Diamonds come in a wide variety of shapes and styles, making choosing the perfect diamond for your special someone a monumental task. Which option best matches their unique personality and shows off their sophisticated style? While diamond shapes and cuts are two different categories, we will be combining these two modes of diamond decision-making in order to provide a comprehensive list that might just inspire you when you are looking for the precious gemstone of her dreams. Shop these looks and more at Avi & Co. today.
January: Cushion Cut Diamonds
For those with wintertime birthdays, a cushion-cut diamond perfectly matches the brilliance and sparkle of sunlight on snow. Cushion-cut diamonds are popular in jewelry, known for their rounded corners combined with overall geometric lines. They exude brilliance and romance, signifying femininity with a graceful and timeless silhouette no matter the time of year. Better yet, embrace January’s birthstone in your jewelry as well and incorporate blood-red garnets into a meaningful piece of jewelry alongside a cushion-cut diamond.
February: Heart-Shaped Diamonds
The month of Valentine’s Day would not be the same without an exquisite heart-shaped diamond to steal the show (and her heart, of course). Heart-shaped diamonds are romantic and whimsical, offering a playful statement cut that adds levity and flirtation to any outfit. Nothing says love like this canonical shape, which is ideal for earrings, necklaces, and other types of jewelry that truly allow the heart shape to make a big impact.


March: Baguette Diamonds
Baguette diamonds show off a stunning geometric shape that is common in luxury watches as well as high-end jewelry. They are excellent for setting into timepieces as well as bracelets, necklaces, and more, as their square corners make them easy to set in great numbers. The elongated, baguette shaped diamonds carry a sense of pragmatism and togetherness. They are perfect for sleek, chic urban style and those who favor a more dramatic color palette.
April: Floral Diamonds
The month of April ushers in springtime, and it is only right to celebrate with diamonds that evoke rebirth and renewal themselves. Diamonds are typically not cut into floral patterns, but often, different shapes are combined to create the appearance of a flower-inspired cut. As the diamond is April’s birthstone, celebrating this special month with a variety of different cuts combined into one striking piece of art is the ideal nod to tradition. Additionally, the birth flower for the month of April is the daisy, an iconic floral shape if there ever was one.


May: Emerald Cut Diamonds
Celebrate the birthstone for the month of may, the stunning green emerald, with diamonds that evoke the standard cut for this precious and rare gem. Emerald cut diamonds are known for their bold, sleek lines and what is often dubbed the “hall of mirrors” effect. The emerald cut is less famed for sparkle, instead prioritizing clarity, symmetry, and quiet sophistication. The rectangular shape with cropped corners is excellent for all different kinds of jewelry; you will see this shape just as often in bracelets as you will in engagement rings or necklaces.


June: Radiant Cut Diamonds
Radiant cut diamonds are perfect for those born during the sunny summer months, like June, as they combine the sparkle of a brilliant-cut diamond with the geometric clean lines of an emerald-cut stone. Radiant-cut diamonds are typically rectangular or square with cropped corners and are cut to catch the light as much as possible. It is also one of the most brilliant options of the rectangular shapes, with 70 facets that some describe as a “crushed ice” effect. This also makes radiant-cut diamonds more forgiving when it comes to inclusions and color than step-cut diamonds like emerald or Asscher cuts.
July: Princess Cut Diamonds
A popular contemporary cut that has modern appeal, the princess cut is perfect for the exuberant, lively character of July. For the late Cancers and early Leos on the astrological calendar, a princess cut diamond showcases fun-loving personalities and a bubbly social scene. It is made for those who are thrilled to show off a striking engagement ring, turn heads in a memorable pendant, or make a subtle statement in glamorous stud earrings. Princess cut diamonds have sharp corners and clean lines, and their square shape is timeless and chic.
August: Oval Cut Diamonds
These brilliant cut diamonds are made for the late summer heat and nine o’clock sunsets that make August one of our favorite months of the year. They exude graceful ease, effortless elegance, and stunning light refraction that is truly difficult to top. Its elongated shape flatters the hand, making fingers look longer and slimmer when worn set in an engagement ring. Additionally, the lengthy silhouette offers the appearance of even more carat weight. Oval cut diamonds are a stunning reflection of modern style that we suspect will continue to dominate engagement and jewelry styles for years to come.


September: Asscher Cut Diamonds
The vintage allure of the Asscher cut speaks to those born in September, the Libras and Virgos of the astrological calendar. It exudes symmetry, class, and sophistication. Like the emerald-cut diamond, it is a step-cut stone with a more geometric, clean look than a brilliant-cut gem. The Asscher cut was particularly popular during the 1920s Art Deco era, and is coming back in style as that chapter of fashion history regains popularity. Asscher cut diamonds often display a string X pattern when viewed from above, which adds to their one-of-a-kind intrigue. The September birthstone is a sapphire, but an Asscher cut diamond conveys the same sense of history, prestige, and grandeur that she deserves.
October: Marquise Diamonds
Elongated with pointed ends, marquise diamonds offer an elevated and unexpected statement that is perfect for those born in October. Marquise diamonds are an excellent way to maximize carat weight, as their elongated silhouette makes the diamond appear larger than a round diamond of the same weight. The length of the marquise cut may also have a slimming effort on the finger. Marquise diamonds exude royalty, antiquity, and endless taste. Celebrities like Selena Gomez have said yes to marquise-cut diamond rings, and these stunning stones project a sense of mystery, intrigue, and vintage style.


November: Pear Cut Diamonds
The pear cut diamond is a popular choice with autumnal undertones and plenty of celebrity inspiration to draw from. Silver screen stunner Margot Robbie opted for a pear-cut engagement ring set in a stunning rose gold band. The pear shape combines the graceful curves of a round diamond with a touch of the marquise cut’s dramatic flair. They offer exceptional sparkle and fire, making them one of the most desirable cuts on the market today. Their versatile shape also lends itself to both modern and traditional setting options, meaning you can personalize a stunning pear cut stone to her exact preferences and specifications.
December: Round Diamonds
Perhaps the most traditional of the diamond cuts discussed in this article, round diamonds are perfect for those born during the holiday season. They highlight tradition, laughter, light, and a playful brilliance that evokes frost on windowpanes and presents wrapped under the Christmas tree. Like holiday cheer, round diamonds will never go out of style. They look just as exquisite set on a stunning engagement ring as they do on a staggering solitaire pendant setting. Round diamonds can be paired with all colors of gold as well as platinum or anything else she prefers.
