The price for DIY engagement ring workshop is determined by the size of diamond (carat), width, and add-ons.
You may choose the size of the diamond after taking a closer look at our atelier.

A 0.1-carat diamond is an affordable option that makes a beautiful, simple, and subtle ring. Despite being on the petite end, its color, clarity, and cut are selected carefully to meet the standards of other diamonds we offer.
Diameter 3.8mm
A 0.2-carat diamond sufficiently brings out the brilliance of the ring. It acts as an accent to special occasions such as dinners, parties and holidays, and is befitting for everyday wear.
Diameter 4.3mm
A 0.3-carat diamond, slightly larger and with a broader head, leaves an augmented impression on the finger.
