8 Carat Oval Lab-Grown Diamond Rings, grown in light.
Eight carats, drawn out in an oval. These rings ship with an 8-carat oval lab-grown diamond mounted, one figure covering metal and stone. The elongated outline gives generous face-up size for the weight. On the product page you choose platinum or white, yellow or rose gold, plus a bare, pavé-shouldered or hidden halo shank.

Scale of an 8-carat oval
An oval of this weight commonly runs about 17 mm long and fills much of the gap between knuckles. That presence is the reason to choose it, and a narrow shank keeps the ring in proportion; widths here span roughly 1.8 to 2.5 mm.
Three ways to frame it
- Bare shank: the oval stands alone and seems longer still.
- Pavé shoulders: lab-grown diamond accents add glints right beside the stone.
- Hidden halo: a concealed row beneath the oval that sparks when seen from an angle.
Choosing the metal
For an 8 carat oval engagement ring, platinum keeps prongs tight and softens to a gentle sheen instead of thinning out. White gold looks much the same and stays bright with a fresh rhodium coat now and then. Yellow and rose gold bring warmth around a colorless stone.
Wearing it every day
A broad, high oval meets door frames first, so park it during sport, scrubbing and planting. A weekly bath in lukewarm sudsy water and a toothbrush under the stone lifts the haze that dims a big oval. An annual prong inspection is time well spent.
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.
