Platinum Solitaire Princess Cut — Bold Modern Brilliance
The princess cut is the second most popular diamond shape in the world — and its appeal is unmistakable. With sharp, geometric corners and up to 76 facets, the princess cut delivers exceptional brilliance and fire in a distinctly contemporary silhouette. Four V-prongs protect each corner while keeping the stone elevated for maximum light entry.
The clean lines of the princess cut find their perfect partner in the architectural purity of 950 platinum. The metal's naturally cool-white colour accentuates the diamond's brilliant facets and geometric form. With no need for rhodium replating, platinum maintains its lustre long after gold alternatives would have dulled.
Each princess diamond is independently certified by GIA or IGI, graded D–F in colour and VS1–VS2 in clarity. Free laser engraving up to 30 characters is included, and the ring ships in our signature presentation box — insured, worldwide.
- Up to 76 facets — exceptional brilliance in a bold square form
- D–F colourless, VS1–VS2 clarity lab-grown princess diamond
- 950 platinum — stronger and whiter than any gold alloy
- Official GIA or IGI grading certificate included
- V-prong corners — protection and style combined
- Free engraving up to 30 characters
- 74% less than an equivalent mined diamond ring

"Absolutely beautiful ring. The diamond's corners are perfectly protected by the V-prongs and the stone catches light from every direction. Highly recommend."
◈ Verified Purchase
950 platinum is denser, more durable, and naturally white — it will never require rhodium plating like white gold does. Over time it develops a beautiful patina rather than thinning, making it the superior long-term choice for an engagement ring worn every day.
The princess cut has up to 76 facets optimised for brilliance and fire in a square form. Its sharp corners create a bold, contemporary silhouette that is especially popular with those who want the brilliance of a round diamond but with more geometric, modern character.
The certificate independently verifies your diamond's Cut, Colour, Clarity, and Carat weight. It also confirms the stone is lab-grown. This certificate is your proof of quality and is universally accepted by insurers and jewellers worldwide.
Yes — free engraving of up to 30 characters is included with every ring. You can add your message at checkout. Engraving is laser-etched on the interior of the band and will not affect the structural integrity of the setting.
We offer one complimentary resizing within 12 months of purchase. If you are unsure of your partner's size, we recommend ordering the most common size (EU 52–54) and resizing after the proposal.
