Hey there! As a supplier of Oval Moissanite Diamonds, I often get asked about the girdle thickness of these sparkly beauties. So, I thought I'd write this blog to share everything you need to know about it.

First off, let's understand what the girdle of an Oval Moissanite Diamond is. The girdle is the outer edge that separates the crown (the top part) from the pavilion (the bottom part) of the diamond. It's like the waist of the stone. The thickness of this girdle can vary, and it plays a crucial role in the overall look, durability, and value of the Oval Moissanite Diamond.

Why Girdle Thickness Matters

The girdle thickness affects several aspects of the Oval Moissanite Diamond. One of the main things is its durability. A very thin girdle may make the diamond more prone to chipping or damage during setting or everyday wear. On the other hand, a too - thick girdle can make the diamond look less brilliant and can also add unnecessary weight, which might increase the cost without adding much to its visual appeal.

Another important factor is the way light interacts with the diamond. The right girdle thickness helps in proper light reflection and refraction, which is what gives the Oval Moissanite Diamond its amazing sparkle. If the girdle is too thick, it can block some of the light, reducing the diamond's brilliance.

Measuring Girdle Thickness

Girdle thickness is usually measured in millimeters, but it's often described in relative terms like thin, medium, thick, or very thick. Jewelers use special tools like calipers to measure the girdle accurately. When you're buying an Oval Moissanite Diamond, the certificate usually includes information about the girdle thickness.

Here's a general breakdown of the common girdle thickness descriptions:

  • Thin: A thin girdle is usually less than 0.3mm. While it can give the diamond a delicate look, it needs to be handled with care during setting to avoid damage.
  • Medium: A medium - thick girdle ranges from about 0.3mm to 0.5mm. This is often considered the ideal thickness as it offers a good balance between durability and brilliance.
  • Thick: A thick girdle is over 0.5mm. It provides more protection but might make the diamond look a bit duller if it's too thick.
  • Very Thick: A very thick girdle is significantly over 0.5mm. This can make the diamond look bulky and can also increase the cost due to the extra weight.

Choosing the Right Girdle Thickness

When you're in the market for an Oval Moissanite Diamond, you need to consider your personal preferences and how you plan to use the diamond. If you're getting an engagement ring that you'll wear every day, a medium - thick girdle might be the best choice. It'll be durable enough to withstand daily activities while still looking brilliant.

If you're going for a more delicate piece of jewelry that won't be exposed to a lot of wear and tear, a thin girdle can give the diamond a more elegant and refined look.

Comparing with Other Shapes

It's interesting to compare the girdle thickness of Oval Moissanite Diamonds with other fancy - cut moissanite diamonds. For example, Pear Moissanite Diamond often has a different girdle thickness distribution. The pointed end of the pear shape might require a slightly different approach to girdle thickness to ensure its durability.

Heart Moissanite Diamond also has unique characteristics. The curves and the cleft of the heart shape mean that the girdle thickness needs to be carefully considered to maintain the shape's integrity and brilliance.
