Jewelry is fairly simple to size, but we've put together this guide to help you find the best fit. This information may or may not be applicable to jewelry from other designers - we haven't re-invented the wheel as fas as sizing goes but we can't speak for how other jewelers do it either.
Of all jewelry categories, bracelets are probably the trickiest item to fit - and bangles and cuffs fit very differently. Bangles must pass over the knuckles with the thumb compressed tightly. When passing over the widest part of the hand, the bangle should feel very snug. This will ensure it won't slide off during wear.
Oval cuffs however, should fit as snugly as possible directly on the wrist. A small gap in the cuff allows the wrist to pass through, and a snug fit will ensure it stays on.
Just for reference, I have a relatively wide hand and a thin wrist, as shown in the drawing above. This means I wear a size medium bangle and a size small cuff. Knowing the general proportions of a person's hands can help you decide which size to choose as a gift.
Size falls within a range, and in this diagram the dashed lines represent those parameters. If it's helpful, you can click on the image above to download a to-scale reference. (If you print it, make sure "scale to fit" of "fit to page" is unchecked. It's already sized for 8.5" x 11" paper.)
Our statement necklaces are sized by neck measurement. This measurement should be taken at a different point on the neck for chokers and for collars. The diagram below shows what I mean.

While we strive to size everything according to any established industry standards, rings are probably the most consistently sized item in the jewelry industry. Our rings are available in standard US sizes 4 - 10.5.
I have tried several DIY ring sizing methods myself with inconsistent results, so I don't recommend relying on any string or paper wrapping method. What I do recommend is this inexpensive ring sizer. It's on Amazon, so if you have a Prime membership it should arrive super quickly. (Do note, they use dashes to represent half-sizes, so a ring sizer marked "7 -" means "7.5" not "7".)
We are not in any way affiliated with this product, but have one of these in our tool kit and have found it to be very accurate. We even advised a couple that we made wedding rings for to get this sizer. Their rings turned out great and were the right sizes for their big day!
If figuring out the right size still seems like too much trouble, there are always earrings and pendants, which are one size fits all.
I hope this info helps, but if you have any questions feel free to comment below or email me at Katherine@xover0.store.
