Heavy internal fracturing, clouds, and dark crystal spots visible to the naked eye
Blemishes
Possible surface reaching fractures and slight abrasions on facet edges

Natural; likely extracted from a commercial-grade mine (India or Africa)
Treatment Detection
None apparent; low-grade stones are rarely treated as it is not cost-effective
Estimated Value
$10 - $30 USD per stone (Commercial/Industrial grade)
Certification Estimate
Likely uncertified due to size and low quality; GIA would evaluate as I-range

None; these are decorative accent stones with high depreciation
Similar Diamonds

Setting Suggestions
Currently in a vintage yellow gold prong setting
Care & Maintenance
Gentle ultrasonic cleaning if the stones are not fracture-filled; avoid harsh chemicals
