I have been looking for a beautiful pair of diamond earrings. 2ctw. Will be happy to keep it slighly under 2ct to save budget. Can someone please advise whether its better to buy online plus tax and custom or buy in store. I live in Australia and I was offered a beautiful pair at $13500 from Dustin Jewellers and I blew it off. For a similar pair after a year the price is 16500. G SI3.I looked up stones on JA and comes to $16k. With tax it will be around $17-18k.
