The unit used to express the weight of a diamond is the carat.
We offer a variety of sizes to suit your design and preferences at Quarantotto.
Many customers choose 0.2 to 0.3 carats.

Clarity refers to the amount of inclusions, or internal imperfections, that naturally exist within a diamond.
At Quarantot

They almost always have distinctive color characteristics.

The cut is arguably the most important factor in determining the brilliance of a diamond.
The balance of the cut, symmetry, and polishing are all factors that earn an "Excellent" rating.

The fit and comfort of a ring can vary depending on its design, so we recommend having your finger measured at a nearby store.

If it is difficult for you to visit our store, we offer a free ring sizer rental service via the link below, so please feel free to use it.

If you are taking the measurements yourself, please refer to the following.

[How to measure]

- Wrap a string or thread around the thickest part of the finger where you want to wear the ring, and place it where the two overlapping strands meet.
Draw a line with a pen.
By measuring the distance between those lines, you can measure the circumference of your finger (inner circumference).
Please check the size chart to find the correct size.

Please measure the inner diameter of your ring and check the size chart to determine the correct size.

Due to limited quantities, the color may change.
