款式与颜色选择更灵活，需看具体结构Flexible design and color options; inspect structure
BUYER QUESTION · 选款阶段Selection
钻戒选18K还是PT950？日常戴哪个更合适？Should I choose 18K or PT950 for a diamond ring worn every day?
18K与PT950没有绝对优劣。复杂镶嵌、颜色选择和结构强度常让18K更灵活；偏好铂金天然白色、较高纯度和重量感的人会考虑PT950。真正要看的是款式结构、金重、佩戴习惯、是否容易改圈及售后，而不是只看材质名称。Neither 18K nor PT950 is universally better. 18K often offers flexibility for complex settings, color and structure; PT950 appeals to buyers who prefer platinum's natural white color, higher purity and weight. Consider design structure, metal weight, wearing habits, resizing and service rather than the label alone.

EVIDENCE BOUNDARY
本页证据说明Evidence Boundary
下方分别展示 18K 与铂金戒指的公开记录，但并非同款同参数对照；价格差异不能直接归因于戒托材质，耐用和改圈范围也需按具体结构核对。The public listings show 18K and platinum rings, but they are not matched designs with identical specifications. Their price gap cannot be attributed to metal alone; durability and resizing depend on each setting.
商品卡展示公开快照字段，不等于独立实物、单颗主钻、证书或交付核验。Product cards show public snapshot fields, not independent verification of the physical item, a single center stone, a report or delivery.
本页只使用匿名公开商品快照，不展示内部源头价、客户数据或私有库存字段。This page uses only the anonymous public catalog snapshot and never exposes internal source prices, customer data or private inventory fields.

FAQ
这个问题还常被这样追问Common Follow-Up Questions
18K白金等于铂金吗？Is 18K white gold the same as platinum?
不等于。18K白色金合金与PT950铂金是不同材质。No. 18K white gold alloy and PT950 platinum are different materials.
PT950一定不会变形吗？Can PT950 never deform?
任何戒指都受结构、厚度和使用方式影响，不能只凭材质保证。Any ring depends on structure, thickness and use; the metal label alone is not a guarantee.
