Round shape
A round diamond rewards strong cut quality.
Round brilliants are the easiest shape to benchmark, but the make still matters. Cut grade, table, depth, symmetry, polish, and spread carry the decision.

Short answer
A round diamond rewards strong cut quality.
Round brilliants are the easiest shape to benchmark, but the make still matters. Cut grade, table, depth, symmetry, polish, and spread carry the decision.
Use this rule
Do not judge one C alone. Read the certificate, inspect the actual stone, then decide whether beauty, budget, or resale confidence matters most.
What round diamond searchers need first
Shape changes beauty, risk, spread, and demand. For round diamond, the useful starting point is evidence: the report, the physical stone, the setting or item condition, and the route the owner is considering.
What to check before money changes hands
Check Symmetry, Bow-tie, Spread, Protected points, Colour visibility, and Demand. If one of those is missing, the next step is not negotiation. It is verification.
Where people get caught
Fancy shapes can look larger for the weight, but they need closer inspection than a name or carat figure suggests.
When Prodiam is the right next step
Ask Prodiam to review round diamond make and certificate.

Direct answers
Common questions
Is round diamond enough to value a diamond?
No. It helps frame the question, but value needs the stone, certificate, 4Cs, condition, market demand, and the route being used.
What should I collect before speaking to a buyer?
Collect the grading report, report number, photos, invoice, valuation, estate documents if relevant, and any notes on repairs or resizing.
Should I rely on a quick online estimate?
Use it only as context. Diamonds need inspection and certificate-led benchmarking before a serious value conversation.
