Bluestone is a very good online site to purchase Gold/Diamond Jewellery or Coin. I also purchased the 1gm of Gold Coin on the day of Dhanterus-2015 and also got a 10% of cash back on my purchase amount.
I noted some value points from the site and with my experience with Bluestone:
They genuinely/honestly offers discounts either on making charges or cash back(because of price comparison before and after offer, and found its different).
They delivered the product before the promised time with the correct ordered product.
Their Courier partners are also genuine.
Prices are genuine and correct on every items selling on the site(Correct differences are showing for 18K, 22K or 24K Items with different match setting of Diamonds with it).
Online payment mode is also safe & secure. Its done through their their payment partner PAYTM(because I did my payment online).
After got my product, I got my cash back in my account with a validity of 1 Year to purchase and use my cash backs.
Their Customer Care Support also gave the correct information to me regarding the delivery period, charges, offers etc.
Recommend to all my dears, that go with this site to purchase the jewelry/coin and feel the experience.
You can ask/comment for queries, if any.
