The price for DIY engagement ring workshop is determined by the size of diamond (carat) and the addition of secret stone on the ring. The choice of metal (e.g. platinum and 18k gold) poses no influence on the final cost. You may choose the size of the diamond after taking a closer look at our atelier.


0.2 carat (3.8mm± in diameter)

0.3 carat (4.3mm± in diameter)


A 0.3-carat diamond, slightly larger and with a broader head, leaves an augmented impression on the finger.


0.5 carat (5.0mm± in diameter)


A 0.5-carat diamond for an engagement ring is a luxurious choice. This diamond size is a showstopper that fills one with envy.
