Gemstones & Diamonds Glossary | Cuts, Clarity, and Stone Types Explained

Diamond

A diamond is the world’s most iconic gemstone — prized for its unmatched brilliance, strength, and symbolism of eternal love. As the hardest natural material on Earth, diamonds are a timeless choice for engagement rings and fine jewelry. At Mimiso, we offer both natural diamonds and lab-grown diamonds, ensuring ethical sourcing without compromising beauty.

The 4 Cs of Diamonds (Cut, Color, Clarity, Carat)

Understanding the 4 Cs is essential when evaluating a diamond’s beauty and value:

Cut

The most important factor in a diamond’s sparkle. A well-cut diamond reflects light brilliantly, regardless of size.

Color

Diamonds are graded from D (colorless) to Z (light yellow or brown). The less color, the rarer and more valuable the stone.

Clarity

Refers to tiny internal marks (inclusions) or surface blemishes. Most diamonds have natural inclusions that do not affect beauty.

Carat

A measure of weight, not size. Larger carat weight often means a bigger diamond — but cut and setting can impact visual size.

Lab-Grown Diamond

A lab-grown diamond is created using advanced technology that replicates the natural diamond formation process. These diamonds are chemically, physically, and optically identical to mined diamonds — but are more sustainable, traceable, and conflict-free. Mimi So proudly offers lab-grown diamonds as a modern, ethical alternative.

Gemstone Cuts

The cut of a gemstone affects its shape, light performance, and overall style. Popular gemstone cuts include:

Round Brilliant – Classic and high sparkle.

Emerald Cut – Sleek, rectangular with a mirror-like effect.

Cushion Cut – Square with rounded corners; soft and romantic.

Oval Cut – Elongated and elegant, flattering on any hand.

Pear, Marquise, and Radiant – Unique shapes that add personality and flair.

Natural Gemstone

A natural gemstone is formed organically over millions of years within the Earth. These stones may contain natural variations or inclusions, which enhance their uniqueness. Mimiso sources natural gemstones with integrity, offering authenticity and rarity in every piece.

Birthstones

Birthstones are gemstones associated with each month of the year, believed to bring good luck, protection, or personal meaning. The birthstones for each month are:

  • January: Garnet
  • February: Amethyst
  • March: Aquamarine or Bloodstone
  • April: Diamond
  • May: Emerald
  • June: Pearl, Alexandrite, or Moonstone

FAQs

Both are chemically and visually identical. The key difference lies in origin — natural diamonds are mined from the Earth, while lab-grown diamonds are created in a controlled lab environment. Lab-grown diamonds are more ethical and sustainable.

Diamonds are the most traditional choice due to their hardness and symbolism. However, sapphires, moissanites, and other durable stones are rising in popularity for their uniqueness and personal meaning.

Natural gemstones may include inclusions or slight variations in color. Certifications and trusted retailers like Mimiso can verify gemstone authenticity and sourcing.

Round brilliant, emerald, cushion, and oval are among the most loved. Each cut highlights a different aspect of a gemstone’s beauty and personality.
