Astrid – Yellow Cushion-Cut Lab-Grown Diamond Ring
A captivating expression of colour and contemporary elegance, Astrid is a yellow lab-grown diamond engagement ring featuring a magnificent 3.03ct cushion-cut centre diamond.
Its vibrant yellow hue brings warmth and individuality to this distinctive design, while the softly rounded corners and brilliant faceting of the cushion cut create a beautiful interplay of light and sparkle.
Crafted in 18kt yellow and white gold, Astrid combines the richness of yellow gold with a contrasting white gold setting that beautifully frames the centre diamond. The refined silhouette allows the gemstone's colour and brilliance to take centre stage.
Inspired by the Scandinavian name associated with beauty and grace, Astrid celebrates individuality through a timeless yet contemporary design.
Whether chosen as a distinctive engagement ring or a meaningful statement piece, Astrid offers a beautiful alternative to traditional white diamond jewellery, designed to be treasured for years to come.
