Silk Inclusions
What is Silk?
Silk refers to fine, needle-like rutile inclusions that create a silky sheen within the sapphire. These are one of the most common and desirable inclusions in natural sapphires.
Characteristics:
- Fine, parallel needle-like structures
- Often oriented in multiple directions
- Creates asterism in star sapphires
- Proof of natural origin
- Common in Ceylon sapphires
Value Impact
Impact Level: Low
Silk inclusions typically have minimal impact on value when fine and evenly distributed. In fact, they can increase value in star sapphires by creating the star effect. Heavy silk can reduce transparency and lower value.
Natural vs Synthetic
Silk is a strong indicator of natural origin. Synthetic sapphires rarely contain silk inclusions, making this a key identification feature for natural stones.
Value Impact Guide
Low Impact
Silk, needles, fingerprints, growth lines. These inclusions are common in natural sapphires and have minimal effect on value when small and well-distributed.
Medium Impact
Crystal inclusions, color zoning. These can affect appearance and value depending on size, location, and visibility. May reduce value by 10-30%.
High Impact
Feathers, cavities, large crystals. These significantly affect durability and appearance. Can reduce value by 40-70% or make stone unsuitable for jewelry.
