This standard round brilliant is a beautiful gemstone. It has a great, well saturated red in yellowish light, but to its eternal regret, it does brown out in the bluer, natural light of days. I forgive it though and gave it a really nice name of mahogany. But I am having second thoughts about the name, since the oranges the brown out seem better suited for mahogany. So I guess I will have to leave it at brown red for this wonderfully rich, eye clean stone with fine crystal. It weighs 8.23 carats.
