Buying a loose gemstone gives you independence, you get the freedom to make your own choice, your own jewelry design.
A natural 1.58 carat pale blue sapphire in a round cut, completely unheated. Pale blue sapphire is the light-tone end of the blue corundum range — a color with lower saturation that reads with a soft, airy quality rather than the rich depth of royal or cornflower blue. At 1.58 carats in a round cut, this stone has the weight for a center stone in delicate engagement ring designs and pendants where a soft blue creates a romantic rather than dramatic aesthetic. Unheated status preserves the natural tone exactly as formed.
Why Choose this 1.58 ct Unheated Round Pale Blue Sapphire?
Pale blue sapphire appeals to buyers who want the blue sapphire tradition in a softer, lighter register than the vivid saturated blues that dominate the engagement market. The tone reads with more subtlety — closer to aquamarine in feel, but in the hardness and durability of Mohs 9 corundum. At 1.58 carats, the round cut gives this stone sufficient face-up surface to display the pale blue at wearing distance, and unheated status confirms the natural tone.
