"Verbal Appraisal Service" refers to a service that provides a verbal assesment and expected sale value for an opal without including certification or a photograph. This service may be used for assessing the quality, authenticity, or value of opal gemstones. A verbal valuation can be booked in-store or using zoom, messenger or skype. Once you have purchased your "verbal" we will book a time to view your opals. A verbal appraisal usually lasts 15 minutes and can cover whatever Opal is presented at the meeting.
