We take the confusion out of buying diamonds with our fair, transparent approach and exceptional service. This guide will walk you through everything you need to know to make an informed decision about your diamond purchase.
Your 6-Step Diamond Buying Journey
1. Set Your Budget
Establishing a comfortable budget is the first step in your diamond journey. Here's how to approach it:
- ✓ Browse our loose diamonds to understand current market prices
- ✓ Decide which characteristics matter most (size, quality, or setting)
- ✓ Small adjustments in color/clarity can save money without visible difference
💡 Pro Tip: Use our Diamond Price Calculator to understand how different factors affect pricing.
2. Understand Certification
Certification is your assurance of quality and value. We exclusively offer GIA-certified diamonds because:
GIA (Gemological Institute of America) is the most respected grading authority
Provides documentation for insurance and future valuations
Enables accurate price comparisons between diamonds
Guarantees the diamond is natural and untreated
3. Choose Your Shape
The shape of your diamond is a personal expression of style. Popular options include:
- Round
- Emerald
- Oval
- Radiant
- Cushion
- Pear
- Princess
Style Tip:
Choose a shape that reflects your personality or your partner's style. Round diamonds offer classic brilliance, while fancy shapes make a unique statement.
4. Match the 4 C's
The 4 C's (Cut, Color, Clarity, and Carat) work together to determine a diamond's beauty and value.
Cut ✄ The most important C - affects sparkle and brilliance. Ideal cuts reflect maximum light.
Color 🎨 Graded D (colorless) to Z (light color). Near-colorless (G-J) offers great value).
Clarity 🔍 Measures internal inclusions. VS2/SI1 clarity often appears "eye-clean" at lower cost.
Carat ⚖️ Diamond weight. Consider spread (face-up size) which varies by cut quality.
5. Online vs. In-Store
Choosing between online and in-store purchases depends on your priorities. Consider these factors:
Online Shopping
