Sell Your Monnickendam at ALLU

Founded in 1890, Monnickendam is one of the world’s three most prestigious diamond cutter brands. Their excellent cutting techniques have earned them the esteemed Queen’s Award for British Industry, presented by Queen Elizabeth herself. Monnickendam truly grasps the essence of each rough diamond, then meticulously brings that essence to life through precise cuts and intricate craftsmanship. Monnickendam’s “Fancy Cut” techniques, seen in cuts such as Oval Shape, Pear Shape, Marquise, Heart Shape, and Emerald Cut, are widely recognised as the most beautiful in the world.

In 1920, second-generation president Albert Monnickendam changed the company name to “A. Monnickendam.” Their reputation continued to grow with their advanced polishing techniques and experienced crafters. In 1948, they were entrusted with cutting a rough diamond donated by the Tanganyika government into earrings as a wedding gift to Princess Elizabeth. Thanks to their stunning success, Monnickendam gained further renown as they continued to develop their exquisite craftsmanship.

As a result, in 1954, they successfully developed a new polishing technique known as the “Circle of Luster”. True to its name, the polished stone radiates and shines like a circle of light. Albert and his son Arthur continually strove for beautiful diamonds, and their joint collaboration was responsible for the steadily increasing demand for diamonds in various countries. Monnickendam meets customer requests with meticulous customisation and craftsmanship, resulting in highly satisfying pieces. Monnickendam’s jewels, with their precise techniques and brand value, fetch high selling prices.

About Icons

The manufacturing and distribution process for brand products emits large amounts of carbon dioxide (CO2) and consumes large amounts of water. The images below represent the amounts of carbon dioxide and water consumption that can be reduced by reusing a product.

Carbon Dioxide (CO2) Reduction

CO2 reduction expressed by the amount of CO2 absorbed by a cedar tree annually.

Water Consumption Reduction

Water consumption reduction expressed by the volume of the 200-litre bathtub.
(Typical household bathtub size)

About Our Calculation Method

Our Calculation Method

The 'Resale Impact' is not a display of an actual environmental reduction but rather a quantification of the environmental impact (CO2 emissions and water consumption) generated by the manufacturing and distribution process that can be theoretically omitted when a customer purchases a product we resell instead of a buying a brand new item of the same type. Since our calculation is predicated on the emissions in the omitted manufacturing and distribution process, actual reductions in environmental impact may differ from our projected estimate.
Since our company does not manufacture goods, our calculations cover any resold goods (watches, bags, jewellery (including bullion), apparel, and accessories).
Our company does not check and verify the actual numerical value of each item's environmental impact (CO2 emission and water consumption) for our Resale Impact. Instead, we base our calculations on data from the LCA database "Gabi*" and estimate the total environmental impact of an item's entire life cycle, from the procurement of its materials to its disposal and/or recycling. Our calculations were overseen by a third-party consulting firm.
Discrepancies in LCA results may occur due to differences in calculation assumptions or deficiencies in the manufacturing process.
Due to revisions in calculations, the latest calculated values of products may differ from those shown on product tags, etc.
