Provide buyers with as much information as possible. 

While appraisals are useful, official diamond grading reports from independent sources such as the GIA, AGS, IGI or EGL USA are more valuable to potential buyers.  In the case of larger diamonds, the center stone detail is the most important. Information regarding carat weight, color, clarity and cut will help potential buyers compare apples with apples. Official diamond grading reports from the GIA are incredibly detailed and accurate. People trust these reports and will be willing to pay more as a result.

Provide good quality high resolution images.

While everyone is not a photographer, the following tips might help you take better pictures. Use the macro feature of your camera; do not use the zoom option. Use a background that contains plenty of natural light, you should try taking photos near a window. Your camera or smart phone will need to be brought close to the jewelry to get the best picture. Amazon now sell inexpensive attachments for smart phones that will help you magnify the diamond without detracting from the quality of the photo.

Be responsive to interested buyers. 

Often people are under a time crunch to make the big purchase. If you are slow to respond to interest then the opportunity may be lost. Often you will find that a buyer will pay a premium if they need it quickly. Why shouldn’t you benefit!
