A big oval,
you never have to baby.
The Penumbra Bezel Set Engagement Ring by Goodstone centres a breathtaking 4.51ct lab-grown oval diamond in a sleek bezel that keeps it secure and snag-free. Bold and statement-making, yet completely livable — and ethically grown.
For the woman who wants
drama and practicality.
This is the one I pull for someone who dreams of a big centre stone but doesn’t want to fuss over it. The bezel means she gets serious presence and total peace of mind — nothing to snag, nothing to worry about.
She cares about doing it responsibly too, so a large lab-grown diamond that delivers the wow without the mined-stone weight is exactly right.
Three things that make it
a showstopper.
A 4.51-carat oval centre
A secure, snag-free bezel
Ethically grown
About Goodstone.
Goodstone is known for lab-grown diamond engagement rings that pair serious size and quality with modern, customisable design and a responsible approach. The Penumbra is a great example — a bold bezel-set oval, ethically grown and built to impress.
A statement stone that’s
built for real life.
The bezel setting is the practical hero — it protects the big oval and keeps the profile smooth, so despite the size there’s nothing to snag. Diamonds are the hardest material there is, so it stands up to daily wear; a large stone just appreciates an occasional wipe to stay dazzling. Get her size right, and it’s a forever ring.
