Ring Size Guide
Discover your ideal fit for Fiametta's rings, meticulously crafted with recycled gold and engineered for both exceptional quality and ethical purity. While it might seem that "trying until it fits" is the default approach to sizing the most popular jewelry piece in the industry, we're here to make the process as refined as our lab-grown diamonds.
The challenge becomes particularly real when selecting a ring as a gift, where standard S, M, and L sizes don't apply. Whether you're choosing an everyday statement piece, a milestone marker, or a gift for someone special, understanding ring sizing is essential for ensuring your piece fits perfectly.

Understanding Ring Sizes in the US
As a US-based brand, we use the American sizing system, which typically ranges from 3 to 13¼. Each number corresponds to the ring's inner diameter, measured precisely in both inches and millimeters.
For example:
- Size 6 = 0.67 inches (16.5mm)
- Size 7 = 0.69 inches (17.3mm)
- Size 8 = 0.71 inches (18.2mm)
While we primarily use US sizing, our comprehensive size chart includes international conversions, ensuring our pieces can be worn worldwide.
Quick Size Guide
Typical sizes:
- 4-5 (0.61-0.63 inches): Small
- 6-7 (0.65-0.67 inches): Most common for women
- 8-9 (0.69-0.70 inches): Large
- 10-11 (0.72-0.74 inches): Most common for men
