We base our prices on the current Rapaport price list as a market reference and on the trading prices recorded on the diamond exchanges. With this sound information, we evaluate your diamonds strictly according to the quality specifications of the well-known 4 Cs.
Upon request, we will provide you with the current price list for your review.

Evaluation criteria
  • Carat weight: the heavier, the more valuable
  • Color intensity: from “faint” to “fancy vivid,” intense colors always achieve the highest prices in an evaluation
  • Color mode/hue: pure hues are the rarest and are evaluated accordingly
  • Clarity: color intensity can compensate very well for minor inclusions
  • Cut: has a decisive influence on brilliance and color perception.
  • Provenance: certifications (GIA, Argyle) or brands such as Graff increase the price.
    In 2025, AI and advanced spectroscopy will also be increasingly used in grading, which will improve certification and transparency and make evaluations even more accurate.
