Import Tips
• Obtain GIA or equivalent gemological certification verifying natural origin and sapphire identity to avoid misclassification as synthetic
• Declare exact weight in carats and provide invoices detailing cut type (e.g
• faceted) as 'otherwise worked' excludes unworked stones
• Beware of common pitfalls like under-declaring carat weight, which can trigger audits; use calibrated scales for accuracy
