THINGS TO TAKE INTO CONSIDERATION WHEN CHECKING YOUR RING SIZE.
The thicker the ring, the tighter the fit, so if you choose a ring with a deep band width, you will likely need to go one size up. Likewise, if you're going for a set of stacking rings of three or more, go up half to a full size to take account of that.
The best time of day to measure is in the evening, when your fingers are largest. Avoid measuring when you’re cold, as fingers are at least half a size smaller.
HOW TO SECRETLY MEASURE FOR RING SIZE.
All of the above methods are easy enough to measure your own ring size but what if the ring is a gift and you want to keep it secret? Don't worry, there are some options.
The easiest one is to borrow a ring that fits the person in question really well. Ideally you should borrow the ring for long enough to take it to a jewellers to get it measured on a ring gauge. Remember that each finger is different so if you are planning on purchasing an engagement ring as a suprise, don't take the ring size of a ring which fits the person's thumb, or second finger. You'll need to use a ring which fits well on the ring finger.
If you can't borrow the ring for long enough to take to a jewellers shop - again, you could buy your own ring gauge (I think you can get them for less than £5 on ebay) or you could try the ring on your own finger, and make a mark where the ring sits. Then head to the jeweller and get the ring measurement that fits to that point on your finger.
Finally, and this one is probably a little obvious, but you could ask what ring size he/she is, either asking the person themselves, or phoning a friend or relative to see if they know.
WHY IT'S IMPORTANT TO GET THE RING SIZE RIGHT.
It's important to get the size as accurate as possible, as all of my rings are handmade to your exact specification. As a custom item I can't accept returns unless there is a fault with the ring.
If the ring is too small I can usually help, as I have a tool which enables me to stretch the band of rings a little - possibly up to 2 sizes depending on the ring. This would involve a small cost to cover my return p&p and time.
However, if the ring is too big I can't resize it. Reducing the size of the ring involves cutting through the band to remove some of the material, and then resoldering. Unfortunately, the temperature involved in the resoldering process is high, and flows round the band and into the stones causing heat damage; discolouration and cracking. I think some high street jewellers are able to reduce the ring size for you, as they have special tools to restrict the heat, but I'm not able to recommend anyone specifically.
You will notice that on my website the ring sizes are letters, and this is the UK ring size. If you have found your ring size in US sizing or European sizing which are both numerical just let me know as I can work with that.
I really hope that all helps, but if you have any problems or need some advice on sizing pop me an email, or leave a comment here.
