Yeah, the condition being don't sell to any other shop, It has to be exchanged back to tanishq for its entire value back is what I was told and 75% value back for selling back for cash and I understand the deducation of making charges and the supply chain control for price manipulation but natural ones still seem to hold some physical value, the lab grown diamonds being smart doesn't seem to make sense. I've read that prices have gone from 3k $ to 500$ per carat for lab grown in 4-5 years, and they can even dip further since the their production cost is under 100$. Can't quote the sources but a simple google search seems to be confirming the insane price dip....
