A guide for this piece: about $828, based on the 10% US charge on the declared value of goods made in Japan.
The final figure is set by US Customs and depends on where the piece was made and the kind of object it is. Many antiques over a century old carry no ordinary duty; most jewellery and leather goods add a single-digit rate.
With EMS, any charge is collected by your postal service on delivery. For pieces of significant value we can often arrange duties prepaid before dispatch.

Authenticity & Care
Have the stone settings and fit checked before regular wear. Diamond hardness does not prevent impact damage or loose settings. Avoid home steam or ultrasonic cleaning, which can loosen stones; use gentle handling and seek a specialist assessment of the polished surface.
