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.

Before you choose
How to choose a ring
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
Treated blue diamond eternity rings are made to commission at Made With Color: one artist, one bench, in New York. Ask and we will pull stones in daylight and send passports before you decide. Stones the whole way around, no beginning, no end, no side that hides.
About treated blue diamond
Irradiated to blue and labeled exactly that way on its passport. We choose every stone loose, in daylight, and every work above carries a passport that says exactly what it is.
CHOOSING THE STYLE
On the style
Full eternity cannot be resized, only exchanged. Half eternity can, and reads identical worn.
Start with hardness
Treated 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.
Can an eternity band be resized?
A full one, no; the stones leave no metal to cut. We exchange within the first year instead. A half eternity resizes normally.
Is treated blue diamond good for rings?
Treated 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 treated blue diamond?
Treated 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.
How do these wear?
The stones underneath meet desks and steering wheels. Low bezel-set eternities are the working version.
How long until it arrives?
Ready-now works leave the studio within two business days, insured and signed for. Made to order pieces state their bench time on the page, most within three to four weeks.
