Diamonds may be forever, but their market prices certainly aren’t. Cut fashions evolve, labgrown stones compete for wallet share, and macroeconomics tug wholesale rates up and down. That’s why any responsible seller starts with an independent appraisal that distinguishes retail fantasy from gemlab reality. In Berlin, one of the most respected venues for such evaluations is the multilingual desk at diamond appraisal Berlin.
Here, gemmologists certified by both the German Gemmological Association (DGemG) and the Gemological Institute of America (GIA) assess the famed “Four Cs”—cut, colour, clarity, carat—under stonespecific lighting and with calibrated microscopes. They also examine fluorescence, symmetry, and any laser inscriptions that anchor a stone to an existing certificate. If you lack paperwork, the lab issues a new grading report accepted by insurance companies and international auction houses alike.
Understanding a report’s jargon is crucial. A flawless Dcolour round may fetch a blockbuster price, yet a Jcolour VS2 princess cut of identical weight could be worth 60 % less. Appraisers translate these nuances into euro figures pegged to Rapaport lists and German wholesale demand. They also explain liquidity: large stones above three carats can take weeks to match with buyers, whereas subonecarat stones trade daily.
Security matters, too. The Berlin lab maintains onsite CCTV, dualsafe storage, and chainofcustody paperwork, so you never fear “stone swapping.” Should you choose to sell, the inhouse buying division presents an offer on the spot, often within 5 % of Rapaport minus standard dealer margins. Prefer an international auction? Staff can consign your stone to Geneva or Hong Kong sales, advising reserve prices and logistics.
Tax is often overlooked. In Germany, private individuals selling personal assets enjoy a oneyear speculation window; profits on stones held longer than 12 months are taxfree. Appraisers can provide documentation proving your holding period—indispensable evidence if Finanzamt questions arise. Combine that with transparent grading and you’re ready to navigate Berlin’s diamond marketplace with professional confidence rather than mere hope.
