Colorless SI diamonds: what the grade means
SI clarity is eye-clean and offers the best value. This tier is chosen to look bright and clean to the eye while keeping excellent value — the sweet spot where a higher grade would cost more without a visible difference.
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.
Why this quality tier
- Eye-clean — no inclusions visible without magnification.
- White face-up — no warmth to the naked eye, even set in white gold or platinum.
- Better value — you spend on the grades that show, not the ones only a loupe reveals.
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 colorless si diamonds do you offer?
Our colorless si diamonds selection features 243 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.
