Materials & Stone Quality

Detail what the piece is made of and translate each material choice into a mark of quality and durability. Work through the metal (type, purity, weight where given), the stones (type, carat, cut, clarity, colour and any grading), and the setting and construction, all sourced from {specifications} and {description}. For each, explain why it matters: how the metal wears and holds a stone, how the stone's characteristics affect brilliance and value, how the setting keeps stones secure over years of wear. Surface certification and hallmarking only where the data documents it, and present it as verifiable assurance. Be precise and avoid vague superlatives; a buyer comparing pieces should understand exactly what they're getting. Never state a grade, purity or certification not present in the product data.
