Ring size guide

Not sure of your ring size?

1. Measure a ring that already fits

Measure the inside diameter at the widest point in millimetres. An inside diameter of 17.0 mm corresponds to ring size 17.0.

2. Measure your finger

Use a narrow strip of paper, keep it snug but not tight, and measure the circumference in millimetres. Measure 2–3 times, preferably later in the day.

Size	Inside Ø	Finger circumference
15,0	15,0 mm	47,1 mm
15,5	15,5 mm	48,7 mm
16,0	16,0 mm	50,3 mm
16,5	16,5 mm	51,8 mm
17,0	17,0 mm	53,4 mm
17,5	17,5 mm	55,0 mm
18,0	18,0 mm	56,5 mm
18,5	18,5 mm	58,1 mm
19,0	19,0 mm	59,7 mm
19,5	19,5 mm	61,3 mm
20,0	20,0 mm	62,8 mm
20,5	20,5 mm	64,4 mm
21,0	21,0 mm	66,0 mm
21,5	21,5 mm	67,5 mm
22,0	22,0 mm	69,1 mm
22,5	22,5 mm	70,7 mm
23,0	23,0 mm	72,3 mm
23,5	23,5 mm	73,8 mm
24,0	24,0 mm	75,4 mm

Between two sizes? Ring width and your knuckle also affect fit. Ask us before ordering if you are unsure.

What if the size is not quite right?

For a ring purchased from us, you get the first ring size adjustment at a reduced price compared with our standard price, if the ring can be resized.

Finger size naturally varies.

Your finger can be a different size in the morning and evening, as well as in warm and cold weather. A ring does not need to feel exactly the same every day. A size adjustment is worth considering only if the ring is repeatedly too tight or too loose at different times.

Festive Janette Laboratory Diamond Ring 0.40 ct Rose Gold

Festive Janette Laboratory Diamond Ring 0.40 ... €1.890,00

Festive Janette Lab-Grown Diamond Ring 0.40 ct White Gold

An elegant and striking white gold Janette halo ring with lab-grown diamonds from Festive. Janette is a stylish halo ring, featuring a dazzling 0.18 ct brilliant-cut lab-grown diamond at its center. The center stone is surrounded by 12 smaller, yet beautifully sparkling, lab-grown diamonds, and the delicate band of the ring is adorned with lovely side stones. The ring is crafted from high-quality 14-carat white gold. The slender and straight flat profile band of the ring has a width of 1.9 mm. The Janette lab-grown diamond ring is suitable for wearing alone or paired with another ring; a line diamond ring pairs particularly well with this halo ring. The ring is also available in yellow and rose gold, as well as with natural diamonds.

Lab-grown diamonds, also known as synthetic diamonds (man-made diamond, lab-grown diamond), are diamonds whose formation conditions are artificially created in a laboratory. Lab-grown diamonds and natural diamonds share the same chemical, physical, and optical properties. However, while it takes millions of years for a natural diamond to form, a synthetic diamond takes only a few weeks to produce.

Festive diamond jewelry is born from Finnish goldsmith expertise, with Festive's roots extending all the way back to the 1940s. The manufacturer of Festive diamond jewelry, Kultasepät Narsakka Oy, is a Finnish family business that is now in its fourth generation. All Festive products are handcrafted in Hämeenlinna, Finland, and the products have been awarded the "Avainlippu" (Key Flag) and "Design from Finland" symbols. Festive is known for its Routa and Rakka ring models, among others; the Routa ring won the "Most Beautiful Ring of the Year 2020" competition.
