Diamond Color Treatment and Its Identification | GIA Knowledge Sessions Webinar Series

GIA Knowledge Sessions Webinar - recorded live on June 25, 2020.
Natural fancy color diamonds acquire their color in a variety of ways, such as through trace elements, radiation and crystal lattice distortion. What about laboratory-grown fancy color diamonds? Or natural diamonds that have undergone treatment to change or improve their color? How are they created or treated and how do GIA scientists detect them? Tune in as Dr. Wuyi Wang, vice president of research and development, offers insight into diamond coloration, treatment techniques and the identification challenges facing gemologists today.

En México existen bastantes diamante de color fancys.. Colecciono y los compro a precios muy bajos...

[@sergpie]

Será que tales colores habrán sido logrados por la implementación de algún tratamiento químico, térmico y/o radiológico? Además, tendrás algún certificado por los mismos que elucidaría la autenticidad y el origen de sus colores? Viajo a Mexico por negocio, y afuera de ciertas especies minerales autóctonas (Titanita, amatista, boleita, danburita etc.) el mercado de gemas finas en Mexico se me hizo bastantemente escaso; afuera de grandes casas joyeras nacionales y internacionales en DF, GDL, MTY, uno verdaderamente batalla en conseguir piedras sueltas. Sin embargo, suerte en su búsqueda y en el nutrir de su pasión.

I’m taking that the id100 can distinguish between irradiated blue diamond vs all natural blue?

I have question about the diamond lab ?. Did they make from another synthetic diamond raw material or not ?? Or maybe they process before from genuine, natural diamond ?? Its look Like from natural diamond they make treatment procces to change their colours, because I really dunno and dont understand! Actualy Gia , should be give knowledge to people , willl be good like short film with animation circle process then easy for people buyer to understood, because so many people dont understand , that will help many peoples decided to buy or not buy , visual circle process can make good answer and give knowledge to market , Thanks
