By 1400, Thai lapidaries had developed advanced techniques in ruby cutting and heat treatment, establishing Thailand as a center for gemstone craftsmanship. This expertise not only enhanced the quality of rubies but also contributed to the country's economic growth through the gem trade. The skills developed during this period laid the foundation for Thailand's reputation in the global gemstone market.

Ruby cutting in Thailand during the 1400s influenced Southeast Asian literary traditions, with poetry reflecting on the power of gems and kingship. Poets like Sunthorn Phu celebrated the beauty and significance of rubies in their cultural narratives, intertwining themes of love, wealth, and heritage.
