Lab-Grown Princess Cut Diamonds: The Complete Guide
A Princess cut lab-grown diamond is a square brilliant-cut stone known for sharp, contemporary lines and lively brilliance. Its faceting delivers crisp scintillation within a clean geometric outline, with an ideal length-to-width ratio of 1.00 to 1.05. It suits anyone wanting a modern square look with sparkle close to a round, often at better value.
Overview
The Princess diamond is a modern, square or rectangular cut that has rapidly become a favourite for its combination of brilliant sparkle and contemporary design. It is known for its sharp, defined corners and sophisticated faceting, which work together to produce a vibrant display of light. The princess cut is celebrated for its balance of modern aesthetics with the classic appeal of a symmetrical, well-proportioned stone. Its clean, angular lines make it particularly popular in engagement rings and fashion-forward jewellery.
Origin and development
Introduced in the 1960s, the princess cut was developed as a fresh, modern alternative to the traditional round brilliant. Its creation was driven by the desire to offer a diamond that combined contemporary design with exceptional light performance. Over the decades, it has grown in popularity due to its versatility and ability to convey both modernity and classic elegance. Today, the princess cut remains a symbol of innovation and style, appealing to those who appreciate cutting-edge design combined with timeless beauty.
How the princess cut is shaped
The princess cut is characterised by its square or slightly rectangular form with pointed corners and a brilliant faceting pattern reminiscent of the round cut. The design focuses on achieving optimal light return through precision alignment of facets, creating an intense, lively sparkle. The geometric, angular shape gives it a modern, edgy appeal that is both stylish and versatile. Its structure is both contemporary and timeless, fitting seamlessly into various jewellery settings, from solitaire rings to intricate multi-stone designs.
Why choose a princess cut
Princess-cut diamonds are renowned for their exceptional brilliance and fire. The cut’s numerous facets are meticulously arranged to reflect and refract light, resulting in a dazzling display of sparkle. Its modern shape and clean lines provide a bold, sophisticated look that appeals to those seeking a contemporary alternative to the traditional round diamond. This cut maximises both beauty and value, offering high-impact visual performance and versatility in various jewellery designs.
What to look for when buying
Prioritise cut quality first: it drives the light return that makes the stone come alive. We screen proportions, polish and symmetry before a stone is ever shortlisted. Every CRTD stone is independently certified by IGI or GIA at a VS1 minimum clarity.
Price
Lab-grown princess cut diamonds at CRTD start at $990 AUD for a one carat stone, with AU-inclusive pricing, the number you see is the number you pay. Larger carats and higher clarity grades are priced transparently across the range.
Choosing well
The Princess cut's pointed corners are its most vulnerable feature, so it is best set in a protective V-prong setting that shields each tip from knocks and chipping. When comparing stones, inspect the corners closely for chips and check that colour reads evenly across the square face, since the cut can concentrate tint toward the edges. Both are straightforward to assess on a certified stone with clear imaging.

Common questions
What is the ideal length-to-width ratio for a Princess cut diamond?
For a true square outline, look for a length-to-width ratio between 1.00 and 1.05. At 1.00 the stone reads as a precise square; toward 1.05 it takes on a subtle rectangular character that some prefer. Both sit within the ideal range, so choose by the look you want rather than treating one as superior.
Are Princess cut diamonds durable enough for everyday wear?
Yes, with the right setting. The Princess cut is a brilliant cut with sharp pointed corners, which are the part most prone to chipping. A protective V-prong setting cradles each corner and shields it from knocks, making the stone well suited to daily wear in rings while keeping its crisp square silhouette intact.
How do I check a Princess cut for inclusions and colour?
Screen for two things: corner chips and even colour. Inspect each pointed corner for nicks or fractures, since these tips are the most fragile. Then check that colour reads consistently across the square face rather than pooling at the edges. Every CRTD Princess cut is independently certified by IGI or GIA at a VS1 minimum clarity to support this.
