Quality Assurance & Warranty

At ISAGO, we take pride in jewelry craftsmanship. Each piece undergoes strict quality checks. If you experience damage to your purchase due to manufacturing, please contact us so we may evaluate your piece. Email with photos, a short video, and a description of how the damage occurred. If we find the damage is not repairable via the provided images, we may not accept the item back for an evaluation.

Lab-Grown Diamonds Warranty
ISAGO lab-grown diamonds come with a one-year warranty against manufacturing defects. We use internationally recognized 4Cs diamond grading, ensuring the color, clarity, and cut meet the highest standards. In the unlikely event of any manufacturing defect, after assessment, we will replace the diamond. 

Jewelry Warranty:
ISAGO provides a one-year warranty for gold jewelry against manufacturing defects during the one-year warranty period. 

  1. Lab Grown diamond & Stones warranty only applies to diamonds and stones up to 0.100ct in size. The warranty does not apply to any diamonds above 0.100ct and stones. 
  2. Resizing warranty is applicable to only resizable rings. This warranty only covers resizing up to +/- 4HK sizes from original size. If a ring needs a resizing above 4HK sizes, gold charge will be applicable as additional gold is needed to resize the ring. In order to maintain the aesthetic value of the ring, it is recommended to resize the ring at +/- 2HK. 
  3. ISAGO can help with repolishing and resetting your jewelry after warranty period, with a small fee.
