Expert Tip
"When shopping for gemstones online, always request both the carat and dimensions of the stone."
Every Gemstone Is Unique
As with diamonds, the carat weight of gemstones doesn’t necessarily affect the stone’s size. Depending on their origins and unique elements, two stones from the same variety and size may have different densities and therefore, different carats. When selecting a gemstones for an engagement ring or gem set jewellery, consider the size rather than carat.
