Buying a loose gemstone gives you independence, you get the freedom to make your own choice, your own jewelry design.
A natural 1.55 carat blue sapphire in a cushion cut, from Sri Lanka (Ceylon), heat treated. Ceylon cushion blue sapphire is the most historically resonant format in sapphire jewelry — the Princess of Wales ring that brought sapphire into global engagement ring consciousness was a 12-carat Ceylon cushion blue, and the shape has defined the category ever since. At 1.55 carats, this stone sits in the practical center stone range for engagement rings, with the cushion geometry deepening the Ceylon blue saturation across the face.
Why Choose this 1.55 ct Cushion Ceylon Blue Sapphire?
The cushion cut concentrates blue saturation more effectively than oval or round alternatives of the same carat weight — the rounded corners trap light and deepen the color, producing the glowing, rich blue that defines the finest cushion sapphires. Ceylon origin ensures the color profile that most people mean when they say blue sapphire. At 1.55 carats, this is the format and size that most consistently meets the expectations of blue sapphire engagement ring buyers.
