EXCEPTIONAL YELLOW INTENSE SAPPHIRE - GEM QUALITY SRI LANKA (CEYLAN) - Height: 5 mm - Width: 3.5 mm- 0.12 g - (1)

Exceptional natural Sri Lankan sapphire in a particularly vivid yellow, remarkable for its transparency, brightness and raw crystal architecture.

Stunning rough natural sapphire from Sri Lanka (Ceylon), showing a spectacular lemon-yellow to golden-yellow color, weighing 0.62 carats with approximate dimensions of 5 × 3.5 × 3.2 mm.
This stone immediately draws the eye with the intensity of its color. Its extremely bright yellow seems almost to emit its own light when the crystal is properly illuminated. Its beautiful transparency allows light to penetrate deeply into the material, revealing a fascinating network of reliefs, internal structures and natural surfaces.
This is a particularly aesthetic specimen for collectors seeking natural Ceylon corundums in unusual colors, kept in their rough form.

An exceptionally bright yellow color

The dominant feature of this stone is undeniably its color.
The crystal displays a vivid, saturated lemon yellow, evolving toward yellow-gold and slightly greenish-yellow tones depending on its orientation and lighting. This variation gives the stone a great deal of dynamism. The most transparent parts become almost solar yellow when traversed by light, while thicker areas develop deeper, golden tones.
The contrast with a black background further enhances this remarkable brightness.

A very beautiful natural transparency

Despite being in a completely rough state, the crystal has large zones with excellent light transmission.
This transparency allows a deep view into the gem’s interior. Light passes through certain parts almost directly before being reflected by the various internal surfaces.
The result is particularly spectacular under point lighting: the stone takes on an almost incandescent appearance, with flashes ranging from pale yellow to extremely intense golden yellow.
The internal structures and natural inclusions visible inside the crystal fully contribute to its aesthetics and testify to its raw mineral character.

A fascinating internal architecture

Viewed in macrophography, this tiny crystal of only a few millimeters reveals a true miniature crystal landscape.
Rough surfaces, natural fractures and internal reliefs multiply reflection effects. Some areas are perfectly vitreous and bright while others display much more complex textures.
There are also some darker, more contrasted zones within the crystal. They add depth to the whole and stand out strongly against the pale yellow transparent matter.
Each change of orientation thus reveals a new configuration of reflections.

Remarkable glassy luster

Corundum naturally develops a powerful vitreous luster, particularly spectacular when the material has good transparency.
This stone is an excellent example of that.
Its different surfaces reflect light at very varied angles, creating a multitude of small white, silver and golden flashes.
Some relatively smooth faces produce frank reflections, while naturally rugged surfaces diffuse light and give the crystal a scintillating appearance.
This combination of transparency, chromatic saturation and luster is one of the specimen’s main aesthetic attractions.

A true rough Ceylon gemstone

The stone has retained an entirely natural morphology.
It is neither faceted nor transformed: its irregular silhouette allows direct appreciation of the material’s gem-like appearance before any lapidary intervention.
Its relatively large volume for its dimensions, notably with an thickness of about 3.2 mm, also contributes to the depth of its color.
This rough preservation makes it both a natural gem and a small mineral specimen.

Sri Lanka, historic land of sapphires

Sri Lanka, formerly Ceylon, has a gemological history globally renowned.
While blue sapphires are its most iconic stones, Sri Lankan deposits are also known for producing corundums displaying a remarkable color diversity: yellow, orange, pink, violet as well as various intermediate tones.
Yellow sapphires thus represent a particularly interesting facet of this chromatic diversity.
This specimen magnificently illustrates this richness with a particularly bright yellow color and a very different appearance from the traditional blue sapphire.

A piece for the collector

This crystal combines several particularly interesting qualities in one stone: prestigious origin, extremely vivid color, good transparency, a weight of 0.62 carat, and an aesthetically striking rough morphology.
It will naturally find its place in a collection devoted to colored sapphires, natural corundums, Ceylon gemstones, rough stones or gem-quality minerals.

Macrophotography allows us to appreciate the finest details, but this stone should also be observed from different orientations and under different lights: its appearance changes considerably depending on how light traverses the crystal.

A remarkable 0.62-carat natural Ceylon sapphire, with a dazzling lemon-yellow color, whose transparency and brightness reveal all the beauty of natural corundum in its rough state.
