Buying a loose gemstone gives you independence, you get the freedom to make your own choice, your own jewelry design.
A natural 1.03 carat color-change sapphire in an oval cut, from Sri Lanka (Ceylon), completely unheated. Color-change sapphires shift hue between lighting environments — this stone displays a distinctly different color under daylight versus incandescent light, a phenomenon caused by trace vanadium in the crystal that absorbs different wavelengths under different spectral distributions. At just over 1 carat from Ceylon, unheated, this is a well-specified example of one of the most unusual optical phenomena in natural gemstones.
Why Choose this 1.03 ct Unheated Ceylon Color-Change Sapphire?
Color-change sapphire in unheated quality above 1 carat from Ceylon is uncommon — the combination of the phenomenon, the treatment status, and the origin in a single stone represents a meaningful convergence of collectible attributes. The oval cut at this weight is the most practical format for showing the color shift in both earring/pendant and ring settings.
