As opposed to diamonds, which are typically thought of as investment gemstones, a fine 2 carat white sapphire can appreciate in value over time. The clarity, cut, and origin of the stone are all factors that affect its value. A 2 carat white sapphire might be a very appealing choice for people looking for a special and exquisite gemstone with appreciating potential. But keep in mind that gemstones do not always appreciate in value, so your decision to buy one should be based mostly on its beauty and sentimental worth.
