Topaz gemstones showcase vibrant colors and unique cuts.
Color is one of the most important factors in determining the quality of topaz. The intensity, saturation, and hue of the color play a significant role. For example, in blue topaz, a vibrant and saturated blue color is highly desirable. In pink topaz, a pure and intense pink color is sought after. The color should be attractive, even, and without any noticeable zoning or discoloration. Clarity refers to the presence of internal flaws, known as inclusions, and external blemishes in the gemstone. Topaz with high clarity and minimal inclusions is considered more valuable. Inclusions can affect the gemstone's transparency and overall appearance. However, it's worth noting that certain topaz varieties, such as the highly prized imperial topaz, can sometimes have "silk" inclusions that create a desirable effect known as "cat's eye" or "star" in the gemstone.
The treatment of topaz can affect its quality and value. Natural, untreated topaz is generally more valuable than treated topaz. Common treatments include irradiation to enhance color, heat treatment to remove color zones or improve clarity, and coating to create certain effects. Treated topaz should always be disclosed and clearly identified when sold. Topaz Selection of cut and cutoff grade

Larger topaz gemstones are generally rarer and more valuable, especially if they possess excellent color, clarity, and cut.
