Two-Tone Diamond Halo Engagement Ring

This is a contemporary two-tone diamond engagement ring, featuring a center-set round brilliant cut diamond. The ring is constructed with a mixed-metal design, likely 14k or 18k white gold for the primary band and yellow or rose gold for the stylized basket setting. The center diamond is held by four yellow gold prongs and sits above a unique semi-halo or 'hidden halo' of melee diamonds encircling the base of the basket. The white gold shank is heavily embellished with micro-pavé set diamonds that run down the shoulders of the band in a double or triple row formation. Inside the band, there is a visible laser-engraved hallmark or serial number ending in '1924', which could indicate a designer touch or a certification tracking number. The overall craftsmanship displays high-end commercial quality with precise stone setting and a polished finish. The condition appears excellent with minimal surface scratches on the lower shank. The design aesthetic is modern and opulent, characterized by the 'hidden halo' trend popular in the 2010s to 2020s. No major chips or inclusions are visible to the naked eye in the center stone from this profile view.
