You'll get more replies if you post the certificate, any additional photos/videos, details on the ring itself (metal type, side views and close up to see the workmanship), and the price. You can always upload photos to Imgur and post the link if uploading them here is confusing, I think videos need to be posted to Imgur or similar. Also, flag your post and ask the moderators to move it to RockyTalky if natural and Lab Grown Diamonds if lab, those subforums are much more trafficked.
