Emerald is one of the big three colored gemstones, alongside sapphire and ruby. Emeralds come in a variety of green tones ranging from yellowish-green to bluish-green, and often have a satiny "glowing" appearance in the light. Tiny inclusions in the stone actually help create this glowing satin effect. The finest emeralds were historically mined in Colombia, but today many high grade stones are also found in Zambia and Brazil, among other places. Emerald is the birthstone for May.

Ruby is one of the classic big three precious gemstones alongside sapphire and emerald. Ruby is actually of the same mineral family as sapphire, corundum. Gem-grade ruby is incredibly rare and highly valued right now, with prices increasing every year. The finest rubies come from Myanmar (Burma), but export controls have made these rubies extremely rare. Other sources of very fine rubies include Madagascar and Thailand. Jewelry shoppers must be very careful when purchasing rubies -- most rubies on the market are "glass-filled", which means the stone may be mostly glass with some traces of natural ruby mixed in. We do not deal in glass-filled rubies, all of our rubies are natural with at most routine heat treatment. Ruby is the birthstone for July.
