Diamonds by Avi & Co. Emerald and Trapezoid Diamond Ring


Shopping for engagement rings this holiday season? There is nothing quite like the old world glamour of an emerald-cut ring. We are particularly crushing on this 14K white gold masterpiece, which showcases a 12.24 carat emerald-cut diamond at its center, flanked by two trapezoid-cut diamonds amounting to an additional carat. These precious gems are exquisite in their own right, but in combination, they remind us of a particularly influential diamond ring of the past: Grace Kelly’s engagement ring, of course!
The Hollywood star turned princess married Prince Rainier of Monaco in April of 1956, and her entire ensemble has been inspiring brides for decades since. Her emerald-cut Cartier engagement ring roasted a 10-carat central diamond and two tapered baguette-cut stones on either side (what we would now call “trapezoid”). The gorgeous style has inspired plenty of other celebrities, including Anne Hathaway, Elizabeth Taylor, Amal Clooney, and Beyonce, all of whom have rocked exquisite emerald-cut beauties.
If your special someone loves timeless glamour, Old Hollywood aesthetics, and a classic red lip, she is sure to appreciate this iconic style, available now at Avi & Co.
Diamonds by Avi & Co. Marquise Cut Diamond Statement Ring


Whether you are popping the question or simply accessorizing your outfit for that holiday gala on your calendar, Diamonds by Avi & Co.’s marquise-cut diamond statement ring is a must-have. This impeccable piece boasts a massive, 19.85-carat diamond at its center, which is flanked by an additional 0.55 carats of round-cut side diamonds, which accent the setting and band. In other words, that is over 20 carats of diamonds on your finger!
Crafted from prestigious and durable platinum, this ring is meant to make a statement. With its elongated elegance, the marquise-cut style is making a big comeback in the wedding world. Selena Gomez showed off the style in her 6-carat engagement ring given to her by now-husband Benny Blanco, and the cut’s popularity has skyrocketed since then. Our take? The marquise style is not going anywhere. It exudes taste and sophistication, and its elongated shape also helps to slim and lengthen the finger, providing a graceful aesthetic. A testament to our unparalleled craftsmanship here at Avi & Co., this marquise ring is the perfect addition to your holiday wishlist.
Diamonds by Avi & Co. Nous Trois Diamond Cuff Ring


Looking for a ring that is a little bit outside of the box? It does not get more avant garde than our signature Nois Trois ring. Showcasing three prestigious natural diamonds, the Nois Trois ring straddles the backside of two fingers, offering a floating effect as the diamonds sit on your hand. This particular ring is the perfect example of modern luxury. It highlights three exquisite stones, two pear-cut diamonds (6.19 carat and 6.83 carat) and one oval-cut diamond (5.22 carat) as well as an additional 1.45 carats of side stones that add even more sparkle to the halo settings and bands. The luminous 18K white gold craftsmanship shimmers in the light, exuding luxury and class to the maximum.
With a total diamond weight of 19.69 carats, there is no question that this ring is a masterclass in sculptural jewelry. You are sure to see plenty of eye-catching engagement rings as you go about your day, but a three-diamond creation like this one is much harder to come by. For the woman who likes her jewelry with an edge, there is no doubt that the Nois Trois ring from Diamonds by Avi & Co. is a truly prescient pick.
Diamonds by Avi & Co. Oval Cut Diamonds Toi et Moi Ring


The romance and electricity of the Toi et Moi ring from Diamonds by Avi & Co. is unmatched. We have a few different Toi et Moi options, which simply indicates that there are not one, but two showstopping gems at the center of the ring. Often, these exquisite creations are given to symbolize the connection between two partners, the experience of two becoming one. The two oval-cut diamonds in this platinum ring have a combined carat weight of 8.33. One diamond is blue and the other is white, adding an element of color and interest that is perfect for someone with a bold personality and a penchant for vibrant looks.
The history of Toi et Moi rings dates back to the late 1700s, when jewelers first had the idea of combining two major gemstones in one ring as a symbol of the union between two people. Some people opt to highlight the birthstones of each partner, while others simply pick hues or stones that they enjoy aesthetically. There is no going wrong with a Toi et Moi ring, and giving one of these as a gift sends a clear message that you love and appreciate the recipient. Not sure which Toi et Moi ring to choose? Our dedicated customer service team at Avi & Co. is here to help! We will work closely with you to find the perfect gift for that special someone.
Diamonds by Avi & Co. Eternity Band


Many diamond rings are structured around a larger central stone, but this unique and sophisticated eternity band offers a more balanced, constant look. Featuring 18 emerald-cut diamonds for a total of 9 carats, this elegant creation offers a continuous circle of sparkle perfect for symbolizing eternal love and commitment. It is also simply a great accessory! Whether you are using it as a wedding band, an engagement ring, or a jewelry box staple to liven up everyday looks, you will never regret investing in this opulent find.
The diamonds have been meticulously set in a durable, comfortable, and hypoallergenic platinum band, which ensures both beauty and longevity. Additionally, these natural diamonds are accompanied by a GIA certificate, which speaks to the quality and value of the stones and also helps them hold onto their worth should you ever sell or borrow against the ring.
