Panastara Diamond Guide
1.5 Carat Lab-Grown Diamond Rings
A 1.5 carat centre stone gives noticeably more presence than 1 carat while staying versatile for everyday wear. Explore solitaire, halo, hidden-halo and shoulder-set designs across the most popular diamond shapes.
A high-impact middle ground
For many buyers, 1.5 carats is the point where a centre diamond feels substantial without moving into the scale of a 2 or 3 carat stone. Shape and proportions still determine how large the diamond looks on the hand.
Compare the complete specification
Look beyond carat weight. Cut, dimensions, colour, clarity, fluorescence and certification all affect what you see and what you pay. A well-proportioned stone can outperform a heavier stone with poorer proportions.
Certification and hallmarking
Panastara pieces are made to order. Where a centre stone is sold as IGI certified, an independent IGI grading report accompanies the diamond. Pieces that fall within UK hallmarking requirements are hallmarked before delivery.
