The safest jewellery gifts when you do not know her size are the ones that have no size to get wrong: earrings and an adjustable necklace. Studs need no measurement and a pendant chain adjusts across a range. Rings and bracelets need a measurement. If you want to give one anyway, there are quiet ways to find the size first.
Start with what has no size
A gift that cannot be the wrong size is a gift you do not have to worry about. Two pieces in the Mariqe range fit that description.
The Eterna Necklace is a single round moissanite on a chain that the listing describes as 38 to 43 cm (15 to 17 inches) and adjustable. You do not need a neck measurement to choose it.
Stud earrings do not have a size in the ring sense. The post and back are standard, so the only choice is the stone. If you are unsure how large to go, our guide to what size stud earring suits a woman over 60 compares 6.5 mm, 8 mm and 9.1 mm stones against the face and earlobe.
One condition applies to earrings. They are for pierced ears, so check that she wears them. Pierced earrings also cannot be returned for hygiene reasons unless they arrive faulty, so a pair is a firm choice rather than a try-and-swap one.
Comparing the options
| Gift | Does it need her size? | From (checked 20 October 2026) | Can it be returned if wrong? |
|---|---|---|---|
| Eterna Stud Earrings | No, but she needs pierced ears | $78 a pair (0.5 carat in each earring, silver) | No, unless faulty |
| Eterna Necklace | No, chain is adjustable from 38 to 43 cm | $98 (1 carat, 6.5 mm) | Yes, 30 days from delivery |
| Petal Bracelet | Choose 16 to 18 cm or 18 to 20 cm, adjustable within each | $149 | Yes, 30 days from delivery |
| Eterna Ring | Yes, exact ring size | $79 (1 carat) | Yes, 30 days from delivery |
Prices are from the live product pages on 20 October 2026. Mariqe runs sales, so the page you see at checkout is final. Stud earring weights are per stone: a "1 carat x 2" pair carries 1 carat in each earring, so 2 carats in total.
If she wears a bracelet, the range helps
Bracelets are the middle case. The Petal Bracelet comes in two length bands, 16 to 18 cm (6 to 7 in) or 18 to 20 cm (7 to 8 in), and each is adjustable with a lobster clasp. That means you are choosing between two broad bands rather than guessing a single number.
To choose, look at what she already wears. A bracelet or watch that sits snugly points to the shorter band. One that slides along the forearm points to the longer one. If you cannot tell, ask a sister, a friend or her partner, who often knows without being asked directly.
If you want to give a ring
A ring is the most personal gift and the one where size matters most. Mariqe lists ring sizes in half steps, from 4 to 10.5 on the Eterna Ring, so you need an accurate size and not an estimate of small, medium or large.
These routes work without spoiling a surprise:
- Borrow a ring she already wears on the same finger and compare it against a ring sizer or a printed size chart.
- Ask someone close to her to do it. A friend can often try the ring on or measure one from her jewellery box.
- Check an old receipt or a past purchase if she has bought a ring online before.
- Remember that fingers can change with the weather, the time of day and over the years, so a size taken in cold morning air can read small.
If you still miss, the policy is workable. You have 30 days from delivery to request an exchange, and a flat $19 covers return shipping and restocking for a sizing change. Items must come back unworn in their original packaging. Our returns and exchanges guide sets out the full terms, including that faulty items are replaced free.
Order earlier than you think
Standard shipping is free worldwide. Mariqe processes orders within 48 hours and delivery is expected 7 to 10 working days after dispatch. Priority shipping is typically 5 to 7 working days, with the cost calculated at checkout. For a December gift, those numbers mean ordering in early November leaves room for a size exchange without a rush. We do not promise a delivery date, because carriers vary.
What arrives in the box
Each piece comes in a leather box with a velvet interior and a premium gift bag, along with a GRA certification record and a warranty card. The Lifetime Moissanite Warranty covers the stone itself. The GRA report is a record of the stone's details from the lab that issued it. It is not an independent valuation, and our guide to what a GRA certificate is and what it is worth explains the difference. Metal is 925 sterling silver with platinum or 18k gold plating.
What this means for you
If you do not know her size, choose the necklace, and choose earrings if you are sure her ears are pierced. Both are comfortable choices that need no measurement. If your heart is set on a ring or bracelet, gather one reliable clue first, order early, and keep the packaging until she has tried it on. A sizing change costs a flat $19 and the whole process is built to be forgiving.

What is the safest jewellery gift if I do not know her size?
An adjustable necklace or stud earrings. Neither needs a measurement. Earrings are only suitable if she has pierced ears, and they cannot be returned unless faulty.
Can I exchange a ring that turns out to be the wrong size?
Yes. You have 30 days from delivery to request a return or exchange. A flat $19 covers return shipping and restocking for a sizing change, and the ring must come back unworn in its original packaging.
How can I find her ring size without asking her?
Compare a ring she already wears on the same finger against a ring sizer or size chart, or ask someone close to her. Fingers vary with temperature and time of day, so confirm the size if you can.
Are Mariqe bracelets adjustable?
The Petal Bracelet is listed as adjustable within two length bands, 16 to 18 cm or 18 to 20 cm, and fastens with a lobster clasp.
How early should I order a gift?
Standard shipping is free and takes 7 to 10 working days after dispatch, and priority is typically 5 to 7. Ordering early in November leaves time for a sizing exchange before December.
