What to know about gemstone appraisal in Paris
The appraisal of a gemstone aims to determine the value of the stone. To do this, you need a gemologist, a jeweler, or a goldsmith, who must be experienced in this field and possess the necessary equipment.
The thoroughness of the appraisal depends on the information you need.But with a gemologist, you get all the elements needed to determine the price of a gemstone:
- the nature of the stone, for example a diamond,
- its color (hue, tone, and saturation),
- its cut or shape (round, oval…) and the quality of the cut, depending on proportions and symmetry,
- its origin,
- its clarity (according to inclusions)
- any treatments applied: traditional heating does not or only slightly affects the value of a stone, as with heated sapphire, but other treatments significantly lower its price;
- the carats.
A gemologist can provide you with a laboratory certificate, to make this expertise official and certify the value.As the gemstone appraisal in Paris varies depending on the professional's services and the testing equipment available, it is sometimes possible to have only a stone identified. This is what some people are looking for. For example, to identify a sapphire or am I in possession of a genuine ruby?
