Onyx is the black version of the stone chalcedony. It is a hardness of 6.5 on the Mohs scale and is more prone to scratching than some other gemstones.

Clean onyx jewelry with Day's Jewelry Cleaner or mild dish soap in warm water: Use a toothbrush to clean behind the stone where dust, dirt and soap film may collect.

Ring Sizing:
At Day's Jewelers, standard size for lady's rings is 6-6.5, men's rings 10- 10.5. Our team of on-staff professional goldsmiths are prepared to custom size your ring very quickly, usually at no charge. Since it is best practice to size a ring only once, we recommend you order the ring in standard size. If it doesn't fit, the recipient should have his/her finger measured in a jewelry store and have it sized then.Your option to choose a size will appear when you hit the 'add to basket' button.

If this is not practical, there are a number of ways to determine finger size;

1) Take a ring you know is worn on the ring-finger (finger sizes can differ from right to left hand) to a jewelry store and ask them to tell you what size it is.
2) Take a slice of soft bread and press a ring that fits the ring-finger into the bread until a cut out or clear impression of the ring is left on the bread. Take this bread to a jeweler and have them deduce the ring size.
3) Take a ring that you know fits the ring finger and measure it against the table below.



4) Go to a jewelry store and ask them to measure your finger (it's free).

5) Wrap a piece of string around the knuckle of the finger you are interested in knowing the size of and cut it where the two ends meet. Place this against a ruler and compare it to the chart below to determine finger size. (Measure the knuckle because you will need to be able to get the ring off and on. If you would like the ring to fit tightly, order ½ a size smaller than the knuckle size.



6) The chart below may be used to determine finger size, however print size must be correct;
