Start with three options, compare the exact listings, and choose within your budget. Each featured listing includes a grading-report link and supplier-provided image and video links. Review the report and ask about any unclear media before buying.
Measurements and ratios are supplier-reported; compare them with the grading report. More carat weight does not guarantee a larger face-up appearance or better light performance. Live stock and prices can change. This selection does not reserve a stone. Return eligibility depends on the complete order, destination and condition of the returned stone; review applicable shipping and return terms before paying.

Common questions about 3 carat plus round lab-grown diamonds
How much do 3+ carat round lab-grown diamonds cost?
Veyara currently lists 2,088 available 3+ carat round lab-grown diamonds from $590 to $73,140. Each figure is the total listed price for one loose stone, not a per-carat rate, and it moves as inventory changes.
Are these round diamonds certified?
Every stone featured on this page links to its grading report from the issuing laboratory — IGI or GIA — alongside supplier-provided media links. Media links alone do not independently verify the identity of the pictured stone; ask us to confirm any unclear details before buying. The report number is listed on the stone page so you can verify it with the laboratory directly.
Does the listed price include a setting?
No. The listed total buys one loose lab-grown diamond. Settings, mounting and assembly are separate, so you can set the stone with your own jeweler or ask Veyara to quote the work.
What shipping and returns apply to a round diamond order?
The terms that apply depend on the exact stone and order. Current shipping, delivery and return terms are published at https://veyaradiamonds.com/shipping-returns and are shown again on each stone's listing before payment.
