I bought this diamond http://m.briangavindiamonds.com/diamonds/diamond-details/0.548-i-vs2-round-diamond-ags-104057888042#&ui-state=dialog.. In bedroom lighting it barely sparkles at all even during the daytime. In the bathroom is sparkles very impressively. Kitchen pretty good. Sunlight amazing. In outdoor shade it does not sparkle much. In indoorshade it doesnt sparkle. Is this jormal? Particularly in the bedroom i was surprised there wasnt much sparkle. It is a brian gavin signature ags 000. So i figure its as good as its going to get. Any opinions? I dont have anything to compare it to.
