Expert Advice
Why Choose Certified Princess Cut Diamonds?
The princess cut is the most popular fancy-shaped diamond in the world — and the second most popular shape overall, behind only the round brilliant. Created in 1980 by Betzalel Ambar and Israel Itzkowitz, this 76-facet square design delivers brilliant-cut sparkle in a bold, geometric silhouette that no other shape can replicate.
Value
Exceptional Value Per Carat
Princess cuts retain up to 80% of the rough diamond during cutting — compared to just 50% for round brilliants. Less waste per carat means a lower cost to you. Combined with slightly lower market demand, princess cut diamonds typically cost 20–40% less than a comparable round, with no sacrifice in sparkle.
Brilliance
76-Facet Brilliant Sparkle
The princess cut's 76 facets are arranged in a distinctive chevron pattern that generates an intense, scintillating light return — rivalling the round brilliant for fire and brightness. Its brilliant-cut geometry means it catches the light from every angle, producing a dynamic and lively play of sparkle.
Presence
Larger Face-Up Appearance
The diagonal measurement of a princess cut is typically 15% greater than the diameter of a round brilliant of the same carat weight. On the finger, this creates the visual impression of a noticeably larger stone — more diamond for your budget.
Versatility
Designed for Every Setting Style
The straight, parallel edges of the princess cut allow stones to sit perfectly flush in channel, invisible and pavé settings — creating seamless lines of sparkle in wedding bands and eternity rings. It looks equally striking in solitaire, halo and three-stone engagement ring settings.
Silhouette
Bold Geometric Precision
The princess cut's perfectly square outline makes a strong, unambiguous geometric statement. Unlike oval or pear shapes, there's no orientation to worry about — the princess sits symmetrically on the finger in any direction, making it one of the most naturally wearable shapes available.
Demand
The World's #1 Fancy Shape
The princess is the most popular fancy-shaped diamond in the world and holds second place overall behind the round brilliant. Its broad appeal across age groups and style preferences ensures sustained demand — supporting long-term confidence in your investment.

Your Guide to Princess Cut Diamonds
Setting recommendations for certified princess cut diamonds
The princess cut's four sharp 90° corners are its only real vulnerability — they can chip if struck at the right angle during everyday wear. For daily ring use, we strongly recommend a 4-prong setting with a prong at each corner: the prongs act as a physical shield without obscuring the stone. V-prong settings offer the most elegant corner protection while keeping the diamond visible. A bezel or semi-bezel setting eliminates corner risk entirely and gives a sleek, modern look — though it covers more of the diamond's girdle.
Avoid open claw settings that leave the corners exposed. Channel settings are an excellent option for multi-stone or band designs. If you're setting a princess as a solitaire, discuss corner protection with your jeweller before committing to a setting style.
What to expect to pay for certified princess cut diamonds
The princess cut is one of the best-value diamond shapes available. Its high rough yield (up to 80%) and slightly lower demand compared to rounds means you typically pay 20–40% less per carat than a comparable round brilliant. As a general guide at G colour and VS2 clarity: approximately €700–€1,100 for a 0.50ct stone, €1,400–€2,400 for a 1.00ct, €2,500–€4,200 for a 1.50ct, and €5,500–€9,000 for a 2.00ct.
At Diamantwerp, our prices are typically 75% below what you would pay at a traditional jeweller for the same certified stone.
Princess Cut Diamonds in Antwerp
Antwerp is the world's diamond capital — over 80% of the world's rough diamonds pass through the city's diamond district each year. Buying certified natural diamonds in Antwerp means purchasing direct from the source, with none of the retail markups added by high-street jewellers or international online platforms.
At Diamantwerp, our office on Pelikaanstraat 62 sits at the heart of the Antwerp diamond district, allowing us to source princess cut diamonds directly from cutters and sight-holders and pass the savings to you.
Princess Cut Diamonds and certification
Unlike round brilliants — which can achieve a Triple Excellent cut grade from GIA — princess cut diamonds receive no standardised GIA cut grade. GIA rates princess cuts on polish and symmetry only, placing greater responsibility on the buyer to evaluate cut quality independently.
When assessing a certified princess cut, review the table and depth percentages on the certificate (ideal table: 65–75%, depth: 68–75%), verify the length-to-width ratio (1.00–1.05 for a square appearance), and inspect the corners for any chips or naturals. Every princess cut diamond at Diamantwerp comes with a verified certificate from GIA, HRD or IGI — and our team walks you through the proportions before you commit.

Whether you are buying a princess cut diamond for an engagement ring, as a gift, or as a long-term investment, purchasing a certified stone from a verified Antwerp dealer is the single most important step you can take to protect both its value and your confidence in the purchase.

Common Questions
Certified Princess Cut Diamonds FAQ
Everything you need to know about buying a princess cut diamond.
Why is the princess cut less expensive than the round brilliant?
Princess cuts retain up to 80% of the rough diamond weight during cutting, compared to around 50% for round brilliants. Less waste means a lower cost per carat. Combined with slightly lower demand, princess cut diamonds typically cost 20–40% less than a comparable round brilliant — making them an exceptional value choice.
Do princess cut diamonds need protective settings?
Yes. The sharp, pointed corners of a princess cut are more vulnerable to chipping than rounded shapes. We recommend settings with V-prongs or bezel corners that protect each corner. Channel settings also offer excellent protection. Your jeweller should always set a princess cut with corner protection in mind. Read our engagement ring guide for more on setting styles.
What length-to-width ratio should I look for?
For a perfectly square appearance, look for a length-to-width ratio between 1.00 and 1.05. Ratios above 1.05 will appear slightly rectangular. Most buyers prefer the square look, but some intentionally choose a slightly rectangular princess for a unique aesthetic. Always check the ratio on the GIA, HRD or IGI certificate.
What colour grade should I choose for a princess cut diamond?
The princess is a brilliant cut, so it handles colour reasonably well — but its square shape and sharp corners concentrate slightly more colour than a round brilliant. For a white, clean-looking stone, G or H is the sweet spot: both face up near-colourless and represent excellent value. D–F is worth the premium if you're pairing with a platinum or white gold solitaire setting. Avoid I–J in a princess — the four pointed corners tend to trap warmth and make faint tints more noticeable than in a round of the same grade. Read our full guide on diamond colour.
How can your prices be so much lower?
We buy directly from cutters and sight-holders in the Antwerp diamond district — cutting out multiple intermediaries. Our low-overhead business model means we pass the savings directly to you. The same certified loose diamonds from Antwerp, at a fraction of the price. Browse diamonds by budget: under €2,000, under €5,000 or under €10,000.
Is a princess cut diamond suitable for an engagement ring?
The princess cut is the second most popular engagement ring shape in the world — combining a clean, modern silhouette with brilliant-cut sparkle at 20–30% less than a comparable round brilliant. The square face-up shape looks striking in solitaire, halo and three-stone settings alike.
The one practical consideration: the four sharp 90° corners can chip if struck at the right angle during everyday wear. A 4-prong setting with prongs at each corner offers the best protection. A bezel setting eliminates the risk entirely but covers more of the stone.
On the finger, a princess sits compact and geometric — it doesn't elongate like an oval or pear, but its bold square shape makes a strong visual statement. We recommend a minimum of 0.50ct so the square outline reads clearly, with 0.70ct or above being the most popular choice for solitaire rings.
