1ct lab-grown diamonds explained
A 1ct diamond is the classic engagement size — balanced, versatile and clearly visible on the hand. Carat is weight, not size — how large a 1ct diamond looks depends on its cut and shape, so two 1ct stones can face up quite differently. Use the "see it true to size" tool on any product to judge the real face-up dimensions on a finger.
Every diamond here is lab-grown — a real diamond with the same carbon crystal structure, hardness and fire as a mined stone, created above ground in a matter of weeks rather than extracted over millennia. Because origin is the only difference, you typically pay 60–80% less than the mined equivalent for the same look, and every stone is conflict-free and traceable.
Getting the most from a 1ct diamond
- Favour an excellent cut — a well-cut stone looks bigger and brighter than a poorly cut one of the same weight.
- Elongated shapes (oval, marquise, pear) tend to look larger than round for the same carat.
- Stay eye-clean — VS clarity or better keeps the stone flawless to the naked eye.
- Set your budget by the 4Cs together rather than chasing carat alone.
Each stone is independently certified by IGI or GIA, hand-inspected and photographed by our team in Sweden before dispatch, and shipped fully insured with free delivery and 30-day returns. Every diamond is one of a kind — the exact stone you see is the stone you receive, ready to wear loose or set into a ring with help from our gemologists.
Questions, answered
What 1ct diamonds do you offer?
Our 1ct diamonds selection features 225 certified lab-grown diamonds in stock right now, each independently graded by IGI or GIA and hand-inspected in Sweden before it ships.
Are lab-grown diamonds real diamonds?
Yes. A lab-grown diamond is a real diamond — chemically, physically and optically identical to a mined one. The only difference is origin: it is grown above ground in a matter of weeks instead of mined over millennia, typically 60–80% less than the mined equivalent.
How are your diamonds certified?
Every stone is independently graded by IGI or GIA and ships with its certificate. You can verify the report number directly on the lab's public website.
Are these diamonds conflict-free?
Yes. Because they are lab-grown, our diamonds are entirely conflict-free and traceable, with a far lower environmental footprint than mined stones.
Can I return a diamond or set it in a ring?
Yes. Every order includes free insured shipping and 30-day returns. Each stone is loose and ready to set — choose "Set this stone in a ring" on any product and our gemologists help you build the setting.
