Lab-Grown Diamond Engagement Ring
When light catches the sharp, architectural facets of the 9 x 9 mm Asscher cut, it reveals a quiet geometry that feels both intimate and deliberate. This semi-set engagement ring foundation in warm 18K rose gold invites the addition of a center stone, framed by four delicate side stones that enhance its vintage-inspired clarity.
Handcrafted in our Williamsburg studio, the band’s smooth finish and low-profile setting ensure a comfortable fit for daily wear, while the rose gold’s subtle blush complements a range of skin tones. Each prong is meticulously shaped to cradle your chosen diamond securely, balancing strength with refined elegance.
Our commitment to lab-grown diamonds means your ring will carry the brilliance of tradition with a modern ethical edge, minimizing environmental impact without sacrificing beauty.
Ideal for those who appreciate architectural detail and a romantic silhouette, this five-stone semi-set suits slender to medium finger sizes and layers gracefully with wedding bands or stackable rings. Its low profile makes it glove-friendly and unobtrusive for everyday life.
Should you need resizing or wish to explore custom stone options, our Brooklyn studio offers personalized consultations to guide you through every step.
