Important Lab Disclaimers
​The certificate includes a notable disclaimer at the bottom:
​”Origin & enhancement not checked for the above specimen”
​Origin: This means the lab has not verified where the ruby was mined (e.g., Burma, Mozambique, etc.).
​Enhancement: This is a critical detail for rubies. Most rubies on the market undergo heat treatment or lead-glass filling to improve clarity and color. Since this was not checked, the stone’s value could vary significantly depending on whether it is “unheated” or has undergone “significant treatment.”

Note: If you are considering purchasing this stone, it is often recommended to get a secondary opinion from a globally recognized lab (like GIA or IGI) if you need to confirm whether the stone has been treated, as this heavily impacts its market value.
