For Christmas, La Belgique Gourmande is turning its ballotins into a ticket to a diamond. With its One Box, One Diamond contest, the Brussels chocolate house has 3 one-carat natural diamonds up for grabs from 1 November 2026 to 3 January 2027.
💎 How it works, in three steps
- Buy a 500 g ballotin (450 g net weight): Assortment, All Dark or All Milk, in one of the 9 participating shops.
- Scan the QR code printed on your receipt.
- Fill in the online form with the receipt number and date of purchase, then answer a knowledge question and a tie-breaker question.
The rule fits on one line: 1 ballotin = 1 entry. Several ballotins on the same receipt? Fill in one form per ballotin, entering the same receipt number each time.
🍫 No diamond hidden among the pralines
The slogan says a ballotin “may hide a diamond”, but the official FAQ is clear: there is nothing to hunt for among the pralines. The ballotin gives you one entry, and there is no draw. Winners are selected from the correct answers to the knowledge question; in the event of a tie, the tie-breaker question decides, by the smallest gap with the exact figure.
💍 Three real, certified diamonds
According to the organiser, the prizes are three one-carat natural diamonds, each certified by the International Gemological Institute (IGI); the three certificates can be viewed on the contest website. The rules state that the prizes cannot be exchanged, transferred, refunded or converted into cash.
📅 Key dates
- Purchases: from 1 November 2026 to 3 January 2027 inclusive.
- Form: until 4 January 2027.
- Results: from 11 January 2027, by email or telephone, then on the brand’s social media. The winner is contacted within 30 days of the announcement and then has 15 days to come forward.

✅ Good to know
- The contest is open to any adult, whatever their country: if you win, the diamond can be sent to the address of your choice.
- You can give the ballotin as a gift and keep the receipt: that is what lets you enter.
- Receipt without a QR code, or a QR code that does not work: write to contact@labelgiquegourmande.com with a photo of the receipt.
- Submitting more forms than ballotins bought, or using a false receipt, cancels all of the participant’s entries and leads to exclusion.
- The contest website does not give the price of the ballotins.
- The rules are published in several languages; in case of discrepancy, the French version prevails.
The contest is organised by Belgique GOURMANDE SPRL, Galerie de la Reine 17 in Brussels. To discover another side of the house, read our report on La Tabletterie, the workshop where you create your own chocolate.
