Why are Topaz and Citrine Gemstones Misidentified?

Answer: Topaz and citrine are definitely not "basically the same." Citrine gemstones, a yellow variety of quartz, are sometimes erroneously identified, even in appraisals, as topaz.

A Little History of Topaz and Citrine Gemstones

Before the 20^th century, all gems in the brown, orange, and yellow color range were called topaz. Modern gemology was only recognized as a science in the 1930s. Now, we recognize topaz and yellow or brown quartz as separate gem species.

Topaz and quartz have different chemical, physical, and optical properties. However, many jewelers have continued to use the old names. Topaz gems occur in red and blue as well as yellow, but the popular association with yellow remains strong.

Topaz and Quartz are Valued Differently

Topazes typically appraise for more than quartz gems of similar appearance. The quartz family of gems is much more common than topaz. So even though they may look alike, the more common quartz varieties are less valuable than topaz.

This might explain why some vendors may refer to yellow or brown quartz as topaz. For example, "smoky topaz" is much more likely to be smoky quartz than actual brown topaz. Citrine gemstones (yellow quartz) are less frequently confused with topaz gemstones, but it does happen.

Appraisers Can Make Mistakes

Some jewelers can perform accurate appraisals. Others cannot. Consumers should realize there are no qualifications or regulations for writing a gemstone appraisal. To protect your investment, contact an independent gemology lab that specializes in identification and appraisal.
