Forma Engagement Rings

About this collection

Forma pairs lab-grown diamonds with broad, flat cigar bands for a bold engagement ring silhouette. Compare the geometric outline of the Asscher ring with the curved centre of the oval ring, or explore other diamond shapes below.

Each ring is made to order in your chosen gold colour and purity, with diamond size and colour/clarity options. Confirm your ring size, final specifications and production timing with our team. Browse all engagement rings or discuss a custom design.
