There’s something unmistakably elegant about a square cut diamond ring. Its clean lines, geometric symmetry, and captivating sparkle have made it one of the most sought-after diamond shapes for modern engagement rings and luxury jewelry pieces. At Vermont Gem Lab, we’ve seen the square cut become a favorite among couples who desire a look that’s both classic and contemporary.
From custom engagement designs to bold anniversary gifts, square cut diamonds are an exceptional choice for anyone looking to celebrate love, achievement, or personal style. In this post, we’ll explore everything you need to know about square cut diamond rings—what they are, why they’re so loved, and how you can design the perfect one with Vermont Gem Lab.
What Is a Square Cut Diamond?
A square cut diamond is defined by its geometric shape—equal sides and crisp corners—but within this family, there are a few stunning variations. The most popular include:
1. Princess Cut
Arguably the most popular square shape, the princess cut is known for its sharp corners and brilliant faceting that maximizes sparkle.
2. Asscher Cut
A vintage-inspired square cut with cropped corners and a distinctive step-cut facet structure. It offers a sophisticated, mirror-like reflection.
3. Cushion Cut (Square Variant)
With slightly rounded corners and soft edges, the cushion cut offers a romantic blend of old-world charm and modern brilliance in a square silhouette.
At Vermont Gem Lab, we help you choose the perfect square cut diamond based on your style preferences, budget, and the type of brilliance you desire.

Square Cut vs. Other Shapes: What Sets It Apart?
While round diamonds remain the most popular shape, square cut diamonds offer several distinct advantages:
| Feature | Square Cut Diamond | Round Brilliant Diamond |
|---|---|---|
| Look | Modern, architectural | Classic, timeless |
| Sparkle | Intense fire (princess), clean reflections (Asscher) | Balanced brilliance |
| Cost Efficiency | Less rough waste = better value per carat | Higher per-carat price |
| Design Flexibility | Great for halos, solitaires, and modern styles | Best in traditional designs |
Many clients who want something less conventional yet equally elegant find themselves drawn to the square cut diamond ring.
How to Choose the Right Square Cut Diamond
Here’s what to keep in mind when shopping for a square cut diamond ring:
1. Cut Quality
A well-cut square diamond maximizes light return. For princess and cushion cuts, symmetry and proportions are essential. For Asscher cuts, step facets must align perfectly to create the hall-of-mirrors effect.
2. Color
Square cuts show color more readily than round cuts, so consider diamonds in the G-H color range or higher for a bright white look.
3. Clarity
Inclusions may be more visible in step cuts like the Asscher, so look for higher clarity grades (VS2 or better) if clarity is important to you.
4. Carat Size
Square cuts appear slightly smaller than rounds of the same carat weight due to their cut depth. If visual size is important, opt for slightly larger carat weights or halo settings for added presence.
We’ll help you navigate all of these details at Vermont Gem Lab, ensuring you get the best stone for your budget and style.
Caring for Your Square Cut Diamond Ring
To keep your ring as beautiful as the day you received it:
- Clean regularly using warm water, a soft brush, and gentle soap.
- Avoid chemicals like bleach and chlorine, which can damage metal settings.
- Remove when needed during heavy lifting, sports, or gardening to protect your diamond and band.
- Store with care in a soft pouch or box to avoid scratches.
- Inspect annually by bringing it to Vermont Gem Lab for a professional cleaning and security check.
