The most common gemstone we pay for is diamonds – but we do look for good quality gemstones. It they are of poor quality unfortunately we will not be able to make an offer. We do pay a premium for quality diamonds though. For other gemstones, it is dependent on what it is and again its quality, so we would love to see you in-store or contact us to let us know what you have and we will advise you if it is of any value.
