Made a common mistake: assuming every stone makes the piece worth more. You probably want a quick answer. Here it is: sometimes yes, often no.

Do diamonds automatically raise the price of a gold piece?
No. A diamond only helps if it has independent value. Small factory-set stones or glued accents rarely add much. Buyers often pay for the gold weight first, then the stone only if it has clear market value.
How do buyers decide if a stone matters?
Buyers look at three things: size, quality, and market demand. Size is carat weight. Quality means cut, clarity, and color, and those are checked by sight or with a loupe (a small magnifier). Demand means whether people want that type of gem now.
What types of stones usually add real money?
Big, clean diamonds and well-known gemstones can add value. Fancy-coloured diamonds, certified diamonds, sapphires, rubies, and emeralds often bring extras. Lab-grown gems usually add less than natural stones, unless the market specifically prefers lab-grown.
What should you check before selling? (quick checklist)
Look for markings or a certificate stored with the piece.
Check if stones are loose or glued; loose stones are worth more.
Note the total carat weight stamped on the item or paperwork.
Inspect for visible chips, repairs, or replaced stones.
Ask if the stone is natural or lab-grown, and if there is a certificate.
Photograph the piece under good light for your records.
How will a pawnshop or buyer test the stone?
They will often do quick checks on the spot. For diamonds, they may use a small probe that senses thermal or electric differences. For coloured stones, they look at colour, surface damage, and heft. If the stone looks promising, they may ask for a certificate or send it for testing. If not, they focus on gold weight.
You meet a seller in person and bring the ring along. The buyer checks the gold stamp and weighs it. Then they tap the stone and look for chips or glue. This short exchange often decides the offer.
Can gemstones lower the offer?
Yes. If the stone is damaged, poor quality, or suspected to be a fake, it can reduce trust. Buyers price in the cost to repair or to remove the stone. If setting removal is hard, that work lowers the cash offer.
Should you remove the stone before selling the gold?
Usually no. Removing a stone without a jeweller risks damage. Buyers factor in removal costs and may still give better total value if the stone stays in place. If you have a strong independent certificate for a valuable stone, show it. If the stone is tiny or glued, removing it rarely improves the offer.
How do certificates and appraisals affect the deal?
A current certificate from a known lab helps. It proves size and quality quickly. An old appraisal, however, may overstate market demand. Buyers prefer up-to-date lab reports for diamonds. For coloured stones, a note from a trusted gemmologist can speed things up.
Negotiation tips when stones are involved
Start with clear photos and any paperwork. Be honest about damage or repairs. Ask how the buyer values the stone versus the metal. If the buyer offers only melt value for the gold, ask whether they can separate stone and metal values. If you want more time, get a second opinion from a jeweller who buys used items.
Bottom line: what to expect
If the stone is small, treated, or low quality, expect little to no extra cash beyond the gold weight. If the stone is large, natural, and has certification, you can expect a meaningful premium. If you need cash fast, selling the whole piece together is usually easier and safer than DIY removal.
If the shop won’t show the scale and test, you don’t have enough information to accept the offer.
Today’s takeaway: If the stone is proven and market-worthy, it adds value; otherwise the gold weight will likely be the main driver of the offer.
