Which Diamond Cut Holds Value?

November 14, 2025

If you’ve ever wondered “which diamond cut holds value?”, you’re asking one of the smartest questions a buyer can ask. Value isn’t driven by cut alone; it’s a mix of popularity, cut quality, certification, rarity, and market demand. This guide walks you through the cuts that traditionally retain value best and the practical steps you can take to protect the worth of your purchase.

The Answer: Round Brilliant Leads the Pack

Historically, the round brilliant cut tends to hold value best. Why? It’s the most popular cut worldwide, has highly standardised grading (cut grades from top labs are well established), and buyers consistently favour its maximum brilliance. That steady demand helps rounds maintain stronger resale recognition and broader buyer interest.

How Other Cuts Compare

Cut	Typical value retention	Why (practical reasons)
Round Brilliant	High	Universal demand, consistent cutting standards, strong secondary market
Princess	Good	Popular, brilliant-cut square that appeals to many buyers
Cushion	Moderate-Good	Vintage appeal; demand varies with fashion cycles
Oval / Marquise / Pear	Moderate	Can appear larger per carat; demand more taste-driven
Emerald / Asscher (step cuts)	Variable	Valued for elegance and clarity, but resale depends on clarity and buyer preference
Radiant / Trilliant	Moderate	Brilliant-style flash; less standardisation affects resale predictability

Why Does Cut Quality Matter More than Shape

Cut quality (how well a diamond’s facets are proportioned and finished) often matters more to perceived value than the shape name alone. A well-cut princess or oval can look far more brilliant and therefore more desirable than a poorly cut round. When thinking about long-term value, prioritise excellent/very good cut quality and ask to see performance photos or light-return reports where available.

Other Major Factors that Affect Resale Value

Certification:
Stones graded by reputable labs (GIA, AGS) sell more easily. Keep the report and laser inscription if present.
Carat and clarity:
Larger, eye-clean stones and top color grades are easier to resell. Step cuts demand higher clarity to look their best.
Market trends & provenance:
Fashion shifts and origin (lab-grown vs mined) affect demand; lab-grown diamonds currently tend to have lower resale values.
Condition & paperwork:
Original receipts, appraisals, and a well-maintained setting boost buyer confidence.

Practical Tips to Protect Value

Choose classic shapes if resale predictability is a priority.
Prioritise an excellent cut and a reputable certificate. That combination sells best.
Keep documentation in a safe place.
Consider lab-grown trade-offs great for budget and size, but treat resale expectations differently.
Work with trusted jewellers and get a written appraisal for insurance and resale clarity.

Final Thoughts

So, which diamond cut holds value? Round brilliants generally lead because of sustained demand and standardised cutting; princess and other popular brilliant cuts follow closely. But the clearest single rule is this: a high-quality cut plus strong certification and documentation will protect value far more reliably than shape alone!
