Is a Lab-Grown Engagement Ring Worth Buying?

An engagement ring isn’t just about carat size. It’s important to understand all components making up an engagement ring, which would help ensure a valuable purchase.

The first component to pay attention to is the diamond. Though cut, color, clarity, and carat are all crucial, the cut is the one affecting the brilliance of a stone the most. Thus, a well-cut diamond would usually seem more brilliant than a bigger one with a poor cut.

The certification is another component to think about. Independent diamond reports issued by trusted laboratories would give you an objective view of the features of your engagement ring.

The settings shouldn’t be ignored either. Not only do they make a ring look nice, but they also affect the security of a diamond and its suitability for everyday wear. The choice of a precious metal is the last thing worth paying attention to when it comes to choosing an engagement ring.

Even as fashion trends change over time, classic designs have always been a part of the most in-demand engagement rings.

Solitaire rings have never failed to stand the test of time, with their timeless design where the center diamond takes center stage.

Oval-cut diamonds are much desired because of the elongated look that gives the impression of a bigger stone coupled with the dazzling effect of the cut.

For those wishing for added sparkle without overshadowing the center diamond, hidden halo designs have risen in popularity. The ring features a circle of diamonds set underneath the center stone.

The emerald cut diamonds have always been favored by buyers that prefer understated elegance. With their long and step-cut facets, they offer an elegant and contemporary look to the buyers, whereas three-stone rings are always popular among couples.

How Much Should You Spend on a Lab-Grown Engagement Ring?

Contrary to the popular belief, not everyone can, and should spend their three months’ salary for getting a diamond engagement ring. A perfect engagement ring doesn’t always have to be an expensive one, and it can fall under these budgets:

Under NZ$2,000: Look for a classic solitaire design with lab-created diamonds ranging from 0.30 to 0.70 carats that fit well with minimalistic designs.

NZ$2,000-$4,000: An affordable yet desirable option that allows for diamonds of 0.75 to 1.50 carats along with more setting options like invisible halo and pave bands.

NZ$4,000-$7,000: Perfect for those who are searching for diamonds of 1.50 to 2.50 carats, better color and clarity, or custom made rings.

Which Diamond Shape Gives You the Most for Your Budget?

All diamond shapes do not necessarily give the same wow factor for the same price.

The round brilliant cut remains the standard for brilliance, but it also tends to cost more. If you’re looking for maximum size per budget allocation, then shapes such as the oval, pear, or radiant can appear much larger than a round diamond of equal carat weight.

There is also a completely different allure in an emerald cut diamond that emphasises elegance over brilliance, and a cushion cut diamond is very elegant and affordable.

In the end, the most desirable shape is one that works well for you personally and budget-wise, rather than a fleeting trend.

What to Avoid When Buying an Engagement Ring

While it may be tempting to focus solely on the size of the diamond, doing so usually involves neglecting those aspects which can have the biggest influence on the beauty and durability of the piece.

Customers frequently understate the significance of the quality of cut, forget to check out the certification, or base their choice of the setting on aesthetics alone without taking into account whether it is suitable for everyday wearing. Some people also get carried away with current fashion rather than choosing timeless designs.

Choosing carefully will almost certainly result in making a better decision.

Choosing a Ring You’ll Love for Years to Come

The engagement ring is certainly one of the most important purchases that you’ll have ever made, which means it might pay off to go beyond trends and marketing claims. The perfect lab grown engagement ring for you won’t be the biggest and the fanciest, but a ring that suits your taste and fits your budget perfectly can be considered as such.
