AntwerpPrecision.Sourced Worldwide.
A confidential Antwerp house supplying natural and lab-grown diamonds — alongside precious and semi-precious stones — to the world's finest manufacturers, brands, and independent jewelers.
A quiet authority in the trade’s most storied district.
From our base in Antwerp’s Diamond District, B Exclusive is built on the 29-year career of its founder, Anja Swarup — direct relationships with cutters, graders, and sight holders that let us deliver natural and lab-grown diamonds, and precious and semi-precious stones, on spec and on time.
Every parcel is sourced to the specification our clients require, accompanied by GIA or IGI certification where available, and dispatched under strict confidentiality protocols.
Four categories. One standard.
Natural Diamonds
Antwerp-sourced earth-grown diamonds in every shape and calibration. GIA or IGI certification available, cut to spec, delivered at scale.
Lab-Grown Diamonds
HPHT and CVD lab-grown diamonds with IGI certification available — identical optical and chemical properties at a competitive wholesale tier.
Precious Stones
Ruby, emerald, and sapphire sourced directly from verified origins — calibrated parcels and single signature stones.
Semi-Precious Stones
Tanzanite, aquamarine, tourmaline, morganite, spinel and more — matched and graded for large production runs.
Quiet, consistent, confidential at scale.
