2.90 Ct. Yellow Rough Sapphire Crystal from Ceylon (Sri Lanka)

This translucent yellow sapphire weighs 2.90 carats and presents in a rough shape with dimensions of 16.31 by 5.67 by 4.02 millimeters. The stone has a rough crystal cut that preserves much of the natural crystalline form while providing defined planes for light interaction. Color is described as medium intensity yellow, offering a clear and approachable hue that remains distinctly sapphire in character without overwhelming saturation. Clarity is graded as very slightly included when evaluated at eye level, indicating minor internal features that do not detract from the stone sightly and that contribute to its natural appearance. The surface receives an excellent polish, which enhances luster and tactile quality while maintaining the integrity of the rough crystal aesthetic. There has been no enhancement performed on this material, and the provenance is Ceylon Sri Lanka, a historic source noted for producing sapphires with refined color and consistent crystalline quality.

Optical behavior for this stone is influenced by both its translucency and the rough crystal cut, which together create a soft, internal glow rather than the sharp scintillation associated with fully faceted gems. The medium color intensity allows light to transmit and scatter across the crystal planes, producing subtle shifts in tone when viewed from different angles. Very slightly included clarity at eye level suggests that inclusions are present but are small and sparse, permitting clear visual appreciation of the color and internal structure without significant obstruction. The excellent polish enhances surface reflection and helps define the interface between the stone and its setting, an important consideration for jewelry that emphasizes both aesthetic presence and wearability. Overall optical qualities support an appearance that is simultaneously natural and refined.

The sapphire’s combination of size, translucency, and durable nature makes it highly versatile for both casual and formal use. With a hardness of nine on the Mohs scale, sapphires are appropriate for everyday jewelry applications, including rings, pendants, and bracelets, while the substantial length of this rough shape lends itself to elongated designs such as bar pendants or bezel set rings with a contemporary profile. For formal settings, the medium yellow tone pairs well with both warm metals like yellow and rose gold and cool metals such as platinum and white gold, permitting designers to emphasize contrast or harmony depending on the composition desired. The stone also offers attractive possibilities when combined with a White Opal, the opal type included in this description, where the opal’s play of light and softer white base can create an elegant counterpoint to the sapphire’s translucent yellow, yielding designs that are refined yet approachable. Whether mounted as a solitary statement piece or integrated into a multi stone arrangement, the sapphire’s understated color and polished finish support both restrained daily wear and elevated evening pieces.

The Natural Sapphire Company offers this untreated Ceylon sapphire with full disclosure of its characteristics and origin, supporting informed design and acquisition decisions. As a natural, non enhanced stone, care recommendations are straightforward, favoring gentle cleaning with warm soapy water and a soft brush to remove surface residues, followed by rinsing and drying with a lint free cloth. Ultrasonic cleaning may be used with caution and only after assessment of any internal features by a qualified jeweler, while steam cleaning and exposure to harsh chemicals should be avoided to preserve the stone and any adjacent materials. The stone’s integrity and polish make it suitable for secure settings that protect the elongated profile while showcasing the crystal form, and its compatibility with a White Opal provides an option for paired designs that balance color, texture, and light. For clients and designers seeking a natural, well proportioned yellow sapphire with clear documentation of weight, dimensions, clarity, cut, polish, enhancement status, and Sri Lankan origin, this gem represents a considered choice from The Natural Sapphire Company.
