Emerald-cut lab-grown diamonds in a full circle, four prongs each, in solid 14K gold. The emerald cut is a step cut: long parallel facets that give broad flashes of light and show the clarity of the stone.

Set edge to edge around the band, the parallel facets line up into a continuous corridor of reflection. It is the most architectural of the eternity bands and the one that reads most clearly across a room.

Choose your total carat weight and metal, in quarter sizes from 3 to 15. A full eternity band is set to its final size when it is made, so measure properly first.

Every diamond is D–E color and VVS2–VS1 clarity, independently graded by IGI on the same 4C scale used for mined diamonds.

Every Rosette eternity band is made in quarter sizes from 3 to 15, so you can order the size you actually are rather than the nearest half. Use whichever method below you trust most, and if you are between two, order the larger one.

Find your ring size at home

1. Measure a ring you already wear

Take a ring that fits the finger you have in mind and measure the inside diameter across the widest point, in millimeters. Match that figure to the table below. This is the most reliable method because it measures the ring rather than the finger.

2. Measure the finger

Wrap a strip of paper or a length of string snugly around the base of the finger, mark where it overlaps, and lay it flat against a ruler. That measurement is the circumference. Match it to the table below.

3. Three things worth knowing before you order

Fingers swell in heat and late in the day, and shrink in the cold. Measure in the evening at normal room temperature.
Your knuckle has to clear the ring. If it is noticeably wider than the base of the finger, size to the knuckle.
Eternity bands sit differently to a plain band. Because the diamonds run all the way round, the band feels a fraction snugger, if your reading falls exactly between two quarter sizes, take the larger.

Quarter sizes. The table lists half sizes because that is what international scales convert to. Every quarter size in between is available on the product page. A quarter size is roughly 0.2 mm of diameter, or 0.65 mm of circumference. If your measurement sits between two rows, the quarter size between them is the one to choose.

Bracelet lengths

Measure around your wrist just below the wrist bone, then add roughly half an inch for a tennis bracelet, so it moves freely and stays on the wrist.

Wrist measurement	Order	Fit
5½″ – 6″	6½″	Close
6″ – 6½″	7″	Standard. The most ordered length
6½″ – 7″	7½″	Standard
7″ – 7½″	8″	Relaxed
7½″ – 8″	8½″	Relaxed

Necklace lengths

Length	Where it sits
14″	Choker, against the base of the neck
16″	At the collarbone. The most common tennis necklace length
18″	Just below the collarbone, in the hollow of the throat
20″	A few inches lower, above the neckline of most tops
22″	Mid-chest, layers well over a 16″
24″	Below the chest. Reads long and deliberate

Print a Rosette ring sizer

If you would rather measure with a physical gauge, print this page at 100% scale, no page scaling, no fit-to-page, and cut a strip of card 6 mm wide and 90 mm long. Mark it in millimeters, wrap it around the base of your finger, and read off the circumference where it overlaps. Check the print scale first against the bar below, printed at 100% it measures exactly 50 mm end to end. If it does not, your printer scaled the page and the sizer will read wrong.

0 mm to 50 mm, marked every 10 mm.

Printing is never perfectly reliable across different printers. If the piece is a gift, or you would rather not guess, email info@rosettejewelry.com with your measurement and we will confirm the size before anything is made.

If the size is wrong

Eternity bands are set with diamonds around the entire circumference, so they keep the size they are made in. Changing the circumference would change the number of stones. Half eternity bands and plain sections can usually be adjusted. If a piece arrives in the wrong size, contact us within the returns window and we will arrange an exchange for the correct one; see the returns policy for the terms that apply.

Still unsure? Get in touch. We would rather answer a question than have you order twice.

Metal: solid 14K gold, white or yellow. Gold all the way through, surface to core.
Stones: lab-grown diamonds, D–E colour and VVS2–VS1 clarity, independently graded by IGI on the same 4C scale used for mined diamonds.
Carat weight: figures given are total carat weight — the combined weight of every stone in the piece, or in the pair for earrings, not the weight of one stone.
Made to order: each piece is made for your order in our own Los Angeles workshop. Small variations in finish and stone placement are normal in handmade jewelry, and are what make each one particular to you.
Sizing: rings are made in quarter sizes from 3 to 15. See the size guide before ordering — full eternity bands cannot be resized afterwards.

Store each piece separately to avoid scratching. Remove jewelry before swimming, showering, or applying lotion and perfume. Clean gently with a soft cloth, and have prongs and settings checked periodically.
