Dune Lab Grown Diamond Engagement Ring 1 ct in 18K Gold

Sale priceR$ 9.990,00

Dune is crafted from 18K gold and features a 1 ct lab-grown diamond in a bezel setting.

Tip: Measure at the end of the day and avoid measuring with cold fingers. If you're between two sizes, the larger one is usually more comfortable. If in doubt, contact us.

Measure your finger (paper strip or string)

If you don't have a ring as a reference, use a paper strip (or string) to measure the circumference of your finger and convert it to your ring size.

  1. Cut a thin strip of paper (±5 mm wide) or use a thin string.
  2. Wrap it around the finger where the ring will be worn. (Don't overtighten; simulate real comfort.)
  3. Mark the meeting point with a pen.
  4. Lay the strip flat and measure the distance between the marks in centimeters (cm).
  5. Use your measurement in centimeters to find the corresponding size in the table below.

Reference table – finger circumference (cm) × BR size:

BR Size Finger Circumference (cm)
10 4.8
11 4.9
12 5.0
13 5.1
14 5.2
15 5.3
16 5.4
17 5.5
18 5.6
19 5.7
20 5.8
21 5.9
22 6.0
23 6.1
24 6.2
25 6.3
26 6.4
27 6.5
28 6.6
29 6.7
30 6.8
31 6.9
32 7.0

Important: Ensure the measurement passes over the knuckles (the widest part of your finger). If you are between two sizes, please contact us to confirm — the 1st adjustment is free.
