I’m so happy with my purchase. It looks even better than the image online. It was a gamble to purchase something without seeing it firsthand but I so pleased that it did! The quality is impeccable and service was brilliant. I would definitely recommend Tertius Collection for anyone seeking to buy luxury accessories for their home.

I have ordered a beautiful wine cooler as a surprise for my partner and Tertius went above and beyond to make sure it was delivered according to my request. Thank you!

Tertius himself and his boutique are absolutely lovely! The man himself is a very open and creative person that likes to share his positive vibe and ideas with others. His collection is truly mesmerizing with different inspirations and stories which makes it very hard to look away! A lot of love and passion has been put into his work which reflects both on how Tertius carries himself and how his collection speaks without words. A visit worth a hundred times! A place of awe that fits perfectly between the busy streets of Amsterdam.

The seller was a really nice guy, he gave me some good advice about the product “a watch”. And even some discount.
Thanks you again and we will meet soon for a another piece of art.

Lovely vase and perfect service. I couldn’t find the vase I was looking for online but within minutes the owner had sent me pictures of the vases and I quickly found the one I needed. It was wrapped and packed perfectly also. Thank you :)
