Covert Ways To Estimate Her Ring Size

We understand that purchasing a diamond is a significant investment. That is why each Clean Origin Lab Created Diamond is independently verified and graded using the same scientific rigor applied to mined diamonds.

Method 1: Measure A Ring She Wears Now

Secretly “borrow” and measure a ring that fits her left-hand ring finger (or the finger you intend her to use). Tread carefully. You don’t want her to find out! Depending on how much time you’ll have with the ring before she notices it’s gone, here are a few tactics to consider:

1. Take it to a jeweler. If you have a few hours, take the ring to a local jeweler to size it professionally. While this takes more time, it’s also more accurate.
2. Invest in a ring mandrel like this one to quickly and accurately measure the ring yourself. Slide the ring down the mandrel. The line where the ring stops indicate the ring size.
3. Use the ring sizing chart. Be sure to print it ahead of time and use a ruler to double-check it’s precisely to scale. Move the ring from circle to circle until you find the best match for the ring’s inner diameter. If the ring lands between two sizes, always choose the larger one.
4. Trace it. Carefully trace the inside and outside of the ring on a piece of paper. Repeat several times for added accuracy. Take the paper to a jeweler for a size estimate.
5. Try it on yourself. If pressed for time, try the ring on your own fingers and see if one of them fits well. If it does, you can measure that finger later, on your own time.

Method 2: Pretend To Shop For Someone Else

If you’re up for the acting challenge, pretend that you want to buy a ring for someone else and ask her for help. Whether it’s your sister, grandmother, aunt, or mom, pick someone whose hands closely match hers. This could also be a great way to gauge her style, especially if you ask her for advice on color and other design elements. Here are a few tactics you can apply:

1. Casually ask her if she knows her own ring size. As you browse for rings, say your version of “I don’t know what ring size my mom wears. Do you know yours? I could use you as a reference.” Make sure this feels like a natural part of the conversation.
2. Ask her to try on rings. Pay attention to which size fits her best. If needed, take a solo trip to the store ahead of time to familiarize yourself with where and how sizes are listed.
3. Bring her a ring for approval. If visiting a store together is not possible, try purchasing an inexpensive ring you think would fit her. Casually ask her to try it on to make sure it “looks good” before you gift it to your mom. Pay close attention to the fit.

Method 3: Ask A Trusted Friend For Help

Enlist the help of a close friend or family member who may either already know her ring size or assist you in executing the other methods. Just make sure this is someone you can trust with your secret, otherwise, it’s not worth the risk. Here are a few questions to ask:

1. Do they already know her ring size? Perhaps her mom or best friend recently purchased a ring for her as a gift. In this case, they may already know her size.
2. Are they open to having her try on their rings? If they have similar sized hands, they could try each others’ rings for fun and in the process gauge her size.
3. Would they go jewelry shopping together? Whether at an artisan market, the mall, or even a jewelry store, they could browse for rings while also noting her size.
4. Can they ask her for her ring size? If the question fits naturally into a conversation, they can simply ask for her ring size without giving away your secret.

4. Insert the pointy tip of the paper through the slit.
5. Place the paper around her finger and gently tug until you have a secure, comfortable fit.
6. The number line that meets the slit indicates the ring size.

Final Considerations

Since some of these methods come with a margin of error, here are a few other considerations:

1. When torn between two sizes, always go with the larger one. It’s generally easier to size a ring down if needed.
2. Wider rings typically have a tighter fit and may require a slightly larger size to fit comfortably.
3. If possible, avoid measuring her ring size first thing in the morning or on extremely hot days, when fingers could be more swollen than usual.

Often confused with cut, the shape of a diamond is the physical appearance that it takes. The most popular shape is the round brilliant.
The cut of a diamond determines how effectively light that enters the stone is refracted within and reflected back through the top of the diamond, providing sparkle. The best cut grade is defined as Ideal, followed by Excellent, Very Good, Good, and Fair. Fancy shape stones often do not receive cut grades and will be listed as 'None.'
Carat refers to the actual weight of a diamond and is a unit of measure equal to 0.2 grams. In all diamonds, carat weight is a large contributor to the price of the stone.
The color in diamonds is actually the absence of color, graded on an alphabetical scale from D to Z, with D being a colorless diamond and Z being yellow.
Clarity measures the amount of inclusions or imperfections found in a diamond. The best clarity is VVS1 followed by VVS2, VS1, VS2, SI1, and SI2. Although other levels of clarity exist, we only carry diamonds with quality we can stand behind.
