How many Feng Shui crystals can be in one room?

Hahaha! Honestly I don't know. I think that depends on personalize from each person. I created few frames with the shape of swan, hummingbird, etc. I just wanted to fill these frames with the beautiful crystal ball prisms. Somehow I wanted to maintain along with numbers such as 3, 6, 9, 18, 27, 36, 45, 60, 72, 81, 90 (multiple/factor of 9). I found that MerryNine 300mm/1.18" has very good quality. I bought from the other branch as well but I found that MerryNine 300mm/1.18" has better quality. I'm not advertising for anyone. I just wanted to share my good/happy experience so the other customers won't have to go through disappointment with their purchasing.

I need to get more of the orange 30mm. Is that possible?

Try to contact the distributor. Guess you would get that information from Amazon, but only the distributor would be able to tell you how to get orange 30mm in the volume you need.

Do you recieve the exact colors shown in ad? Are these coated color or solid all the way through?

I did receive the colors shown in the ad. They were very vibrant and bright when I first got them and have seemed to fade quite a bit since hanging them outside. I am not positive but I don't think the color is solid all the way through due to the fading. I still love them!
