- _***m (1)- Feedback left by buyer.Past 6 monthsVerified purchaseI need to duplicate this ordewr, to 6 total. 4th review, same as the previous 3 !!!!! Another great purchase, quality exceeding my expectations. Beautiful stone. Package arrived in perfect condition very quickly. I am still amazed at the color change as it is dramatic, not subtle... All the stones I have bought so far, have made a significantly higher value to the low quality gems I have replaced. Quality exceeds the photo as described in the ad, and the packaging made sure they arrived safely.Reply from: gemtasy- Feedback replied by seller gemtasy.- Feedback replied by seller gemtasy.Thank you for feedback and continuously supporting our store.
