Next to the buy now option it says it starts at 2000+ and the shortest time was 3 days which is what I chose when I listed the necklace. It has a day left so just keep watching and bid what you have. There aren't any bids so you never know you might win it!
I have never gotten over 2000 for any item of jewelery I have posted which is why I am not willing to use the buy now option. Just keep watching if your interested in the necklace or bid if you want!
