1.5 Carat Round Lab-Grown Diamond Rings
The familiar circle, scaled up a step. A 1.5 carat round lab-grown diamond ring shows a broader face than a one-carat stone while keeping the outline everyone recognizes. Novara mounts the round at the bench, and its cost is already inside the listed figure. Pick a 1 1/2 carat round solitaire, pavé shoulders or a hidden halo, and then the metal.

Why rounds throw so much light
A round brilliant carries 57 or 58 facets angled to bounce light back out through its table, giving it more fire than any fancy shape. Those facets also disguise faint tint and tiny inclusions, and a circular girdle has no points to snag knitwear, so a wedding band can rest right beside it.
Ways the round is held
- Plain-shank solitaire: the round has the stage to itself, and the shank stays sleek under the fingertips.
- Pavé shoulders: a short trail of lab-grown diamonds walks the eye toward the round.
- Hidden halo plus pavé shank: a ring of melee under the round brightens its profile.
Gold in three colors, or platinum
White gold and platinum give a frosty, bright frame. Yellow gold leans warm and a little nostalgic, while rose gold brings a pinkish glow that flatters warm complexions. Platinum outweighs all three and gradually takes on a brushed, matte character with wear.
Keeping a round center bright
The pavilion underneath gathers more film than anywhere else, and a clouded pavilion makes the whole round look sleepy. Once a week, scrub beneath it with lukewarm suds. When a wedding band joins it, make sure the pair lines up so the metals do not grind together.
Ring questions, answered.
How do I choose an engagement ring?
Start with the shape she loves, then the setting style. Our gemologists can help you balance carat, cut and budget on a free video call.
Can I build my own engagement ring?
Yes — pick a setting, then a diamond, and review the finished ring before it goes to the bench.
Does the diamond price include the setting?
Diamond and setting are priced separately in the ring builder, and the total is shown before you add the ring to your bag.
How do I find my ring size?
Use our ring size guide, or order a free ring sizer — it arrives in 2–3 days.
Can I return or resize my ring?
You can return it within 30 days (a 10% restocking fee applies to resized or engraved pieces), and your first resize within 60 days of delivery is free.
Should I insure my engagement ring?
We recommend it. Every ring ships fully insured; once it is yours, a separate jewelry insurance policy covers loss, theft and accidental damage.
