This piece of jewelry comprises a band crafted from a gold alloy, specifically one that is 14 parts gold and 10 parts other metals. It is set with a precious gemstone from the corundum family, characterized by its blue hue (though other colors are possible). The combination represents a synthesis of valuable materials, offering a visually appealing and potentially durable ornament.
The inherent value stems from the gold content, a historically recognized and globally traded commodity, and the perceived rarity and beauty of the gemstone. This combination has historically been associated with status, sentiment, and enduring elegance. The choice of materials contributes to both the aesthetic appeal and potential longevity of the item, making it a popular option for commemorating significant events or expressing personal style.
