At Allum & Sidaway, we believe you really can have it all — quality and quantity. We’re proud to introduce the newest addition to the A&S family: our Laboratory-Grown Collection. This curated collection brings together timeless elegance and modern style. Every design and stone is thoughtfully selected by our in-house bespoke team, capturing everything a diamond is meant to embody… perfection.

Add a pop of colour and a dash of elegance with this stunning three-stone ring, featuring a cushion-cut blue diamond in a sleek claw setting, flanked by two sparkling round diamonds—all set in platinum for a truly eye-catching look. With their soft, rounded corners and larger facets, cushion-cut diamonds have been turning heads since the 17th century. See below for full diamond details.
