14K vs. 18K gold: Which is better for daily wear?

Both 14K and 18K gold are far more durable than pure gold due to the addition of alloy metals (such as copper, silver, nickel, zinc,...). However, the higher concentration of gold in 18K jewelry makes it softer and less durable than 14K gold. This makes 14K jewelry better for everyday wear if you’re concerned about scuffs and scratches.

Are moissanite and lab diamonds the same gemstone?

No, lab-grown diamonds and moissanite are not the same. Lab-grown diamonds are made of pure carbon, which are identical to mined diamonds; while moissanite is composed of silicon carbide. To the untrained eye, moissanite looks like a lab diamond. This is why some consumers choose moissanite as a diamond alternative for more affordable engagement rings and wedding bands. However, moissanite is graded differently and has a lower market value than both natural and lab diamonds.

Are your diamonds certified?

Yes! All of our lab diamonds are certified by IGI—the globally recognized jewelry certification lab that assesses and grades lab diamonds, natural diamonds, and many other gemstones.

Color

Color refers to the natural tint of a diamond. The closer the diamond is to “colorless” the rarer it is. The industry standard to grading color in a diamond is to assign a letter grade from D (colorless) to J (nearly colorless)

J I H G F E D

Clarify

Most diamonds have imperfections in the form of internal flaws and surface blemishes. These imperfections are graded on a scale of FL (flawless) to I1-I3 (included). FL diamonds are the rarest and hardest to find.
