Can I return it if I am not satisfied?

The answer is YES most of the time though.

Most major online diamond stores offer a 30 day money back guarantee for all loose diamond purchases, as long as you did not customize the order.

Any customized orders are often not refundable; they may give you their company's store credit that can be applied towards future purchases with their companies.  However if the order is for loose stones that are not customized, it is often accompanied by a 30 day money back guarantee.

Please check with each store before finalizing the purchase. Always check out the store reviews, ratings and their Return policies.
