Key Differences
Dross is typically the by-product of metal refining processes, containing impurities removed from metal ores. Whereas gems are naturally occurring mineral crystals that are cut and polished for use in jewelry due to their aesthetic qualities.
Dross is often considered useless and is discarded, highlighting its low economic value. On the other hand, gems are highly sought after and can command extremely high prices, reflecting their desirability and rarity.
While dross is a result of human industrial activity, particularly in metal production, gems can form through geological processes over millions of years, often deep within the Earth's crust.
In contrast to dross, which is generally regarded as undesirable, gems hold significant cultural and historical importance, symbolizing status, luxury, and beauty in many societies.
The concept of dross metaphorically extends to describe anything deemed superfluous or unworthy, whereas gems are used metaphorically to represent anything of great value or quality.
