Guide to Grau Ringss

At Grau, we use the Spanish and European measurement table.

If you don't know your ring size, we suggest different ways to find it out:

Method 1 - Measure a ring

Measure the diameter of a ring you already have and find the equivalence.

1. Choose a ring that you already have and that fits you well.

2. Using a tape measure or ruler, measure the inside diameter.

3. Write down the result and find out what your height is according to the equivalence table below:

DiameterSpanish SizeEuropean Size

15,2 mm848
15,5 mm949
15,9 mm1050
16,2 mm1151

16,8 mm1353

Method 2 - Measure your finger

Measure the circumference of your finger with a strip of paper and look in the table of equivalences.

1. Cut a small strip of paper about 1 cm wide.

2. Wrap the finger with the paper, without pressing too much and gently.

3. The bottom end will be the starting point.

4. On the remaining piece of paper, mark with a pencil or pen the final reference point (as shown in the video).

5. Unfold the paper and measure the result with a measuring tape or ruler. This is the outline of your finger.

6. Write down the result and check what your size is in the equivalence guide:

Pomellato rings

Pomellato rings follow the French / European sizing standard.

From the firm they indicate that the adjustment of a ring varies according to its design. It happens more or less the same as with clothing and footwear.

By fit we mean the adaptability and adjustment of the ring to the finger and regardless of its size, it can be defined as follows:

  • Standard: Close to the actual measurements of the finger. The size matches the measurements.
  • Narrow: Tends to be difficult to remove. It may be necessary to increase its size.
  • Loose: There is space between the finger and the ring, and it may be too loose. It may be necessary to reduce its size.

To find the ideal Pomellato size, the Italian firm offers you two printable documents with two different methods:

Measurement with a ring.

Finger measurement.

Similarly, below you will find a table of equivalences that may be useful:

Uno de 50 Necklaces

The measurement of a necklace is calculated based on its length, that is, what it measures from one end to the other, extended.

Many necklaces are adjustable, so you can adjust the size to your liking taking into account the minimum and maximum length.

If the necklace has a bead, its size is not included in the minimum and maximum size.

To find the ideal size for your necklace you can do it as follows:

1. Measure a necklace you have, from one end of the clasp to the other, on a flat surface.

2. Place a tape measure around your neck, adjust it, and record the measurement.
