Colored Diamond Rings for Women
Most diamonds are bought for having as little color as possible. A fancy color diamond is the opposite: the color is the point. Our pink, yellow, blue and green diamonds are lab-grown, which puts saturated colors within reach that would cost a fortune as mined stones. Our black diamonds are natural. Every fancy color diamond of 1 carat or more comes with an IGI grading report.
Natural or Lab-Grown: What We Use
It helps to know this before you start browsing.
- Pink, yellow, blue and green diamonds in our rings are lab-grown. They are real diamond, grown in a laboratory, with the same hardness as a mined stone.
- Black diamonds in our rings are natural, meaning mined.
Natural pink, blue and green diamonds are among the rarest gems in the world, and the strongest colors sell for prices few people would put into a ring they wear every day. Lab growth makes the same hues available in sizes and saturations that suit an engagement ring or an everyday piece.
Shop by Color
Pink
Pink ranges from a pale blush to a deep, rosy tone, and it suits rose gold especially well. See pink diamond rings.
Yellow
Yellow runs from soft lemon to a strong canary color. Setting a yellow diamond in yellow gold makes the color look richer, because the metal reflects into the stone. See yellow diamond rings.
Blue
Blue goes from pale sky to deep ocean. White gold keeps it crisp and cool, and yellow gold gives a striking contrast. See blue diamond rings.
Green
Green is the least expected of the four, and it works well in elongated shapes such as pear and marquise. See green diamond rings.
Black
Black diamonds are opaque, so they show a glossy, mirror-like surface instead of sparkle. They suit bold, modern designs and pair well with white diamonds for contrast. Ours are natural stones. See black diamond rings.
How Colored Diamonds Are Graded
A colorless diamond is graded on how little color it has. A fancy color diamond is graded on the color itself, using three terms.
- Hue: the color family, such as pink or blue, including any secondary color (a "purplish pink", for example).
- Tone: how light or dark the color is.
- Saturation: how strong or pure the color is.
These combine into an intensity grade. The scale used by the major labs runs from Faint, Very Light and Light, through Fancy Light and Fancy, up to Fancy Intense and Fancy Vivid, with Fancy Deep and Fancy Dark for darker stones. Fancy Intense and Fancy Vivid are the strongest and most sought-after grades.
Cut and clarity still matter, but less than for a colorless stone. Many colored diamonds are cut to concentrate color rather than to maximize sparkle, which is why radiant and cushion shapes are common.
What Gives a Diamond Its Color
In nature, color comes from tiny changes in the diamond's makeup:
- Yellow from nitrogen atoms in the crystal.
- Blue from boron.
- Green from natural radiation over long periods.
- Pink from distortion in the crystal structure, which is not fully understood.
Lab-grown colored diamonds use the same chemistry. Nitrogen or boron can be added while the crystal grows, and some colors, often pink and green, are produced or deepened by treatment after growth. An IGI report notes the diamond's origin and any treatment it identifies. Our lab diamonds buying guide and how diamonds are made explain the growth process in more detail.
Certification
Any single fancy color diamond of 1 carat or more in our rings is certified by IGI. The report gives the carat weight, the color description and intensity grade, the clarity, the measurements, and the fact that the stone is laboratory grown.

Colored Diamond Engagement Rings
A colored center stone is a clear break from tradition, and lab growth means the stone can be large and strongly colored without a museum price. Pink and yellow are the most common choices, and a halo of white diamonds makes the center color stand out more. See colored lab diamond engagement rings and our colored diamond engagement ring buying guide.

Choosing the Gold
Metal color changes how a colored diamond looks more than it changes a white one.
- Yellow gold warms and deepens yellow stones, and contrasts strongly with blue and green.
- Rose gold flatters pink.
- White gold keeps blue, green and black looking cool and clean.
Our guide to gold colors shows the options side by side.

How to Choose
- Pick the color. Start with the one you are drawn to, then look at a few intensities of it.
- Decide on intensity. Fancy Intense and Fancy Vivid show strong color. Lighter grades are softer and more subtle.
- Choose the shape. Radiant and cushion cuts tend to hold color well. Pear and marquise suit green and pink.
- Set the size. If you want an IGI report, choose a fancy color stone of 1 carat or more.
- Choose the gold. Use the pairings above.
- Confirm the ring size. Measure with our size guide, and check the returns and exchange policy in case the fit is off.
For cleaning, see the care guide. If you have a specific color and shape in mind that is not in the collection, ask about a custom design.
