10 Carat Oval Lab-Grown Diamond Rings
A long oval that fills the finger. These 10 carat oval diamond rings come with the lab-grown oval seated and the price already accounting for it. Platinum or any of the golds is your first pick; next comes the shank, plain and rounded, studded with pavé at the shoulders, or with a hidden halo cradling the stone.

Ten carats on the hand
An oval at this weight measures well past half an inch end to end and reaches across a good share of the finger below the knuckle. Its elongated line pulls the eye lengthwise, so even a stone this large keeps the hand looking slim. Grown in a lab, a ten-carat oval costs a small slice of what a mined one of equal weight would.
Shank options
- Plain rounded: the oval carries the ring alone.
- Pavé shoulders: extra glitter near the head while the outline stays clean.
- Hidden halo: a tucked ring of lab-grown diamond accents beneath the oval, visible from the side.
Metal beneath a big oval
Platinum, the heaviest option here, loses metal very slowly, a sound base for prongs gripping a heavy stone. White gold offers the same cool tone at a lower cost, while yellow and rose gold wrap the oval in warmth. Shanks run roughly 1.8–2.5 mm.
Daily life with a ten-carat stone
A tall head snags on sweaters and bumps door frames, so leave the ring off at the gym, for cleaning and on travel days. Check the prongs every few months; a jeweler can retighten them before the oval shifts.
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.
