Diamond Education & Buying Process

What’s the difference between 14K gold and 18K gold?

Both 14K and 18K gold are commonly used in fine jewelry, but they differ in gold content, durability, color, and value:

1. Gold Content:

  • 18K gold is 75% pure gold (18 out of 24 parts), while 14K gold is 58.3% pure gold.

  • The higher gold content in 18K gold gives it a richer color and a more luxurious appearance.

2. Durability:

  • 14K gold contains more alloy metals, making it harder and more scratched-resistant.

  • 18K gold is slightly softer but still durable enough for everyday wear if properly cared for.

3. Hypoallergenic Properties:

  • 18K gold contains fewer alloy metals like nickel, making it less likely to cause allergic reactions.

  • 14K gold may contain more nickel, which can trigger skin sensitivity in some individuals.3. 

4. Value Retention:

  • 18K gold retains its value better due to its higher gold content.

5. Color & Finish:

  • 18K gold has a deeper, more vibrant yellow hue, while 14K gold has a slightly lighter tone.

6. Practicality:

  • If you lead an active lifestyle, 14K gold may be a more practical choice as it resists scratches better.

Both options have their advantages, and the choice depends on your lifestyle, budget, and aesthetic preference.

What’s the difference between CVD and HPHT diamonds?

CVD (Chemical Vapor Deposition) and HPHT (High Pressure High Temperature) are the two primary methods used to create lab-grown diamonds.

1. CVD Diamonds:

  • Created in a controlled environment using a gas mixture to form carbon layers on a diamond seed.

  • Typically whiter and free from metallic inclusions, making them a popular choice for fine jewelry.

  • Often require post-growth treatments to improve color.

2. HPHT Diamonds:

  • Grown by mimicking the natural conditions under which diamonds form in the earth.

  • Can have a slightly different crystal structure compared to CVD diamonds.

  • Some HPHT diamonds may show metallic inclusions due to the process.

Both CVD and HPHT diamonds are 100% real diamonds, possessing the same physical, chemical, and optical properties as natural diamonds.

General Diamond Questions

Are lab-grown diamonds real diamonds?

Yes. Lab-grown diamonds are 100% real diamonds, identical to natural diamonds in every way except for their origin. They possess the same chemical, physical, and optical properties as mined diamonds.

Do lab-grown diamonds hold their value?

While lab-grown diamonds are more affordable than natural diamonds, they do not hold value in the same way because they can be produced in unlimited quantities. However, if you're purchasing for beauty and quality rather than resale, lab-grown diamonds offer incredible value.
