Choosing the perfect pair of sunglasses isn’t just about trend or taste—it’s about balance, proportion, and harmony with your facial structure. If you have a diamond-shaped face, you’re in luck. This elegant and rare face shape offers versatility and definition that pairs beautifully with a variety of frame styles. But with so many choices out there, which sunglasses truly flatter a diamond face shape?
At ROYALTAIL, we specialize in precision-designed sunglasses that not only elevate your fashion game but also enhance your natural facial features. This detailed guide explores the best sunglasses styles that complement diamond-shaped faces, helping you find your perfect fit.
Understanding the Diamond Face Shape
Before selecting sunglasses, it’s important to understand the key characteristics of a diamond face:
🧊 Defining Features:
-
Narrow forehead and jawline
-
High, defined cheekbones (widest part of the face)
-
Tapered chin
-
Angular overall appearance
The diamond face is balanced yet edgy, with striking bone structure. The goal when choosing sunglasses is to soften the angles slightly, bring balance to your features, and avoid overly narrow or sharp-edged frames that emphasize width too strongly.
The Right Sunglasses Can Make All the Difference
With diamond-shaped faces, the key is to:
✅ Soften the cheekbone width
✅ Draw attention to the eyes
✅ Add width to the narrow forehead and jawline
✅ Maintain balance and elegance
Let’s explore the best ROYALTAIL sunglasses styles for this unique face shape.
1. ROYALTAIL Horizon Cat-Eye – The Feminine Favorite
The cat-eye silhouette is a flattering match for diamond faces. Its sweeping upper corners draw the eye upward, helping balance a narrow forehead while complementing angular cheekbones.
🌟 Why it works:
-
Softens your lower face and adds lift
-
Curved edges contrast nicely with sharp features
-
Adds width to the upper half of the face
🔍 ROYALTAIL Pick:
Horizon Cat-Eye – Featuring gold metal frames with pink or gradient brown lenses, this model is ideal for fashion-forward women who want timeless elegance.
Best For: Brunches, holidays, and vintage-inspired outfits.
2. ROYALTAIL LuxeRound – Classic with a Soft Touch
Round sunglasses are a go-to for angular face shapes, making them ideal for diamond faces. They add a sense of softness and contrast that smooths out harsh lines.
🌟 Why it works:
-
Balances the cheekbones
-
Softens the chin and jawline
-
Adds width in just the right places
🔍 ROYALTAIL Pick:

3. ROYALTAIL Glide Oval – The Understated Hero
Oval sunglasses combine the benefits of both square and round frames. Their slightly elongated shape harmonizes with the vertical length of a diamond face, without adding too much width to the cheekbones.
🌟 Why it works:
-
Compliments the natural symmetry
-
Softens angularity while maintaining edge
-
Works for both men and women
🔍 ROYALTAIL Pick:
Glide Oval – Lightweight acetate frame with polarized UV400 lenses. Available in black, caramel tortoise, and smoked grey.
Best For: Business casual looks, daily commutes, and understated style.
4. ROYALTAIL Skyline Aviator – Timeless & Gender-Neutral
While aviators are generally known for suiting oval and heart-shaped faces, slightly modified aviator frames with thinner, sleeker profiles can also suit diamond faces well—especially for men.
🌟 Why it works:
-
Balances cheekbones
-
Adds softness to angular structure
-
Ideal when fitted correctly
🔍 ROYALTAIL Pick:
Skyline Aviator – Thin metal frames with double bridge, matte or mirrored lenses, and custom-fit temple arms.
Best For: Men with sharp features, professionals, and anyone who loves a timeless classic.
5. ROYALTAIL BrowLine Fusion – Bold and Structured
Browline sunglasses feature a strong upper frame that mimics the natural line of the eyebrows. This design draws attention upward, which is perfect for balancing a narrow forehead and chin.
🌟 Why it works:
-
Highlights your eyes
-
Adds balance and width to the top of your face
-
Complements high cheekbones
🔍 ROYALTAIL Pick:
BrowLine Fusion – A hybrid acetate-metal frame with vintage detailing. Available in bronze, black/gold, and translucent espresso.
Best For: Retro lovers, fashion stylists, and confident trendsetters.
Sunglasses Styles to Avoid for Diamond Faces
While diamond faces are versatile, there are some styles that may overpower or underwhelm your features:
🚫 Tiny/narrow frames – Can make your cheekbones look too wide in contrast
🚫 Very angular geometric frames – Overemphasize the already sharp lines
🚫 Overly decorative temple arms – Distract from your natural symmetry
Instead, opt for balanced, softly curved, and flattering silhouettes like those from the ROYALTAIL lineup.
How to Pick the Perfect Frame for You
✅ Frame Width Matters
Choose frames that are slightly wider than your cheekbones but not excessively large. This ensures a balanced, structured look.
✅ Color Counts
-
Warm skin tones: Go for gold, tortoise, or brown
-
Cool skin tones: Choose black, silver, or grey
-
Bold personalities: Try gradient lenses or tinted glass in blues, pinks, or greens
✅ Lens Shape
For diamond faces, opt for:
-
Soft curves (round or oval)
-
Subtle upswept corners (cat-eye)
-
Thin rims or semi-rimless options
