Insurance & Care
NO, we do not provide cleaning services or external care for the jewelry sold on our website, the reason behind this is that we already offer the lowest price possible on our product. We do not include any middleman cost or extra margin on our product. Including any other cost like cleaning would not be financially feasible for our business.
PS: Over time, it becomes necessary to tighten the prongs on all rings and occasionally even replace them to prevent diamonds from becoming loose or falling out. It is strongly recommended that all jewelry owners have their settings examined by a professional at least once every 9-12 months.
Our warranty covers any issues with your product as soon as you receive it. It also includes fixing loose prongs, polishing, and rhodium plating within a seven days of purchase. We guarantee our products are defect-free, but if you find any issues, please contact us.

Yes – lab-created diamond will be accompanied by an independent laboratory (GIA/IGI/GCAL) report detailing its “4 Cs” – cut, color, clarity, and carat weight. If your diamond is mounted into jewelry, it will also be accompanied by an independent laboratory.
Please note GIA, IGI and GCAL does not provide cut ratings for fancy cut stones, i.e any shape outside of round. That’s why some of the fancy shapes does not have the cut grade listed on the website.
