Selling a 1 Carat Diamond: Weight, Reports & Offer Questions
Confirm whether one carat describes a single diamond or the combined diamonds in a piece. Bring the existing report and complete jewelry, then request a purchase offer that identifies exactly what is included.
Confirm what the one-carat description covers
GIA defines one metric carat as 200 milligrams. A one-carat center diamond and jewelry containing several diamonds totaling one carat are different descriptions. Establish which you have before using a price comparison.
GIA’s carat-weight report guide explains the distinction between individual and combined weights. For example, a pair of earrings described as one carat total does not state that each earring contains a one-carat diamond. Read the original wording and ask for clarification where needed.
Bring the full report information
Record the laboratory and report number, stated weight, measurements, shape, color, clarity and any comments. GIA’s sample reports show how fields differ by report service. Match the documentation to the stone being presented rather than relying on a report found with other jewelry.
Two diamonds with the same weight may have different dimensions, appearance and quality descriptions. Use our carat-weight guide to separate measurements from weight. If the stone remains mounted, ask what the evaluator can establish and what must be estimated.
| Bring or record | What it clarifies |
|---|---|
| The complete piece | Whether the setting and additional stones are part of the sale |
| Existing laboratory report | The recorded information for the examined diamond |
| Purchase and repair records | Known descriptions, replacements or alterations |
| Current condition notes | Chips, missing parts or other concerns to examine |
Request an offer for the actual item
Ask the buyer to state what the amount covers. If the offer includes a ring setting, do not add a second metal estimate as though the setting were excluded. If there are accent stones, establish whether they are included too.
A retail listing for another one-carat diamond does not determine the purchase amount for yours. There is no single resale price attached to the weight. Compare firm offers under the same conditions using our diamond resale offer guide.
Clarify missing information before commissioning work
If you have no report, explain what you know about the stone and ask what examination is needed. A new report, repair or removal from a setting may involve time and cost. Discuss the reason for any proposed work and agree on the scope before it begins.
Use the diamond buyer checklist to ask about handling, final amount and payment availability. Keep a written record of the offer so you can consider it without relying on memory.
