All our Jewelry is Handmade.
You will find many websites on the internet that sell jewelry. Most of the time, it is mass-produced, meaning that rings and solitaires are all identical. We propose custom-made jewelry because we know that every diamond is unique in shape and size. Your ring will be designed according to the dimensions of the selected diamond; this is how we bring out the brilliancy of the diamond set on your engagement ring. Thanks to their experience, our jewelers will know how to calibrate correctly the setting of your solitaire ring; a prong will not be the same size if we want to set a 0.30 carat diamond or a 1 carat diamond.
