Before you choose
How to choose a ring
Start with the hand, not the stone
Long fingers carry tall settings; working hands want a bezel or a low prong. If you wear gloves or type all day, height is the first decision, not the last.
Pick the stone for the life it will live
A ring worn daily needs 8 or harder on the Mohs scale: sapphire, spinel, diamond. Softer stones like opal and emerald are occasion stones, or need protective settings.
Size in the afternoon
Fingers run a half size larger by evening and in summer. We size to your afternoon measurement and resize free within two sizes.
Buy the cut, not the carat
A well-cut smaller stone reads larger and livelier than a lazy big one. This is where our money goes, and where yours should.
The short answer
Marquise lab-grown blue diamond rings at Made With Color: one one of a kind work at $6,480, each built around a stone chosen loose, in daylight, in New York. Blue diamond grown above ground, same boron, honest price. Every stone ships with a passport naming origin, carat, cut, and any treatment in plain words. The longest face-up spread of any cut, points at both ends.
About lab-grown blue diamond
Blue diamond grown above ground, same boron, honest price. We choose every stone loose, in daylight, and every work above carries a passport that says exactly what it is.
READING THE CUT
On the cut
Length-to-width near 2:1 reads classic; check both points are prong-guarded.
Start with hardness
Lab-grown blue diamond is 10 / 10 on the Mohs scale. Hard enough for daily wear in any setting, including rings.
Fit before beauty
Measure a ring you already own at the end of the day, when fingers run largest.
Then the look
Decide setting height first. Hands that type, garden, or lift want the stone low.
Is marquise coming back?
It never fully left; it cycles. What matters is the hand: marquise lengthens fingers like no other cut.
Is lab-grown blue diamond good for rings?
Lab-grown blue diamond is 10 / 10 on the Mohs scale. A ring takes more knocks than any other jewel. Below 8 on the Mohs scale, choose a bezel or a low setting.
Which birthstone is lab-grown blue diamond?
Lab-grown blue diamond is the Apr birthstone and the traditional stone of the 60th anniversary. We set it for both, and for no occasion at all.
Are these stones treated?
Untreated unless the passport says otherwise. When a stone of ours is heated or grown in a lab, the passport says so in that word, in the same type size as everything else, and the price reflects it.
