These gems are some of the Brazilian Alexandrites which has turned out to give us some really good gemstones, they have the good color change and good clarity. These gems are 1@ .50 1@ .49 1@ .52 and 1@ .48 carats each, they are all around a half carat each, they measure: 5.0mm each. cut in the trillion shape, clarity: VS2, I bought this material in the rough and had it cut. These are the last of this material, I have a 5x7mm oval cut from the same rough.
