Due to space limitations we recommend you use no more of 40 characters, which includes spacing. This character limit was agreed upon as it works best with all crystal sizes and designs, and won’t take away from your chosen image.Even though we suggest you use no more than 40 characters including spaces, you are able to add more characters if necessary. If over the 40 character limit, add your additional text in the 'Special Instructions' section on the order page. However, please note that on smaller crystals, the extra text may compromise the image as there will be less surface space for the 3D engraving. We do not charge any more if you exceed 40 characters.
