At Gemini Diamond, we want your ring to fit perfectly. That’s why we offer one complimentary resizing within the first year of purchase.

What to Expect During Resizing
Our jewelers may add or remove small amounts of metal. Bands may become slightly thicker or thinner, though changes are usually subtle. Every resized ring passes strict quality checks.
Resizing Limitations
Some styles cannot be resized due to:
• Design complexity (e.g., eternity rings, >¾ diamond coverage)
• Size changes beyond recommended ranges (most up to ±1.5 sizes)
If resizing is not possible:
• Within 30 Days — Ring may be remanufactured free of charge
• After 30 Days (within 1-Year Policy) — A fee may apply
You will always receive a quote before any work is performed.
Trusted Gemologist Guidance
At Gemini Diamond, we believe choosing the perfect diamond should feel informed and confident. That’s why we offer every customer complimentary gemologist reports with a side-by-side analysis of up to three diamonds.
What You’ll Receive
• Certification & Grading (GIA, IGI, etc.)
• Face-up Measurements & Proportions (with guideline comparisons)
• Light Performance & Visual Impact
• Durability & Resizing Considerations
• Price Transparency with value notes
Example of Our Reports
• Diamond 1: IGI certified, excellent cut, lowest cost, smaller face-up area, strong presence.
• Diamond 2: GIA certified, largest face-up, strongest durability, slightly warmer tone.
• Diamond 3: GIA certified, HPHT grown, very high clarity, higher price.
