How to price goods for wholesale and retail.
Look what others charge.
Often products sell at price points.
Computers are an obvious example. In the UK you get the 1000, 1500 pound
points. Fast food is another. In fast food restaurants you get the individual dishes and meals at clustering at certain amounts.
Check the market and copy it!.
If you are selling to retailers, they expect to mark up. I would reckon in
jewelry they would double their buying price.
So your price - direct to public = market price point
- to retailer = half market price point
