4.99 Ct. Color Change Sapphire from Ceylon (Sri Lanka)

There are gemstones, and then there is this singular color change sapphire, a treasure that begins a conversation the moment it meets the light, and that conversation becomes a lifetime story when it becomes the center of an engagement ring. This transparent, highly collectible sapphire weighs 4.99 carats, presented in a refined emerald cut shape with dimensions of 8.27 x 7.58 x 8.26 mm, a profile that balances presence with poised elegance. Originating from Ceylon, Sri Lanka, this stone displays a vivid color intensity that shifts from a luminous cornflower blue in fluorescent and daylight to a deep, velvety violet under incandescent light, a natural color change that is among the rarest and most enchanting phenomena in gemology. The gem has been evaluated at eye level as slightly included, which confirms its natural character without compromising the striking clarity and brilliance that make it ideal for daily wear and meaningful ceremony. With an excellent polish and absolutely no enhancement, this sapphire offers uncompromised, natural beauty, a level of authenticity and purity that only a select few gems achieve.

For those who seek an engagement ring that stands apart from every conventional choice, this sapphire is an impeccable option. The emerald cut provides architectural lines and broad facet planes that emphasize the stone’s color change and transparent character, allowing the shifting hues to play across each facet in a sequence of intimate reveals. At 4.99 carats the gem reads as substantial and luxury worthy, while the slightly included clarity lends character and a fingerprint of nature that collectors prize. Sapphires are second only to diamonds in hardness, so a well designed setting will protect this treasure for a lifetime of wear, while honoring the sapphire’s storied symbolism of loyalty, wisdom, and enduring love. Imagine this gem set in a bespoke solitaire that highlights the clean geometry of the emerald cut, or cradled in a halo of small pavé accents to amplify its glow without overshadowing the rare color change. Each view will be a private performance, a shift of mood and depth that mirrors the evolving chapters of a shared life.
