Whether you’re buying a gift or upgrading your personal collection, here’s everything you need to know before investing in princess cut diamond earrings (1 carat total weight).
📌 Why Choose Princess Cut Diamond Earrings?
The princess cut is the second most popular diamond shape after round. Known for its modern geometric lines and brilliant sparkle, it’s especially stunning in earrings due to its sharp angles and clean symmetry.
Key Benefits:
- Exceptional brilliance (second only to round brilliant)
- Contemporary style with timeless appeal
- Affordable per carat compared to round cut
- Perfect for everyday wear or formal events
When it comes to 1 carat princess cut diamond earrings, the total carat weight typically means 0.50 carats per earring—a sweet spot in size and price for many shoppers.
💡 What to Look for in 1 Carat Princess Cut Diamond Earrings
Before diving into retailers, let’s break down the essential features to consider when buying:
1. Diamond Quality (The 4 Cs)
- Carat: 1 total carat (0.50ct per earring) is noticeable but still subtle enough for daily wear.
- Cut: Prioritize Ideal or Excellent cut for maximum sparkle.
- Color: Look for G–H color for a near-colorless look that offers great value.
- Clarity: VS2 to SI1 clarity offers eye-clean stones without breaking the bank.
💎 Pro Tip: For earrings, you can go slightly lower in clarity than you would for a ring — they’re not examined as closely.
2. Certification
Always ensure your diamonds come with GIA or AGS certification. Both James Allen and Blue Nile offer certified stones with detailed grading reports.
3. Metal Type
Choose a metal that matches your skin tone and existing jewelry:
- White gold: Modern, clean look (most popular)
- Yellow gold: Warm and classic
- Platinum: Hypoallergenic, durable
- Rose gold: Romantic and trendy
4. Backings
For secure, everyday wear, screw-back or friction-back settings are ideal.
