You are trying to do surgery with an ax. Your camera, lighting, and skill is simply not there. Sorry, but that is the simple truth. Not having the money to use a pro photographer does not alter that fact. These photos are going to be representing your product. How willing do you think people are going to be to invest in a product that has a very amateurish, poor quality look to it, which it will doing what you are doing. Shooting outdoors will not help, and will in most cases make things worse. You would have to be under an overcast sky or use a scrim to block out harsh, direct sunlight. But then, proper, diffused lighting is still needed to show the form and texture of your jewelry. I will tell you that even lots of experienced, pro photographers struggle with lighting jewelry and glass. One technique is to not even directly light it at all. Instead, light is directed onto reflectors and light is bounced in a controlled manner back onto the jewelry. Subtractive lighting can be utilized with black panels beside the jewelry to absorb stray light. The jewelry can be placed on glass to get a subtle reflection.
If you are serious about doing this as a business, then you must approach the entire project in a businesslike manner, and that does not mean putting up bad photos of your product. Business is as much an investment as simply making money. Part of your investment is going to be in hiring someone to provide you with proper photographs. If you cannot make that hurdle, then you need to reconsider your business plan.
