7. What is a moissanite and a diamond?

+

Moissanite is a lab-created gemstone that resembles a diamond. It's made of silicon carbide (SiC) and has similar optical properties. Diamonds, on the other hand, are naturally occurring gemstones made of carbon. They're known for their hardness, brilliance, and rarity. Both have their unique characteristics, but moissanite is more affordable.

8. What are the 4Cs of diamonds?

+

The 4Cs of diamonds are: Cut, Color, Clarity, and Carat Weight. These characteristics determine a diamond's quality and value. Cut refers to the shape and brilliance, color grades the absence of color, clarity assesses flaws, and carat weight measures the size.

9. What are lab-grown diamonds?

+

Lab-grown diamonds are diamonds that are created in a laboratory rather than being mined from the Earth. They have the same physical, chemical, and optical properties as natural diamonds, but they are made using high-pressure, high-temperature (HPHT) or chemical vapor deposition (CVD) processes.

10. What are the different kinds of diamond shapes?

+

There are several different kinds of diamond shapes, also known as diamond cuts. Some common diamond shapes include round brilliant, princess, emerald, cushion, marquise, pear, oval, radiant, and heart. Each shape has its own unique characteristics and aesthetic appeal.

11. How can you tell that a diamond is real?

+

There are several ways to determine if a diamond is real. One commonly used method is to examine the diamond's characteristics, such as its hardness, refractive index, and ability to conduct heat. Professional jewelers also use specialized tools like loupes, microscopes, and diamond testers to assess a diamond's authenticity.

12. Is it safe to buy diamonds online?

+

Buying diamonds online can be safe if you take certain precautions. It's important to research and choose a reputable online retailer with a good track record. Look for websites that provide detailed information and high-resolution images of their diamonds. Additionally, ensure that the retailer offers secure payment options, a reliable return policy, and independent diamond grading reports from reputable gemological laboratories.

13. Are lab grown diamonds cheaper than natural diamonds?

+

Generally, lab-grown diamonds tend to be more affordable than natural diamonds of comparable quality. The price of natural diamonds is influenced by factors like rarity, mining costs, and market demand, whereas lab-grown diamonds can be produced in controlled environments, leading to lower production costs. However, it's important to note that prices can vary depending on the retailer and specific characteristics of the diamonds being compared.
