Den Ultimative Diamantguide
Our sourcing approach
We work with long-standing partners in Antwerp, selecting each diamond by hand. Every stone is reviewed by our gemology-trained team—not just for its certificate, but for how it looks and feels in person.
If your design includes multiple stones, we hand-pick side stones or have them cut to match—because harmony matters.
We look for balance, beauty, and long-term quality—stones that hold their own, both in the moment and over time.
Honest advice when buying diamonds.
At ByLamm Diamonds, we take a considered approach to diamond buying—whether you're sourcing a diamond for a bespoke engagement ring or looking for something with long-term value. We believe it should feel exciting, not overwhelming.
We offer private consultations and personal guidance, helping you understand what matters most—clarity, colour, cut, and carat—but also proportion, light, and how a stone will live in the design. Whether you're new to diamonds or already know what you want, we’re here to simplify the process and offer advice. You will always be presented to a selection of diamonds or gemstones from which we will help you decide.
