For the more secretive amongst you

Whether it’s for that once-in-a-lifetime occasion or a surprise gift, sometimes things need to be kept under wraps.

1.

Raid their treasure box

Look through their jewellery for a ring they already wear. You can then pop into a boutique with it, and we’ll be able to take the measurement for you. Just make sure you put it back before they notice. We won’t tell, promise.

2.

Make your mark

If you think they might notice if one of their rings goes missing, place it on your finger and make a mark where the ring goes up to. If you then come into a Loupe boutique, we’ll be able to use this as a guide for their ring size.

3.

Conspiracy is key

If in doubt, call on a friend to help you find your beloved’s ring size. Whether they try on an existing ring or get them to try on their new engagement ring, well, that’s up to them. But asking their best friend is a surefire way to get all the details you need.

Loupe Insiders: Tips & tricks

We quizzed our Loupe diamond connoisseur, Chloe Adlestone, to find out some insider secrets (shhh).

Measure your hands when they're warm, as they tend to shrink when cold. At night, your fingers are at the largest, so that's the time to accurately get your perfect fit. Then, we’d recommend measuring your finger three times to allow room for error. Third time's the charm! And keep in mind that wider bands fit more snugly than narrow bands, so we recommend sizing up for comfort. But if you're still unsure and are between sizes, choose the larger one - it'll be easier to adjust.

Not for you? Not to worry

Once you’ve bought your Loupe ring, if it doesn’t give you the heart pumps or give them the goosebumps, fear not, we can give you a full refund or an exchange, as long as it’s still in its original packaging and accompanied by the receipt or proof of purchase.

Please note: There are some types of rings that we are unable to re-size so with this in mind, please ensure your ring is unworn if you require a different size as we may need to exchange it. For more information, please take a look at our returns policy.
