British jeweler Beaverbrooks, which is celebrating its 100th anniversary this year, is getting a head start on the holiday season with its “diamond a day” advent calendar. According to IDEX Online, the £100,000 ($125,000) calendar is essentially a 25-drawer piece filled with diamond rings, necklaces, bracelets, watches and earrings, which the owner can open in the countdown to Christmas.

Inside the calendar are several noteworthy pieces, including a Once platinum diamond solitaire ring worth £26,000 ($32,400), a £4,250 ($5,300) Beyond Brilliance 18-carat white and rose gold diamond earrings featuring Beaverbrooks’ 100 facet diamonds, and a £975 ($1,200) 9-karat white gold diamond pendant from the True Connections collection.

The 25-day diamond countdown piece is offered for $125,000 – saving the lucky owner £23,000 ($28,600) over buying the pieces individually. According to Beaverbooks, this is the first calendar of its kind, and only a limited number of calendars is available.
