Certification: I'm located in Pakistan there's no good lab available here, like GIA or GRS, here only some local labs are available and they're lame because in the past I've noticed that there results aren't accurate sometimes becuase they are using outdated devices, they provide you with a small report card which and there isn't any online verification for that result, so firstly I'm responsible for my words, if there is any treatments done to the stone I will definitely disclose that, so I suggest the buyers if they need certificates then they should create in their country in some good lab after receiving the items. Any questions feel free to contact. As with all my photos, there is no editing or color enhancement.This item is in the category "Jewelry & Watches\Loose Diamonds & Gemstones\Loose Gemstones". The seller is "gemsbazaar" and is located in this country: TH. This item can be shipped worldwide.
