First class rates are currently shipping at $3.00 for all jewelry.
International shipping ranges somewhat between the listing from $8.60 to $13.00 depending on the country. Shipping internationally for items over $45.00 must be by priority paid by the buyer to assure it arrives. If you are over-charged on shipping, I do refund the difference automatically after printing the shipping label.
The reason for the somewhat not quite flowing shipping is as a Shopify customer - you need to pay for certain features and it would more than double the subscription per month to add that feature while the shop is still growing. This will be changed at some point when we have supporting sales to warrant the increase in the overhead. Thank you for enduring this with us.
