The traditional gemstones are ruby, emerald and blue sapphire. Because of their lasting appeal and distinguished history, ruby, emerald and sapphire are more valuable than other colored gemstones. Generally, ruby and emerald are also priced higher than a comparable quality sapphire due to rarity. For a one-carat stone of average to good quality in the varieties in this category, you can expect to pay between $250 and $10,000 per carat. Of course truly fine gems will cost more.The new classics are gemstones that are the rising stars of gemstone jewelry: tanzanite, tourmaline, aquamarine, imperial topaz, and tsavorite garnet. These gemstones are sometimes available in standardized sizes but you really should look at some fine larger single stones to see why they have so many fans. Gems in this category range between $50 to $1,000 per carat for an average to good quality one carat stone, with a good example of tsavorite easily reaching $3,000 per carat.Connoisseur gems are gemstones that have a more specialized market because they are more rare. These gemstones include black opal, jadeite, pink topaz, chrysoberyl cat's-eye, fancy colored sapphires, and rare stones like demantoid garnet and alexandrite. These gemstones are highly prized and prices range from $250 to $5,000 per carat, although alexandrite with a good color change will command at least $10,000 even in a one-carat size.Then there are the affordable gemstones, which combine great color with a surprisingly reasonable price and good availability. These gems include some old favorites and some new gems: amethyst, white opal, citrine, ametrine, peridot, rhodolite garnet, blue topaz, iolite, chrome diopside, kunzite, andalusite, and many ornamental gemstones such as lapis lazuli, turquoise, onyx, chrysoprase, nephrite jade, and amber. Prices for these gemstone range between $5 and $100 per carat for a one carat stone.In every variety, especially the more expensive ones, you should expect to pay more for matched pairs, sets, and special shapes and cuts.
