Wedding Bands

Wedding band sizing differs from other ring sizing in one important way: the band will be worn for decades, through conditions that cause the finger to change size — temperature, physical activity, age. A wedding band sized exactly to the finger at room temperature may feel uncomfortably tight after a gym workout or in summer heat. The conventional wisdom is to size up 0.25 to 0.5 sizes from the precise measurement, which provides a comfortable fit across normal daily variation. For wide bands (8mm and above), sizing up another 0.25 size is also standard because wider bands sit tighter on the finger due to greater surface contact.

The scratch resistance of a gold wedding band is a function of its karat. 14K gold (58.5% pure) is significantly harder than 18K gold (75% pure) because the higher alloy content in 14K includes harder metals — copper and silver — that reinforce the gold's crystalline structure. Under daily contact with hard surfaces (keyboards, steering wheels, gym equipment), a 14K band will develop fewer visible scratches per year than an 18K band. Both bands will develop a patina over decades — a collection of micro-scratches that produces a matte or satin-like surface. This patina is considered desirable by many wearers; a jeweler can polish it back to mirror finish if preferred.

For matching wedding band sets (bands purchased together for two people), metal consistency is worth prioritizing. Two bands in the same karat (both 14K yellow gold, for instance) will age similarly and maintain the same color relationship over years of wear. Mixing karats — one 10K, one 14K — creates a slight color discrepancy that becomes more visible as the pieces age differently. Matching the karat, the construction standard (solid construction for both), and the finish (both polished or both brushed) creates a set that reads as intentionally paired regardless of style differences.
