What type of gemstones are typically found in the commercial market?

The focus on average-quality gemstones in mass-market jewelry reflects the reality of the commercial market, where accessibility and affordability are key. Mass-market jewelry is designed to appeal to a broad audience, and therefore, it often utilizes stones that are more abundant and less expensive. This allows for a larger volume of sales at a lower price point, making it appealing to everyday consumers.

High-quality gemstones, while valuable, are often reserved for investment purposes or high-end pieces due to their higher cost and limited availability. Rare gemstones are typically sought after by collectors and are not as prevalent in everyday commercial offerings. Likewise, luxury gemstones, while important in the luxury market, cater to a niche audience that seeks exclusivity and is willing to pay a premium, which contrasts with the mass-market focus on affordability and availability. Thus, average-quality gemstones serve the needs of the majority, making them the predominant type in the commercial market.
