Due to its orange to red-orange color, topaz generally looks best under incandescent light. In contrast, blue topaz looks best under daylight or fluorescent light. To eliminate any future surprises when buying any gem, it is a good idea to examine it under a variety of light sources.
Due to the shape of the rough elongated prisms, topaz is generally cut as elongated stones, typically emerald cuts, elongated ovals, cushions and pears. To save weight, pears are often cut with overly narrow shoulders. Due to the huge production, blue topaz is cut in virtually any shape and style.
