing regions, this stone offers the classic royal blue look at a more accessible price point than comparable unheated material — a practical choice for anyone who wants the look of a fine sapphire without the premium that no-heat stones command.

Sapphire ranks 9 on the Mohs scale, making it exceptionally hard and scratch-resistant, well suited to rings worn every day as well as earrings and pendants.

• Type: Natural Sapphire

• Treatment: Heated

• Weight: 4.5 Cts.

• Color: Royal Blue

• Shape/Cut: Oval

• Origin: Sri Lanka
