Buy Diamonds Online:

It's essential to know where to buy diamonds online if you're purchasing an engagement ring. After all, loose diamonds are the centerpiece of every e-ring, so it needs to look spectacular.

We recommend buying a loose diamond instead of preset engagement rings. Those are cut-and-polished diamonds that have not been set in an engagement ring or jewelry item.

Most jewelers offer both loose diamonds and pre-made jewelry. Unfortunately, most preset e-rings contain sub-par center stones in our experience. You'll be able to choose a diamond with the characteristics you desire if you start with a loose stone.

Buying Diamonds Online vs. Jewelry Stores:

Online shopping is a great way to find loose diamonds. Companies like Blue Nile and James Allen are well-known for offering better prices than their retail counterparts.

They also offer a broader selection of diamonds and jewelry. Blue Nile has more than 600,000 natural diamonds available at this publication.

In contrast, James Allen has almost 400,000 earth diamonds and approximately 45,000 lab-grown diamonds.

Suffice to say that it's difficult for most mom-and-pop jewelry stores to compete with that kind of purchasing power. In that case, this article focuses on the benefits of shopping online.

When shopping online, it is crucial to work with a trustworthy vendor. We've seen many internet sites come and go throughout the years. Some of them are better than others, so we'll focus on the ones that provide the best quality and overall experience.

Essential Tips for Online Diamond Buying:

It goes without saying that you're looking for the best price, and that is why you're shopping for online diamonds. Since you cannot see the diamond sparkle in person, stick with vendors who offer hassle-free returns.

Light Performance for Brian Gavin Black Diamonds.

High-resolution clarity images or video is necessary to identify the clarity characteristics. Note that these images are not a good way to ascertain diamond color grades. However, they help determine how evenly light reflects throughout the stone.

We also recommend using ASET and Ideal Scope images to judge light performance and determine the amount of light leakage. You can also use a Hearts and Arrows Scope to evaluate optical precision.

Carefully evaluating these characteristics, in addition to the details on the lab report, enable you to know precisely what you are getting for your money.

It's also a good idea to consult with an expert like Todd Gray; he's a professional diamond buyer with 35+ years of experience. In fact, we'll be highlighting the top places to buy loose diamonds online based on his recommendations below.

Best Round Brilliant Diamond Proportions:

We recommend that you use the advanced filters that enable you to fine-tune the selection criteria when shopping for diamonds online. We also recommend strictly adhering to these proportions if you're buying a round brilliant:

  • Total depth between 59 - 61.8%.
  • Table diameter between 53 - 58%.
  • A crown angle between 34.3 - 35-degrees.
  • A pavilion angle between 40.6 - 40.9 degrees.
  • An overall cut grade of GIA Excellent.
  • A girdle edge between thin to slightly thick, faceted.
  • A culet size of none.

This range of proportions produces a high volume of light return and a virtual balance of brilliance and dispersion. However, it is still necessary for the cutter to create a higher degree of optical precision for maximum light performance.

Buying Loose Diamonds Online:

You need to know the trustworthiness of online vendors if you want to purchase diamonds online. From our perspective, a few key players set the bar high, and then there is everybody else.

Low-quality sellers may sell diamonds at higher prices, offer a limited selection of diamonds, or not have certificates from top-tier gemological laboratories. Under those circumstances, you could end up spending a lot of money on a diamond that is worth only a fraction of its price.

Shop with a recommended retailer in the diamond industry to ensure that you don't experience buyer's remorse or get burned. The top places to buy loose diamonds for 2022 are as follows:

In that case, you can buy with confidence, knowing that every diamond they produce is cut to the highest standards possible. Here are some examples of Brian Gavin's stunning diamonds:

The Pinnacle of Perfection:

One of the critical factors distinguishing Brian Gavin Diamonds from the competition is their patented polishing process. The fact is that nobody can produce ideal cut diamonds of the same quality without violating the patent terms.

Unlike virtual dealers like Blue Nile and James Allen, Brian Gavin Diamonds have their own inventory. They can also cut-to-order diamonds in the carat weight, color, and clarity combination you prefer.

It's worth mentioning that Brian Gavin Black and Signature diamonds cost more than standard ideal cuts. That's because it takes up to four times longer to achieve a higher degree of optical precision.

In that case, the diamonds are more expensive, but the light performance is also better. You can use the ASET, and Hearts and Arrows Scope images to verify the superior level of precision.

Loose Diamond Buying Tips:

These tips will help you make the most of your purchase of loose diamonds.

Choose a Reputable Vendor:

Shop with industry-respected vendors to ensure you get a high-quality and reasonably priced diamond. Blue Nile, James Allen, and other trustworthy vendors sell lab-graded diamonds at fair prices.

Select Your Favorite Diamond Shape:

Narrow down the field of possibilities, start by selecting a shape that you find appealing. Many popular diamond shapes are available, including the modern Round Brilliant and classic shapes such as Cushion, Emerald, Oval, Pear, Princess, and Radiant Cuts.

Don't Sacrifice Cut Quality:

There are four pillars of diamond grading: Cut, Color, Clarity, and Carat. It's essential to be familiar with the 4C's when shopping for diamonds. This will ensure that you don't pay too much for poor-quality diamonds.

