Which trade term refers to a mixture of gem qualities that represents unsorted production from a particular mine?

The term that accurately describes a mixture of gem qualities resulting from unsorted production from a particular mine is "mine run." This terminology is used in the gemstone industry to refer specifically to a collection of gemstones that have been extracted directly from a mine without further sorting or grading. As a result, "mine run" stones may exhibit a wide range of characteristics, including varying colors, clarity, and sizes. This term emphasizes the unprocessed nature of these stones, which can often result in a blend of both high and low-quality gems.

In contrast, other terms like "parcel," "lot," and "batch" typically imply a certain level of sorting or categorization. A "parcel" is often a collection of gems that have been grouped together for sale, possibly based on specific qualities. A "lot" refers to a set of stones that are sold together, which may also have some uniformity in their characteristics. A "batch" usually refers to a grouped quantity of gems or materials that are processed or treated together, indicating a degree of homogeneity. These distinctions are crucial in the gemstone trade, as they affect how gems are marketed and sold.
