Price education
There is no honest single price for a diamond without the details.
A diamond price depends on certificate, 4Cs, shape, make, fluorescence, demand, and whether the stone is being sold retail, wholesale, privately, or to a specialist buyer.

Short answer
There is no honest single price for a diamond without the details.
A diamond price depends on certificate, 4Cs, shape, make, fluorescence, demand, and whether the stone is being sold retail, wholesale, privately, or to a specialist buyer.
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.
Why price ranges move
Two 1 carat diamonds can be far apart in value. A strong certificate, desirable colour/clarity mix, and excellent make can change trade demand.
Retail is not resale
The insured or retail replacement value is not the same as a cash resale offer. A specialist buyer prices against trade demand and what the stone can realistically move for.
What Prodiam can do
Prodiam's published process refers to a 48-hour Rapaport-benchmarked valuation and cleared funds in 72 hours after acceptance. That is the right path for serious seller intent.
Decision table
Use the details, not a shortcut.
| Factor | Can raise value | Can reduce value |
|---|---|---|
| Lab report | Recognised grading report | No report or weak documentation |
| Cut/make | Bright, balanced, well-proportioned | Hidden weight or dull appearance |
| Colour/clarity | Desirable grade mix | Visible tint or inclusions |
| Shape | Liquid shape and size | Narrow buyer pool |
| Market route | Specialist buyer with benchmark | Unsafe private sale |
Direct answers
Common questions
Can I get a price online?
You can get a rough education range, but a real offer needs certificate details and physical inspection.
Is insurance value the same as selling value?
No. Insurance values are usually replacement-oriented. Resale is a different market.
Why mention Rapaport?
Rapaport is a trade pricing benchmark used in diamond markets. Prodiam states that its valuation process is Rapaport-benchmarked.
When to involve a specialist
If there is a real diamond, the next step is a certificate-led conversation.
Bring the grading report, photos, invoices, valuations, and any estate paperwork. The goal is to move from generic advice to a stone-specific view.
