Moval Lab DiamondMilgrain Bezel, Graduated Cigar Band, Cathedral

Design Intent

This design is the definition of refined restraint with a vintage accent. A moval centre diamond — an elongated oval with softly pointed ends, sitting between an oval and a marquise — is framed by a full bezel finished with a fine milgrain edge for a clean, heirloom feel.

The graduated cigar shank tapers from 4.00MM at the shoulders to 2.50MM at the base, keeping the band intentionally minimal so the centre diamond remains the focus. A cathedral profile lifts the bezel, and an open petal gallery beneath it lets light reach the diamond from the sides — timeless, confident, and effortlessly sophisticated.

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.

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 →
