Hi! I have purchased from:
Wuzhou Tianzuan Jewelry Co. LTD
Thru my Alibaba app.
They are located in China. Buy their 6A+ Cubic Zirconia gemstones. The quality of this cubic zirconia is the best I have seen. Their 8A+ rivals diamonds. The quality of their cutting is absolutely beautiful. I was thrilled with their cutting.
I bought these colors:
Diamond Gold
Diamonds L Pink
Their special diamond white color mix in the 6A+, dead ringger for a DEF diamond.
Ask for Vivi, as she is the manager.
Her phone number is: +86-18977409219
Also, I purchased their lab created Zambian colored emeralds with inclusions. If I didn’t know better, I would have sworn it was a mined emerald.
I hope this helps!
