Why Sapphire Engagement Rings?

Sapphire engagement rings have surged in popularity—and for good reason. They offer durability (9 on Mohs scale vs diamond's 10), unique colors, ethical sourcing, and 60-80% cost savings compared to diamonds.

But buying a sapphire engagement ring is more complex than buying a diamond. There's no universal grading system, treatment disclosure varies, and quality differences are massive.

This guide will save you thousands and ensure you get a ring your partner will love.

Understanding Sapphire Quality: The 4 Cs

1. Color (Most Important)

Color accounts for 50-70% of a sapphire's value. Look for:

• Saturation: Vivid, rich color vs washed-out or pale
• Tone: Medium to medium-dark (not too light or too dark)
• Hue: Pure blue, teal, parti-color, or pink (avoid muddy browns)

Best for engagement rings: Vivid blue, teal, or parti-colored sapphires with good saturation.

2. Clarity

Unlike diamonds, sapphires don't need to be flawless. Look for:

• Eye-clean: No visible inclusions to naked eye (most important)
• Minor silk acceptable: Fine needle-like inclusions that don't impact brilliance
• Avoid: Heavy inclusions, fractures, cloudiness

3. Cut

Cut affects brilliance and color display:

• Good proportions: Not too shallow or too deep
• Symmetry: Well-balanced facets
• No windowing: Avoid see-through areas in center

4. Carat Weight

Sapphires are denser than diamonds. A 1ct sapphire looks smaller than a 1ct diamond.

• Sweet spot: 1-2ct for engagement rings
• Price jumps: Significant increases at 1ct, 2ct, 3ct

Treatment Status: The $3,000 Difference

This is where most buyers get scammed. Heat treatment is permanent and acceptable—but it dramatically affects value.

Always ask: "Is this stone unheated and untreated?" Demand explicit documentation.
