Product Details

Design Intent

This design is built for presence. A round diamond illusion setting and reverse halo work together to enhance the visual size and brilliance of the centre stone, while a full eternity shank delivers uninterrupted sparkle around the finger. The result is a ring that feels bold, luxurious, and unmistakably refined.

Every detail is intentional—crafted to stand out without compromising balance or wearability.

Why Diamondboi

For over 20 years, Diamondboi has designed and handcrafted fine jewellery for clients who value quality, integrity, and timeless design.

Every piece is created with intention — balanced proportions, secure settings, and craftsmanship meant to last a lifetime.

Lab-grown vs natural, in 60 seconds

Both are real diamonds with the same optical, chemical and physical properties. The difference is origin: a natural diamond formed in the earth over millions of years and carries a rarity premium; a lab-grown diamond is grown over weeks using technology and costs considerably less for the same size and grade.

Nobody can tell them apart by eye. The only visible differences are the laser inscription on the girdle and the number on the grading report. Every diamondboi lab-grown centre diamond is IGI-certified, D–E colour and VVS2 clarity or better, and chosen for cut performance first, because cut is what makes a diamond come alive. Our natural centre diamonds are GIA-certified, E–F colour and VS2 clarity or better.

Choose natural if the story of origin matters to you. Choose lab-grown for a larger or higher-grade diamond at the same budget. Either way, the ring is made the same way, in the same studio, with the same lifetime guarantee. Read the full guide →
