A gem is a stone that is considered precious or semi-precious, particularly when it is polished or cut. Stones that have come to be defined as “gems” are well known for their unique beauty, colour, patterns, or clarity. Gemstones are also typically stones considered fine enough to use in jewellery. Gemstones and semi-precious stones are typically fashioned and prepared using a few distinct methods, and people believe that these unique ways of presenting their crystals imbue the stones with different abilities or beauty.
  • Clusters & Geodes: Some gemstones, particularly types of quartz like citrine or amethyst, will be presented in sparkling clusters. In addition to being beautiful to look at, many believe that gemstone clusters have powerful calming and purifying effects on the room where they are kept.
  • Points or Towers: If you have ever gone into a crystal shop, you are sure to have seen sleek towers of semi-precious gemstones. Those who use crystals for healing believe that this pointed wand shape is excellent for transmitting energy.
  • Slices: Stones that have beautiful marbled cross sections and patterns, like agate, will often be sold in polished slices. This allows the inner beauty of the stone to be displayed to full effect.
  • Raw or Rough: Some prefer to buy their gemstones raw as untouched chunks of stone that come from the earth without being polished or cut. The belief is that when the stones are in their natural state, you will be able to connect to their energy on a deeper level.
  • Polished or Cut: When displaying a gemstone’s clarity and brilliance, they will typically be cut into facets that allow them to refract light and show off depths of colour. This is the most popular form for gemstones being used for fine jewellery.

Like snowflakes, no two diamonds are identical. Each has its own set of unique characteristics that professional cutters strive to draw out, maximizing the beauty of the stone.

Each gem is held to a set of standards for cut, color, clarity, and carat– commonly referred to as the 4 Cs– that interact to determine the overall rating and diamond quality.

The cut, color rating, clarity grade, and carat weight can help determine diamond quality, but there’s no “right answer” to how a diamond should look. Many people in the market for a breathtaking piece of jewelry are more than willing to prioritize one factor in favor of another.
