Yes, blue sapphires can sparkle, but the degree of sparkle depends on several factors including cut, clarity, and tone.
Here's a breakdown:
-
Cut: A well-cut sapphire will maximize light reflection, creating more brilliance and sparkle. If the sapphire is cut poorly, light will escape from the bottom or sides, making it appear dull.
-
Clarity: Sapphires with fewer inclusions (internal flaws) allow more light to pass through, resulting in a more vibrant sparkle. Sapphires with numerous or large inclusions will scatter light, diminishing their sparkle. "Eye clean" sapphires (those without visible inclusions to the naked eye) tend to sparkle the most.
-
Tone (Color Darkness): Medium to light-toned blue sapphires tend to sparkle more than very dark ones. Darker sapphires absorb more light, reducing the amount that can be reflected back to the viewer. Lighter tones allow for greater light reflection.
In summary, a blue sapphire with a medium to light tone, high clarity (ideally eye clean), and an excellent cut is more likely to exhibit a beautiful sparkle. Darker stones, those with significant inclusions, or those that are poorly cut will not sparkle as brightly.
