Good vs Bad Lab Diamonds

 Here are 6 facts about lab diamond quality that you should know before you buy.

Fact #1: There Are Gorgeous Lab Diamonds Available

Stone Lab Diamonds only sells diamonds of Type IIa purity, the rarest diamond type with a perfect carbon structure.

Type IIa diamonds are whiter and sparkle better than 99% of earth-extracted diamonds. These beautiful lab diamonds are icey white, have no fluorescence, no milkiness, a super clean crystal material, and a noticeably brighter appearance, even to the naked eye.

Advancements in diamond scanning and laser cutting have also resulted in lab diamonds with perfect ideal cuts, no bow ties, and no paneling, all at prices of ~50% off of equivalent quality mined diamonds.

Fact #2: Not All Lab Diamonds Are the Same

Just because two lab diamonds received the same 4Cs grading does not mean they will look the same.

High Pressure High Temperature (HPHT) diamonds with excess boron can have a blue tinge and phosphorescence. Irradiated HPHT diamonds with excess titanium and aluminum can look gray. Chemical Vapor Deposition (CVD) diamonds that were grown too quickly can look brown.

CVD diamonds with iterative growth patterns can appear lifeless and cloudy. CVD diamonds can also have black surface inclusions from excess polycrystalline. CVD diamonds grown on cheap seeds can have blurriness from crystal strain and graining.

These elements are not obvious at first glance to a non lab diamond expert. These characteristics also reduce resale value.

Fact #3: It’s Easier (and Cheaper) to Grow Bad Diamonds

Beautiful lab diamonds take patience. The faster you grow a diamond, regardless of method, the worse the quality. Growing colorless, high clarity diamonds is much more time consuming and expensive than growing dark, heavily included diamonds.

While diamond growth technology has improved, many growers who are capable of producing nice diamonds actively choose to grow ugly ones because it is so much cheaper to do so.

Some growers take short-cuts like HPHT treatment, irradiation, and bad cutting methods to produce as many lab diamonds as possible. But those ugly diamonds are not worthy of an Stone Lab Diamonds client.

Fact #4: Bad Lab Diamonds Sell on Budget E-Commerce

There are a number of nascent diamond growers around the globe contributing to an abundant supply of bad lab diamonds. These diamonds are grown quickly and cheaply and then sold on budget ecommerce sites to unsuspecting members of the public.

High quality CVD goods can cost the manufacturer 2-3X more than low quality CVD. These goods trade at significantly different wholesale pricing, and hence, are offered to the public at different prices. A 2 carat F VS1 round may be 30% more expensive than another on the market, and the reason often lies beyond the cert.

Ugly lab diamonds cannot sell through discerning, luxury retailers like us. Here at Stone Lab Diamonds, we have relationships with the best growing facilities in the world and do not buy from low quality producers.

Fact #5: An Expert Should Look at Your Diamond

It’s not enough to have access to a return policy or an inexperienced customer service agent who looks at a video for you. A lab diamond expert should inspect your diamond before you buy, no matter what.

Our Diamond Concierge team are among the most knowledgeable people in the entire lab diamond industry. Each member of our team has hundreds, if not thousands, of hours of inspection time with lab diamonds of varying quality, and we know what we’re looking for.

We can confidently identify unnatural color defects, crystal material, undesirable inclusion types, poor make, and other characteristics that deem a lab diamond unworthy of our clients and our buy-back program.

Fact #6: The Lower the Price, the Higher the Risk

If you buy a lab Grown diamond from an online wholesaler or budget ecommerce site, you are often required to pay for the diamond up front, completely sight unseen. Most lab diamonds sold online are not inspected prior to shipment. You may get a great price, but you are taking a significant risk that the diamond you are buying is undesirable.

At Stone Lab Diamonds, your five-star experience is low risk. Without any financial obligation, we will curate, inspect, and obtain media of some of the best diamonds on earth.

Once you’ve chosen a lab diamond with us, we only require a 20% deposit to reserve the diamond and design your ring. We’re so confident in our quality that we offer a 30-day return policy, lifetime trade-in, and guaranteed resale.
