I've been checking out this website,
ItsHot
They don't have weight listed for all the pieces, but the listings that do have info, some are as low as 90% over current gold spot/scrap (~$1100 troy ounce atm, but finance gurus speculate this may drop 20% in the near future), nothing over 120% that I've looked at yet. They have a rewards/point system and they send out coupons, both of these can be combined. No tax, except orders in NY, and free ground shipping for orders over $150.
That's not a bad jewelry premium!
They do have some super bling pieces, but I didn't check those out, I'm a fan of plain and casual sold gold and .925 jewelry, stuff like Blue Nile's non-stone stuff.
Here's a coupon code they sent me for signing up, 37DC7E, 5% for the next 30 days. However, I just placed an order (14k rose gold bracelet) and I don't know if it is one time use or what. I hope they send out bigger coupons in the future!!
And if anyone knows of sites like this, that carry at least a few modest pieces, please link them. I don't like all that fancy designer stuff, well except T&Co - I like their simple pieces.
