Discover the True Worth of Your Diamonds
Many jewellers and buyers undervalue diamonds by overlooking cut, colour, clarity and carat. At Gold Corp, every stone is assessed with precision and compared to live market demand, ensuring you receive a competitive offer that reflects its real value. Whether loose or mounted, your diamonds are worth more with us.
Expert Diamond Appraisals You Can Trust
Our specialists carefully evaluate every diamond using the four Cs — cut, colour, clarity and carat — alongside certification and market demand. Whether it is a loose stone or part of a jewellery piece, you will receive a free, transparent appraisal that gives you complete confidence in the value of your diamonds.
Clarity at Every Step
Certification helps but is not required. Our experts grade every diamond in-house using industry standards, so uncertified stones still receive accurate valuations.
Only if needed and only with your approval. We can often value mounted stones without removing them.
We use the four Cs, compare with live international markets, and explain our process clearly so you see exactly how your offer is calculated.
Many jewellers undervalue diamonds to maximise their margins. At Gold Corp, our business is built on fair, competitive payouts that reflect true market value.
Yes. Once you accept our offer, you receive immediate cash in person or a same-day EFT through our insured courier service.
