The group carefully examined the Ruby on the Golden Mask and soon discovered there were indeed some issues.
Most gemstones are considered better the larger and cleaner they are. However, this Ruby was quite large, but not particularly clean, with some inclusions that looked like color paste.
"Is this a fake Pigeon Blood Ruby? Has it been heated or color-enhanced?" Kun Sha asked.
In the past, Ruby could be treated with heat to reduce inclusions, enhancing its color's brilliance.
Such heat-treated Ruby is called "burned" Ruby, whereas non-heat-treated Ruby is termed "non-burned" Ruby.
Burned Ruby is not considered fake but is far less valuable than non-burned Ruby. Unscrupulous merchants sometimes sell burned Ruby as non-burned, which is deceitful.
As for color enhancement, that is true fakery and is extremely unethical.
