Colored Diamond Necklaces for Women
Each necklace here holds one diamond in a strong color: pink, yellow, blue or green, in round, oval, pear, emerald, radiant or heart shapes. The stones are lab-grown and then color-treated, and they come at 1, 2 or 3 carats, with larger sizes made on request. One stone, set alone at the neckline, is the simplest way to wear a fancy color.
Why One Stone Holds the Color
In a cluster or a line of small diamonds, color gets diluted: each stone is too small to hold much depth, and the white sparkle between them softens the shade. A single larger stone concentrates it. That's why our colored necklaces are all solitaire pendants, most of them in a bezel that frames the stone in a thin rim of metal.
Size changes how strongly the color reads. At 1 carat, a pink or blue pendant is a quiet touch of color that sits easily under a collar. At 2 carats, the shade becomes the first thing people notice. At 3 carats, roughly 9 mm across for a round, the stone carries the whole outfit. If you want something larger still, our custom design team can make it to order.
Pink With Grays and Navy
Pink looks richest against cool, muted clothing: charcoal, heather gray, navy and black all make it glow by contrast. With a pastel top, it can blend in, so pair a soft pink stone with a darker neckline or a crisp white shirt. Rose gold makes pink look warmer and more romantic; white gold keeps it bright and modern. If you already wear a rose gold ring or watch, matching the metal ties everything together. The full range is in our pink diamond necklaces.
Where Yellow Looks Warmest
Yellow is the easiest color to wear with gold jewelry you already own, since a yellow gold bezel makes the stone look even sunnier. It stands out against white, cream, olive and camel, and looks natural with denim. Under warm indoor light it deepens toward canary; in daylight it reads brighter and lighter. A yellow pendant also layers well with plain gold chains, which echo its warmth without competing. Every shade is in our yellow diamond necklaces.
Blue Next to White and Black
Blue is the coolest of the four, and it looks sharpest against white, black and gray, or with a simple black evening dress. White gold or sterling silver flatters it most, keeping the tone icy rather than letting a yellow rim warm it toward green. A blue pendant also pairs well with white diamond studs, because both read as cool, bright stones. Browse every design in our blue diamond necklaces.
Green and Earthy Colors
Green is the least common color in diamond jewelry, which is much of its appeal. It suits cream, tan, rust, chocolate and other earthy tones, and looks fresh against white linen. Yellow gold gives green a warm, vintage feel; white gold makes it look cooler and closer to mint. Because the color is unusual, a green pendant is usually worn on its own, with simple white or gold earrings. More are in our green diamond necklaces.
The Rim Around the Stone
On a bezel pendant, the metal touches the edge of the diamond all the way around, so its color reflects into the stone. A yellow gold rim adds warmth to any shade, white gold or silver adds brightness, and rose gold adds a pink cast. That makes the metal choice part of the color choice: the same blue diamond will look slightly different in yellow gold than in white gold. All our colored pendants come in 925 sterling silver and in 10K, 14K or 18K yellow, white or rose gold.
Grown, Then Colored
These diamonds are grown by CVD and then given their color through a treatment after growth, which each product page states. Because every stone is at least 1 carat, each one comes with an IGI grading report that identifies it as laboratory-grown and notes the color treatment. A GSI jewelry certificate is added to any pendant priced above $800. Some pendants arrive with the chain attached, and on others you choose a chain in silver, 14K or 18K gold; 10K pieces come without a chain.
To build a set in one color, match your pendant with colored diamond earrings, colored diamond rings or colored diamond bracelets, or explore everything in our colored diamond jewelry collection.
