3.33ct Topaz, Guerrero, Mexico
Custom design and cut by Daniel O’Neil
Treatment: Possible Radiation
12.14 x 6.63 x 4.62 mm
A classic, intensely dichroic Guerrero topaz from Mexico with a brilliant polish. Topaz in darker colors is becoming extremely rare, and the mine that produced this material has been closed/flooded for many years. Few gem materials exhibit such pronounced dichroism, and this one has been cut to maximize the effect, showing light brownish-orange and burgundy on face-up but burnt orange when viewed from the side. A few very small inclusions, eye clean. We do suspect this piece may have been irradiated, but the treatment is undetectable and stable. Extensively UV tested.
