Krásný kámen který mi byl doručen v parádním boxu.
Jsem velmi spokojená s obchodem děkuji.
Good looking on time arrive gem is real
This stone exceeded expectations. It looked just like the pictures and is beautiful. I purchased it as a gift and it was loved. Not only was the stone beautiful, the presentation box it was shipped in was very nice. The certification paperwork was packaged inside the box with the stone. This made this special gift even better. I had a concern after I made the purchase and contacted Sosna sales via email late one night. They responded early the next morning to address my concerns. I will definitely purchase from Sosna Gems again and I recommend the beautiful Ametrine stone to everyone.
I received not only my gemstone soon after ordering, but also a beautiful original case, certificate, care recommendations and a nice gift. I know several suppliers, this one is at the top of the professionals. Thank you to him
Gorgeous ring, lovely service!!
An execellent piece of Emerald received. Its exactly the quality that I perceived. I am more than happy with the packaging & delivery standards. Sosna would be my most preferred store for gemstones & I highly recommend it.
Nice pendant, good manufacturing quality. The stone is fantastic. Great service
Nice shop
Beautifull gemstone
This was my first time ordering here, and I was pleasantly surprised. The communication was warm and very helpful, and everything was explained clearly. My order arrived safely and beautifully packaged. I truly appreciate the care and professionalism. I would feel comfortable shopping here again.
The sapphire is absolutely beautiful. I was really surprised by how much the color changes in different lighting. It looks one way in daylight and completely different under warm indoor light. It’s fascinating to watch, and I can’t stop turning it in my hand. I’m very happy with the quality. Thank you.
