A guide for this piece: about $18,567, 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.

A blue oval and a clear faceted stone face one another across the broad, diamond-set shoulders of this Cartier Toi et Moi ring.
The Piece
Rear views show separate open-backed settings, while additional original photographs show the accompanying repair and gem papers. The historical sapphire figure is 3.67 ct, with Sri Lankan origin and no-heat claims that still require matching to the actual report and stone. The diamond record gives 2.05 ct and the shorthand E/VVS1/VG. Those are historical documented claims, not newly issued grades. The visible paired-stone design does not independently establish a production date or a previous owner.

Condition
Historical A+ follows maker maintenance, with a repair statement included in the accessory record. That does not establish unused condition, currently secure stones or a continuing service warranty. Maker size 52 and the historical Japanese 12 notation are retained as recorded sizing conventions, not a guaranteed present fit. GIA, identification and repair papers must be checked for correspondence before relying on their claims. See every photograph before deciding; they are part of the description. See Japanese condition ranks.
Authenticity & Care
Protect the large stones and raised shoulders from impacts, and keep the ring separately in a soft-lined compartment. Do not rely on a historical unheated claim when choosing a cleaning method: a gem specialist must assess the actual sapphire and existing settings first. Avoid ultrasonic, steam and harsh chemical cleaning until that review. Have a qualified jeweller inspect claws, shank and stone edges before wear or resizing. Historical papers do not establish legal title, current gem condition or an independently verified manufacture date.
Delivery from Japan
Ask about protective packing, availability and destination requirements before dispatch; no unverified transport or maker-service promise is made.
