Upstairs jewelry, with a brand-new marketing model, drives jewelry stores into high-end office buildings (learning from the business strategy of Bird's Nest Village upstairs in Hong Kong), which not only saves the high rental cost of traditional jewelry stores, but also saves the high counter fees and shopping mall deduction points when entering the shopping mall. Through the innovation of sales channels, upstairs jewelry saves high expenses and directly returns the discount to consumers, subverting the iron law of traditional jewelry's high price and creating a price surprise that is 0%- 1% lower than the market price. At the same time, the upstairs jewelry successfully integrated the offline sales model and B2C e-commerce model, and introduced the concepts of various gems (gold, platinum, diamonds, emeralds, rubies, sapphires and emeralds) to the market for the first time, allowing consumers to fully experience the shopping pleasure and convenience of "free selection offline and easy purchase online".
