Blue Nile is GST registered in Australia and therefore their prices include GST on their site for viewers in Australia. I have multiplied the other vendors’ prices by 1.1 to show the price including GST, though the GST component will not be due until the item is received by you.
**The Art of Jewels has a $US50 fee for shipping to Australia which I have not included in the price. However they do currently have Valentine’s Day coupon codes which will offset the price by a lot more than $50.
Prices may vary if exchange rates move.
