Personal Note From Natural Gems Belgium:

• cut grade : good
• color : activation of play of color needs direct sunlight or flashlight
• symmetry : fair
• polish : good
• carat weight : fair

Natural Gems Belgium reduced the normal price with 50 procent due to the smoking procedure to enhance colors, and play of color. The play of color is fair, but with additional light or in direct sunlight good.
