why are rubies are valuable
Ruby is the red variety of corundum. It is quite a bit rarer than the blue gems. The rarity combined with the demand for rich red gems keeps the price very high. Among rubies though, there is no shortage of small gems, the kind used in cluster rings.hey are somewhat expensive, but readily available. The Carmen Lucia Ruby is an incredibly rare ruby due to both its size and quality. It is when you get into gems of a carat of more that they get really expensive. Good quality rubies in this size range are few and far between.
