A good appraisal takes time, expertise and a lot of experience especially with alexandrite. Jewelry stores who offer some sort of verbal appraisal aren´t doing their job properly and when appraiser´s first claim is that "you paid to much for that gemstone", then you are not getting an appraisal, but you are a victim of a practice known as low-balling. Your best choice is a professional appraiser from a major appraisal organizations, with standards of education and codes of ethics. To protect the client they use methodologies that provide some assurance of accuracy.
