Diamonds by Avi & Co. Jewelry Collection
Avi & Co.’s fine diamond jewelry collection is like no other on the market today. We have been in the luxury watch and jewelry business for decades, during which we have gained experience and industry connections that have allowed us to design and obtain incredible pieces of jewelry that you will not find anywhere else. At our flagship store in Manhattan, you can explore our full collection of breathtaking jewelry for yourself.
What sets Diamonds by Avi & Co. apart from pieces you might find elsewhere? Our diamond jewelry is crafted with the finest precious metals and naturally mined, GIA-certified diamonds. But most of all, we are not afraid to show off when it comes to size, or more specifically, carat weight. As you may know, diamonds are described according to four criteria:
- Cut: The shape of the diamond, for instance oval, round, emerald, or Asscher.
- Color: The hue of the diamond. While most people imagine opaque or translucent stones when they think of diamonds, these gems can have subtle or noticeable coloring in shades of yellow, pink, blue, or brown.
- Clarity: The level of transparency of the diamond. Is it truly clear? Does it have imperfections, and exactly how microscopic are they? Clarity is graded on a scale with 11 grades, ranging from “flawless” (FL) to “included” (I1 to I3).
- Carat: The weight of the diamond, which is an indication of its size.
At Avi & Co., we do not shy away from largesse and opulence when it comes to the carats of our diamonds. We sell engagement rings with center stones over and approaching 20 carats (the average engagement ring diamond in the USA is just 1.2 carats) and tennis bracelets shimmering with nearly 40 carats of diamonds. Our pieces are made for those who want to embrace the finer things in life, those who know they deserve only the best of the best and would never settle for anything less. If you are looking for a truly show-stopping diamond, you shop at Avi & Co.


Our jewelry collection includes rings, bracelets, necklaces, earrings, and eye-catching statement pieces in each category. We sell both translucent and fancy diamonds, meaning you can find extremely unique pieces that complement your own personal style without worrying about wearing the same necklace as one of your friends. Each piece of jewelry at Avi & Co. is truly one of a kind.
What Are Fancy Diamonds?
All diamonds are fancy, right? In the traditional sense of the word, absolutely. But when it comes to diamonds, the word fancy actually means a diamond with coloring outside the typical range.
Recall that color is one of the four criteria according to which diamonds are described. The traditional diamond color scale accounts for stones on a gamut of translucent to pale yellow, which are labeled using letters D through Z.
Fancy diamonds exist outside this rating system and exhibit unique and vibrant hues like brighter yellows pink, blue, and even green. These stones are less traditional and, in many cases, are extremely rare and unique, especially in larger carat weights.
Fancy diamonds in hues of green, red, orange, and purple are extremely rare. There are very few examples of diamonds in these colors with carat weights large enough to make into jewelry. Diamonds with pink, blue, black, or white coloring are considered rare and highly valuable as well, but they are prevalent enough to be mined and used for jewelry on a regular basis. Some unusually large stones in these colors have been made into famous gems: The Black Orlov diamond, named after a Russian princess, is a whopping 67.5 carats.
Yellow and brown diamonds are considered the most common among fancy diamonds, but they still amount to a relatively small percentage of jewelry when compared with their translucent counterparts. Brown diamonds, also nicknamed “chocolate diamonds,” can be relatively affordable. Yellow diamonds, however, maintain a higher level of status and are frequently seen in high-class jewelry and pieces created with a more vintage look in mind. Because of their rarity and luminosity, yellow diamonds are a favorite of many jewelers around the world.
Our Favorite Fancy Diamond Jewelry Pieces
At Avi & Co., we are proud to use naturally mined fancy diamonds in some of our jewelry pieces. These elite stones are incredibly rare and add an element of intrigue to what might otherwise be a more traditional piece of diamond jewelry. Here are some of our favorite pieces that are currently available, which showcase the beauty of rare fancy diamonds.
Fancy Yellow Diamond Cushion Cut Bracelet


This gorgeous tennis bracelet features 31 vibrant fancy yellow diamonds, which perfectly complement the 18K yellow gold used to create the bracelet itself. One of the reasons we love yellow diamonds is the warm, almost buttery effect they offer, especially when paired with a warmly toned metal like this one. With over 30 carats of fancy diamonds, this bracelet is sure to turn heads at your next event. Even so, it is also perfect for elevating your everyday style.
Fancy Pink Diamond Cushion Cut Engagement Ring


This totally unique pink diamond engagement ring is to take her breath away. A sizable 7.27-carat cushion cut pink diamond is the star of the show, surrounded by another 1.14 carats of smaller stones on the halo and the band. Crafted from a blend of platinum and 18K rose gold, this ring shows off a harmonious contrast between the cool metal and the rosy hues of the center stone. A one-of-a-kind piece that perfectly encapsulates love and luxury, this ring is meant for the woman who is a leader, not a follower.
Fancy Yellow Diamond Heart Drop Earrings


Unlike the tennis bracelet shown above, these striking earrings showcase both fancy yellow diamonds and the more traditional translucent stones. Yellow diamonds complement their colorless counterparts seamlessly, making for a more unique and versatile earring that allows jewelers to truly unleash their creativity. These earrings showcase heart-shaped yellow diamonds suspended beneath translucent pear-shaped diamonds, creating an overall effect of elegance and prestige. With a combination of platinum and 18K yellow gold, the metal is both warm and timeless, picking up the shimmer of these gorgeous stones.
Fancy Pink Diamond Oval Halo Engagement Ring


Let your newfound love for rare, pink diamonds show with this one-of-a-kind engagement ring in a staggering 20.53 carat weight. This is an absolutely show-stopping diamond that goes above and beyond even the stones that European royalty wear: This pink diamond ring has a full 8.5 carats on Kate Middleton’s oval cut sapphire, which is just 12 carats in comparison. The center stone is encircled by a dazzling halo of another 1.75 carats of diamonds. Crafted from platinum and 18K rose gold, the precious metals offer a striking contrast as well as the durability and longevity you need in a ring that symbolizes your lifetime of love.
