Oval lab grown diamonds are quickly becoming one of the most popular options for today’s fine jewelry, particularly oval diamond engagement rings. With their elongation and faceting that produces fire and sparkle, oval diamonds have a brilliant combination of elegance and presence because they appear larger than their actual carat weight. It really doesn’t matter if you are looking at a 1 carat oval diamond ring or you are being dazzled by a 3 carat oval diamond ring, the oval shape definitely has a presence and appearance beyond its carat weight.
In this guide, we'll dive into why oval diamonds are so popular, how to choose the right length-to-width ratio, and our expert tips for avoiding the bow-tie effect—a common concern for anyone purchasing an oval. We’ll also show you how the oval's beauty extends beyond rings, into stunning pieces like diamond earrings, necklaces, and even tennis bracelets.
What Makes the Oval Diamond So Beloved?
The Illusion of a Larger Size
One of the main reasons behind the rise of the oval cut diamond's popularity is because they appear larger than their actual carat weight. An elongated shape causes the eye to follow down its length, which creates a feeling of size. For example, a 2 carat oval diamond engagement ring will generally appear larger than a round diamond of the same carat weight - making it a great option for people who want the biggest looking diamond without paying an exponential price for more carat weight!
Signature Brilliance and Fire
The oval diamond sparkles just like a round brilliant, as it is cut with the same facet pattern. The diamond offers scintillation, which is the effect of light playing upon the stone, producing brilliance (white light return) and fire (rainbow flash). The oval cut radiates this signature sparkle whether it is an oval diamond engagement ring or an oval diamond eternal band, and if that isn't enough to catch everyone's attention from multiple angles, we don’t know what will!
Exceptionally Flattering on the Finger
The elongated shape of an oval diamond has an immediate slimming and lengthening effect on the finger, making it a complimentary look for all hand sizes and shapes. Whether you opt for a simple 14K yellow gold solitaire engagement ring or a more intricate platinum halo ring setting, the diamond's proportions offer a refined, elegant feel that is also trendy.
A Perfect Blend of Classic and Modern
The oval is a unique, softer take on the classic round cut that creates a link between vintage and contemporary. This mix of elegance with trendiness has made it a favorite among celebrities, with recent high-profile proposals like Cristiano Ronaldo’s highlighting its status as a symbol of modern romance. Ronaldo paired Rodríguez’s oval center stone with additional oval side stones, showcasing a beautiful three stone oval diamond engagement ring—a timeless symbol of a couple’s past, present, and future. The beauty of an oval diamond engagement ring is that although it looks timeless, the elongated shape feels fresh, which is why oval diamond engagement rings are a popular choice for couples who want a little bit of tradition but are also looking for a sense of individuality.
The Advantages of Choosing a Lab Grown Oval Diamond
Ethical and Sustainable
Choosing a oval lab grown diamond means embracing both beauty and responsibility. Lab created diamonds are grown in highly controlled environments that replicate the Earth’s natural processes, but without the environmental disruption or ethical concerns tied to traditional mining. For couples that want their oval diamond wedding ring to openly symbolize their love without compromise, lab created diamonds offer a sustainable and conflict-free alternative, making them the ideal choice for modern romance.
Exceptional Value and Quality
A lab created diamond has the same chemical, physical and optical attributes as mined stones but with a dramatically lower price point. This means you can often choose a larger carat size — such as a 3 carat oval diamond ring or even a 5 carat oval diamond ring — while staying within budget. With exceptional brilliance, durability, and certified grading reports from top institutions like GIA or IGI, lab grown oval diamonds provide outstanding quality and value. Its the best mix of luxury and practicality making them a smart investment for engagement rings, earrings, necklaces or an oval diamond tennis bracelet.
Designing Your Oval: Popular Settings and Styles
The Timeless Solitaire
When it comes to highlighting the natural beauty of an oval cut diamond, the solitaire engagement ring setting remains one of the most timeless and admired choices. A sleek band paired with a luminous oval diamond allows the stone’s brilliance to take center stage. Minimalist engagement rings have a unique beauty in showcasing the shape of the diamond - in this case, the elongated shape of the oval stone, creating both a refreshing look and a timeless setting.
Elegant Halos and Pavé Bands
For those who adore added sparkle, halos and pavé bands offer just the right amount of brilliance and dimension. A halo of smaller diamonds will provide extra fire to the centered oval stone, as well as provide added visual size. A 2 carat oval diamond ring with a halo of smaller diamonds will be visually similar to a 3 carat oval diamond ring. A thoughtful choice for couples who want added glamour and visual size without the higher carat price.
Vintage-Inspired Designs
An oval shaped diamond ring with vintage-inspired details brings a romantic, heirloom quality to a modern engagement. Subtle details such as filigree detailing, milgrain edges, or engraved bands accentuate the oval diamond’s graceful curves and add depth and dimension. This style is especially important to those who want their oval diamond wedding ring to feel special, vintage, heirloom-style, personal, and timeless.

Tips for Finding Your Perfect Oval Diamond
Understanding the "Bow-Tie Effect"
One of the most unique aspects of an oval cut diamond is the possibility of a “bow-tie effect”—a shadow that runs across the center of the stone. All ovals will have some degree of a bow tie effect. The focus is simply to find a diamond in which the bow tie effect is subtle and balanced so that brilliance and fire dominate. A well-cut oval will project an incredible amount of light, without any interference, so you can see a stunning diamond at all times from all viewing angles.
Finding the Right Length-to-Width Ratio
The oval diamond ratio, or length to width ratio of your oval diamond, determines how elongated or round the oval shape will appear. A standard oval diamond ratio should be between 1.35 and 1.50 for an elegantly and elongated shape that flatters the finger. If you desire a bold and more noticeable presence, there is an opportunity for a higher ratio to possess a more dramatic silhouette, which is key to elongated oval diamond rings with high ratios. Ultimately, it's about personal preference and which length-to-width ratio complements your hand best.
The Importance of a Certified Grading Report
When buying an oval shaped lab grown diamond, it is important to look for a certified grading report from a reputable laboratory such as IGI or GIA to confirm that your stone has been graded for the 4Cs - cut, color, clarity, and carat weight. With a certification you can have peace of mind to shop with confidence. This is especially important with larger stones; if you are looking for a 2 carat oval diamond ring or a 3 carat oval diamond ring quality differences can drastically affect not only the beauty of the stone, but also its value.
Your Oval Lab Grown Diamond Awaits
From the classic glamour of a solitaire oval diamond engagement ring to an oval diamond pendant necklace, the oval cut provides limitless ways to celebrate love and individual style. Its combination of sparkle, elegance, and contemporary style has made it a popular choice for engagement rings and fine jewelry. No matter what your style is, the ideal oval diamond awaits to be found.
