Hey, I've always send my jewelry with full insurance and transporter like fedex or EMS, cost more but never had issues with them.
This ring has been sent to Australia trough EMS Canada on friday and just arrive today (and the bride like it a lot
).
You can ask for sure, I sell it 2200 AUD (around 1600 usd), 18 karat white gold with 0.12 ct of diamonds and an Akoya perle (a sea pearl from japan).
