Ruby became the traditional 40th anniversary stone through Victorian-era anniversary gift lists. Its red color symbolized deep love, and its hardness (9 on the Mohs scale) represented the strength of a 40-year marriage.
Prices vary based on ruby size, quality, and setting complexity. Our 40th anniversary necklaces include smaller ruby pendants and pieces with larger or rarer stones.
All rubies in our collection are natural gemstones, sourced from mines in Myanmar, Madagascar, and Mozambique. Each product listing specifies whether the stone has received any treatments.
