Bella has always been my favorite diamond simulant. I used to buy it when it was offered on Shop At Home.
IMO it is far superior to diamonique or absolute. I'm not even sure HSN sells absolute anymore, do they? Haven't seen it offered in a long time.
But you do get what you pay for and you have to pay attention to the carat weight. Many times they list the carat weight in CZ weight, not diamond weight which is less. Typically they will have the diamond equivalent on the screen.
I have been very happy with all BL that I have purchased with the exception of one adjustable bracelet. When it arrived, the CZs were barely visible and it just looked like a sterling bracelet.
Also be aware that JTV does not refund original s/h. But you can almost always find a code for reduced s/h or free s/h.
