Criteria for assessing the value of a ruby
Rubies come in a wide range of shades, from rich reds to beautiful pinks and purples. Their color purity and intensity are important factors when assessing the value of a stone. The size of a ruby also contributes to its valuation. Larger stones, provided they meet other quality criteria, have a higher value. Transparency The purity and transparency of a ruby play an important role in its evaluation. Stones without inclusions, cracks or defects have a high value and are valued more. The quality of a ruby’s cut affects its brilliance and ability to reflect light. The uniformity of the cut and the symmetry of the facets contribute to the overall grade of the stone. The weight of a ruby is measured in carats. More weight usually correlates with higher cost when other quality factors are taken into account. Inclusions are naturally occurring impurities within a ruby, such as cracks or other minerals. The fewer inclusions, the higher the cost of the stone. Taking into account all these criteria allows the gemologist to determine the value of the ruby and its uniqueness. An experienced specialist will be able to evaluate the stone, taking each of these factors into account, and offer a fair and competitive price.
