What are some popular types of gemstones?

Gemstones fall into two broad categories: precious and semi-precious. Despite their name, precious gemstones are not necessarily the rarest or most expensive stones but rather the most sought-after and valued overall. The most popular precious gemstones are known as the big four: sapphires, rubies, emeralds, and diamonds. Among the others are opals and pearls. Practically all other gemstones not in that category are considered semi-precious. The most popular of these are agate , rose quartz , black onyx , and the 12 birthstones . There are other ways to classify different gemstones, such as natural, synthetic, and imitation gemstones. Organic and non-organic designations are sometimes used for formations such as fossilized tree resin, better known as amber.

What are some popular gemstone cuts?

Gemstone cuts affect the overall appearance of the gemstone and give it a unique shape. Some cuts have many facets to reflect lots of light, whereas others let the natural color steal the show. Here are a few of the most popular cuts. Round-cut gemstones : Popular for engagement rings, these appear round from a top-down view, with lots of facets for a sparkly, brilliant ring. For an angular alternative, try an octagon cut. Marquise-cut gemstones : Instantly recognized for their elongated shape, marquise cuts are elliptical with two pointed ends, which can make your finger appear longer and slimmer. Trillion-cut gemstones : Also known as a trilliant cut, trillions are triangular shapes with curved or non-curved sides and many variations. Oval-cut gemstones : Like an elongated round cut, these excel at showing off brilliant, fiery gemstones such as diamonds and moissanite. Pear-cut gemstones : Sometimes referred to as teardrop or pendeloque cut, these blend the top pointed part of a marquise with the circular bottom of a round cut. Emerald-cut gemstones : Not just for emeralds, the emerald cut is rectangular with the corners cut off. Their signature look is complete with chiseled step cuts along the sides for a commanding appearance. Princess-cut gemstones : Square princess cuts maximize brilliance with stunning patterns in a timeless design. Princess cuts are popular for engagement rings and frequently include decorative pavé gemstones. Cushion-cut gemstones : These stunners are also square but have rounded corners for a smoother, romantic feel. Cabochon-cut gemstones : Rather than faceted, cabochon cuts are polished and shaped. Jewelers most often use them with opaque gemstones such as opal and jade.

What are the 12 birthday gemstones?

Rooted mostly in astrology and the zodiac, each birthday month is associated with a traditional and a modern gemstone. Both modern and traditional birthstones have their own meanings . January: Garnet for both modern and traditional February: Amethyst for both modern and traditional March: Traditionally bloodstone and aquamarine for modern April: Diamond for both modern and traditional May: Emerald for both modern and traditional June: Traditionally pearl and alexandrite for modern. July: Ruby for both modern and traditional August: Traditionally sardonyx and either peridot or spinel for modern September: Sapphire for both modern and traditional October: Traditionally opal and tourmaline for modern November: Traditionally topaz and citrine for modern December: Traditionally turquoise or lapis lazuli and zircon, blue topaz, or tanzanite for modern

What are some of the rarest gemstones?

Although there are many rare gemstones—such as diamonds, emeralds, sapphires, and rubies—a few are especially uncommon. These include tanzanite, black opal, red beryl, and alexandrite. Tanzanite and alexandrite are beloved for the way they change color in the light: Tanzanite changes between blue, violet, and burgundy; alexandrite turns green in the light and red in the dark. Opal gemstones by nature are rare, but the black version appears as a cosmic midnight sky found almost exclusively near Australia. Red beryl is a brilliant scarlet born out of specific environmental conditions.

How are gemstones graded?

Gemstones are graded according to rarity using the four Cs: color, clarity, cut, and carat. The higher grades fetch higher prices because they are considered rarer overall—but grades are used more as guidelines for choosing gemstones rather than head-to-head rankings. To better understand grading: Color refers to the gemstone's hue, tone, and saturation, with bold, rich colors often earning higher grades. There are some exceptions, like diamonds and other clear gemstones, which are prized for being nearly colorless. Whether you’re choosing gemstones for jewelry making or finely crafted jewelry , consider what color works best for your skin tone and use color as a guide. Lower-rated gemstone colors like pink rubies and baby-blue sapphires might turn more heads than the rarer, pure red or blue versions. Clarity refers to the number of inclusions in the gemstone, with fewer inclusions receiving higher grades. Inclusions are anything from hollow areas or fractures to other mineral imperfections that affect how light passes through the gemstone. Gems rated high in clarity are likely to have few to no fractures, meaning they are strong and well-suited for rings. Cut combines quality artistry and symmetry, significantly affecting the gemstone's brilliance and fire. Brilliance refers to how much white light is reflected; fire is the reflected colored light. Together, they create pattern and sparkle, which is known as scintillation. Each cut surface is called a facet, which should be smooth and mirror-like. More facets mean many tiny sparkles; fewer facets create more prominent flashes. Carat measures the weight of the gemstone. Weight is not equal across all gemstones because densities vary from stone to stone. For example, rubies are denser than diamonds, so a one-carat diamond looks larger than a one-carat ruby.
