Frequently asked questions
Can I buy gemstones as an investment?
Yes. Certified gemstones are increasingly seen as alternative assets with attractive long-term returns. Unlike traditional investments such as stocks or bonds, high-quality gemstones are tangible, scarce, and historically preserve value even in times of economic uncertainty. With rarity, certification, and global demand, they can offer stable appreciation alongside your jewelry or investment portfolio.
Is payment through escrow possible and safe?
Yes. At Douma Gems your purchase is fully protected. We offer a money back guarantee on all orders. For amounts from two thousand euro we can use escrow on request. Our trusted escrow partner holds the funds until you receive and approve your gemstone. This gives safety and transparency in every transaction.
How long does delivery take?
We ship insured and with tracking. Most orders arrive within one week, depending on your location.
Can I return a gemstone?
Yes, you may return within 30 days if the gemstone is unused, in original condition, and with the certificate included.
Are all gemstones certified?
Almost every gemstone comes with an internationally recognized certificate (e.g. GIA, IGI, HRD, or NEL) guaranteeing authenticity and quality.
Do you ship internationally?
Yes, we deliver worldwide. All shipments are fully insured to ensure safe arrival.
Can I use your gemstones for custom jewelry?
Absolutely. Our gemstones are selected for both investment purposes and for creating exclusive, timeless jewelry.
