Whether a loose diamond, an engagement ring, or a family heirloom set with a colored gemstone: at Juwelier Kronenfels in Düsseldorf you receive a gemologically sound appraisal of your diamonds and gemstones. We examine every stone individually, explain our valuation criteria clearly, and then present you with a fair purchase offer.
A certificate from a recognized institute such as GIA or IGI speeds up the valuation, though it is not strictly required, as we have the necessary gemological equipment ourselves.
We buy both loose diamonds and stones set in rings, necklaces or earrings. We also appraise colored gemstones such as sapphire, ruby and emerald. For set stones, we assess both the precious metal of the setting and the stone or stones, so you receive one overall offer for the complete piece.
The value of a diamond can hardly be estimated reliably with the naked eye. Our gemological examination with loupe, microscope and refractometer ensures that you neither sell below nor above value, explained transparently and clearly.