The Cut is the most critical factor of the Four C's. It can be challenging to discern slight differences in clarity, color, and carat weight, especially in mounted diamonds.

In contrast, it is nearly impossible to conceal a poorly cut diamond. For that reason, we recommend only AGS Ideal or GIA Excellent cut diamonds.

Focus on Eye-Clean and Near-Colorless Diamonds:

It's essential to remember that diamond grading occurs in laboratory conditions, under specific lighting, and magnification. Under those circumstances, it's relatively easy to distinguish slight differences in clarity or color.

In contrast, there is a limit to what is visible to the naked eye under normal conditions. In that case, slight differences in Color and Clarity are not likely to be visible.

Generally speaking, we recommend VS2 clarity diamonds in the color spectrum of D-E-F colorless to G-H-I-J near-colorless. That combination of characteristics creates a look that most people find appealing. After all, it should face-up eye-clean and white under standard lighting.

Some people prefer diamonds that are warmer in color, and that is a matter of preference. Be aware that the color of the metal that touches the edge of the diamond can influence your perception of color by one grade.

For example, a G-color diamond set in white metal prongs looks more like F-color. In contrast, a G-color diamond set in rose gold, or yellow gold prongs, is likely to look closer to H-color.

You might drop to SI1 clarity to afford a larger diamond or decrease cost. However, most SI-1 clarity diamonds are not eye-clean in our experience. In other words, we rarely need magnification to see the inclusions in SI1 clarity diamonds.

In contrast, we need 10x magnification to locate the inclusions in VS-2 clarity diamonds. Consequently, the inclusions within VS1 clarity diamonds and higher will not be visible without magnification. In that case, you don't need to spend more on clarity since it won't be readily and immediately visible.

Diamond Grading Reports and Certificates:

It is essential to verify the characteristics for valuation purposes when buying diamonds. The AGS and GIA are the most reliable gemological laboratories, and we consider them to be top tier.

In our opinion, other gemological laboratories, such as the EGL, IGI, and GCAL, are second-tier operations. Consequently, diamonds graded by those laboratories command a considerable discount on the wholesale level.

Suffice to say that not all diamond grading certificates are considered equal by the trade. For that reason, we recommend you stick with diamonds graded by the AGS or GIA because they are the most consistent and respected.

There are distinct differences between the AGS and GIA gemological laboratories. First, the labs measure certain facets slightly differently. Then, the GIA-GTL rounds of the measurements for critical facets like the table diameter, crown, and pavilion. In contrast, the AGS reports the measurements without rounding off.

It's also worth mentioning that the AGS is the only laboratory that uses ASET to measure diamond light performance. The AGS Diamond Quality Document (DQD) shown above provides the ASET 30 and ASET 40 scans. In that case, you can judge the light performance of Black by Brian Gavin Diamonds online.

Compare Diamonds From Multiple Sites:

Diamonds can look dramatically different even though they have the same grading characteristics. For example, you will see dramatic differences between G-color and VS2 Clarity, 1-carat round diamonds depending on the proportions and degree of optical precision.

In that case, it pays to compare the images for several diamonds side-by-side and pick the one that reflects light more evenly. Look for high contrast brilliance across the arrows pattern and throughout the body of the stone.

Compare ASET and Ideal Scope images and eliminate diamonds that exhibit a moderate amount of light leakage. Also, beware of diamonds that have black obstructions under the table facet.

Once you have settled on a ring style, you can compare several diamonds of similar grades to find the one you like. Be aware that each vendor caters to a specific niche, so the diamond cut qualities and performance will be different.

For example, Brian Gavin is the King of Cut, specializing in ultra-super ideal cut diamonds. In contrast, Blue Nile and James Allen focus on a broader market and offer standard ideal-cut diamonds. Notably, James Allen True Hearts diamonds fall somewhere in the middle of the spectrum.

Establish A Budget and Stick To It:

It is easy to spend a lot on diamonds and continually adjust your budget upwards. For that reason, it's essential to set a budget before you start shopping for diamonds.

We do not adhere to conventional theories about how much you should spend on a diamond engagement ring, such as 2-3 months' salary. From our perspective, the true meaning of an engagement ring is the love that it symbolizes.

In that case, you should designate an amount that you feel comfortable spending on an engagement ring. Then, buy the most spectacular-looking diamond you can afford in that price range.

Of course, it helps to know how much high-performance diamonds cost. It's also essential to realize the degree of sparkle and light performance factors in diamond prices.

In that case, it's not reasonable to think that you can buy an ultra-super ideal cut diamond for the cost of standard GIA Excellent. Similarly, you wouldn't expect to buy a Porsche GT3 RS for the price of a standard 911 non-turbo.

Ask an Expert to Review the Details:

Suffice to say that some people in the industry know more about diamonds than others. In fact, there is a vast difference in experience between the affiliates that promote diamonds online.

Likewise, there are differences in the performance that results from various degrees of diamond cut quality. Subtle factors such as slight differences in proportions, optical precision, and inclusion type can dramatically affect the price.

In fact, the elements of cut quality can affect diamond prices by up to sixty percent. In that case, it's a good idea to have an expert review the characteristics before you buy.

It makes sense to take advantage of the insight that decades of industry experience provides, then you can make the final decision. Contact Us for personalized assistance from a diamond buying expert. You can also check out these diamond buying guides.
