2.03 Ct. Bi Color / Parti Sapphire from Ceylon (Sri Lanka)

One transparent 2.03 carat round bi color parti sapphire is presented, with dimensions 7.23 x 7.23 x 5.08 mm. The gem is faceted and finished in a mixed brilliant cut, delivering controlled light return and balanced scintillation. The clarity grade is very slightly included, evaluated at eye level, indicating minimal internal characteristics that do not significantly diminish visual performance under casual inspection. The color shows distinct bicoloration within a single stone, with medium color intensity that yields subtle contrast between the zones, and the polish has been graded excellent, producing clean facet junctions and crisp reflections. No enhancement has been applied to this material, and the origin is Ceylon Sri Lanka, a provenance noted for producing a wide range of sapphire colors. The Natural Sapphire Company provides this description based on gemological assessment, and photographic images accompany the report to illustrate the facet pattern and color distribution.

On the Mohs scale of hardness, sapphire is a nine, which places it directly below diamond at ten and above commonly used gem materials such as topaz at eight and quartz at seven. This ranking indicates excellent resistance to scratching in normal wear situations, and it supports use in rings and other frequently worn jewelry where surface durability is a priority. While hardness is a key factor for scratch resistance, it is not the only measure of durability. Corundum exhibits good toughness and lacks perfect cleavage, which reduces the tendency to split along defined planes, however sharp impacts or blows to facet edges or girdle areas can still produce chips or fractures. The absence of enhancements on this stone preserves its natural structural characteristics, and the very slightly included clarity means the stone will perform well in most wear scenarios while still requiring sensible handling. Routine care with a soft brush, mild detergent and warm water is appropriate, and professional inspection is recommended if the stone is to be set into a design that will experience significant mechanical stress.
