I am new to photo editing and wanted to know the best software that's best for editing jewellery. I am really not sure if Lightroom or Elements would be best and would appreciate anyones expert advise and experience. Maybe there is another software package more suitable, would appreciate anyones help.
That is going to depend on what you mean by edited. Color correction, levels adjustments, contrast, brightness, etc. can be done on any image editing program.
Manipulating the image to make the jewlery look like it is on another person, or another vault. Photoshop or elements would be better.
BTW, just kidding on the vault.
As said above, definitely not Lightroom. You can't make the most of shiney things without selections and layers. As to whether PS or PSE would be better, well the problem with asking that here is you probably won't find anyone who knows anything much about Elements. But if put on the spot, I'd say get a monthly CC subscription. You'll never grow out of it.
