Measure an existing ring

To find your size, measure the internal diameter (in millimeters) of a ring that already fits you well. Place the ring on a ruler/caliper and measure the inside from edge to edge. Compare with the table:

BR Size	Internal Diameter (mm)
10	15.0
11	15.1
12	15.2
13	16.0
14	16.1
15	17.0

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.

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

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

Lab-Grown Diamond

It's a real diamond! (same physical and chemical composition)
Visually identical to natural, with a better size/price ratio.
Produced in a controlled environment; Gemological certificate for gems over 1 ct (upon request).

Natural Diamond

Rarity and tradition: formed in nature over millions of years.
Maximum hardness (10 Mohs) and classic diamond brilliance.
Available with gemological certification for gems over 0.30ct (upon request)
