Size Guide — Bless Jewel Studio

Ring sizes

Every ring is listed in US sizes, cut to order from size 3 to 13 in half steps. Inside diameter and circumference are the two measurements that matter — match either one and the size follows.

How to measure

1 · With a paper strip

1. Cut a strip of paper about 6 mm wide.
2. Wrap it around the base of the finger, snug but not tight.
3. Mark where it overlaps, unwrap, and measure to the mark in mm.
4. That reading is your circumference — enter it opposite.

2 · From a ring you own

1. Pick a ring that fits the same finger.
2. Lay it flat and measure straight across the inside edge.
3. That reading is your inside diameter — switch the unit opposite.

Measure warm

Fingers shrink in the cold. Measure at the end of the day, at room temperature.

Mind the knuckle

If the knuckle is wider than the base, size to slip over it — then tell us and we will fit the band.

Wide bands sit tighter

Anything over 6 mm wide wears about a half size smaller. Go up a half.

Measure three times

Take the reading on three different days and use the largest.

Necklace lengths

Lengths are measured end to end including the clasp. Where a piece falls depends on your neck and frame, so treat these as a guide — every chain can be shortened or extended free of charge.

Length	Metric	Name	Where it sits
14"	35 cm	Collar	Snug at the base of the neck
16"	40 cm	Choker	At the hollow of the throat
18"	45 cm	Princess	On the collarbone — our most requested length
20"	50 cm	Matinee	Just below the collarbone
24"	60 cm	Matinee long	At the top of the bust
30"	75 cm	Opera	Below the bust — wears long or doubled
36"	90 cm	Rope	At the waist — designed to be layered or knotted

To measure your own: wrap a soft tape where you want the piece to fall and read it in inches. Layering two? Leave at least two inches between them so the pendants do not sit on one another.

Bracelet sizes

Measure around the wrist just below the wrist bone, then add about a centimetre of room — a bracelet should turn on the wrist, not grip it.

Size	Wrist measurement	Bracelet length
XS	14.0 – 15.0 cm	6.5"
S	15.0 – 16.0 cm	7.0"
M	16.0 – 17.0 cm	7.5"
L	17.0 – 18.0 cm	8.0"
XL	18.0 – 19.0 cm	8.5"

Tennis bracelets and rigid bangles have far less give than a chain — if your wrist falls between two sizes on those, take the larger.

Earring dimensions

Earrings need no sizing, but the measurements below decide how a pair wears. Every product page lists the exact figures for that piece.

Studs

Posts are 11 mm as standard with a friction back. Screw backs are available on request at no cost — tell us at checkout.

Hoops

Hoop sizes are quoted as outer diameter: 10–15 mm reads as a small everyday hoop, 20–30 mm as a statement, 40 mm and above as an evening piece.

Drops

Drop length is measured from the top of the post to the lowest point of the setting, and is listed on each product page.
