来源、4C、证书是否同档Match origin, 4Cs and report
BUYER QUESTION · 预算阶段Budget
同样写着一克拉，钻戒为什么能差几千甚至更多？Why can two one-carat diamond rings differ so much in price?
“一克拉”只说明重量，不说明品质与整件成本。差价通常来自钻石来源、颜色、净度、切工、证书，戒托材质与金重、镶嵌工艺、品牌服务和现货状态。正确比较方式是把同一口径的字段逐项对齐，而不是只看标题里的克拉数。One carat describes weight, not quality or the cost of the finished ring. Price gaps can come from origin, color, clarity, cut, report, setting metal and weight, workmanship, service and stock status. Compare matching fields rather than the carat headline alone.

FAQ
这个问题还常被这样追问Common Follow-Up Questions
便宜很多就一定有问题吗？Does a much lower price always mean a problem?
不能只凭价格判断，但应要求把差异字段完整列出。Not by price alone, but the seller should explain every differing field.
证书一样价格就该一样吗？Should matching reports mean matching prices?
不一定，戒托、工艺、品牌和服务仍会造成差价。No. Setting, workmanship, brand and service can still differ.
