How to Determine Your Ring Size

 

We are happy to assist you in determining the correct ring size. Figuring out your partner's ring size can be one of the most stressful aspects of purchasing an engagement ring, but there are lots of ways you can easily figure out the right size at home. The ring should fit your finger comfortably - snug enough so that it will not fall off, but loose enough to slide over your knuckle with some resistance. For example, the average ring size for women is between 5 and 7, but it’s always best to get an exact ring measurement before spending money.  

How to Measure Your Ring Size at Home

Two simple ways to choose the ring size correctly

1. Select an existing ring that fits the desired finger and measure the internal diameter of the ring (in mm). Then use the below chart to determine your ring size.


2. Wrap a strip of paper around your finger where you’d like your ring to be. Make sure that the paper is pulled snug to your finger, the tighter the better, to find your best fit. Mark the spot where the paper meets and measure the distance with a ruler (mm).

  • It's important! Your fingers tend to change size throughout the day — the best time to measure your finger is the end of the day.
  • If you are between sizes, order a larger size. Make sure your finger is at a normal body temperature -- fingers can shrink or expand when cold or hot. If your knuckle is much larger than your finger’s base, take two separate measurements and choose a size in between. You want a ring to fit over your knuckle, but not be too loose or it will shift around.

Q: Will this ring turn my finger green?
A: Absolutely not. We use strictly Solid 14k or 18k Gold, which is hypoallergenic, waterproof, and sweatproof. Unlike cheap plated jewelry or vermeil, our solid gold rings will never oxidize, tarnish, or discolor your skin.

A: Yes! Since we are Direct Manufacturers (not resellers), we can modify any design. We can swap the center stone for Moissanite, Lab-Grown Diamond, Sapphire. Just chat with us or leave a note at checkout!

Q: How do I know my size? (True to Size?)
A: Our rings fit True to US Sizing. If you are between sizes, we recommend sizing up for the most comfortable fit. We can also craft quarter sizes (e.g., 5.25 or 6.75) for a perfect fit—just specify this in the "Order Notes" in your cart.

Q: How long does production take?
A: Because this is Handcrafted to Order specifically for you (no old stock!), please allow 5-7 days for our jewelers to cast, set, and polish your ring before shipping.

A: We stand by our quality. Every ring comes with a Lifetime Warranty against manufacturing defects. If a stone feels loose or there is a structural issue, we will fix it.
