List of recommended loose diamond vendors

Where to Buy a Diamond Online
This page lists companies where you can buy Loose Diamonds
The following websites all offer loose diamonds for purchase directly. The prices are all good and they all have real photos of diamonds as well as certificates for you to view. They all also offer to set the diamond in a ring, which you may choose to have them do, or you might choose to have your local jeweler do it. It’s always best to ask your local jeweler first whether they offer this service.

If you would like to buy a diamond over the internet these are the places I recommend:

Black by Brian Gavin

The Black by Brian Gavin® difference

Eclipsing all other diamonds in their light performance, the diamonds in the Black by Brian Gavin® collection represent a new level of diamond selection, cutting, and presentation
A Black by Brian Gavin® is a wonder of nature mixed with the precision of storied craftsmanship.
The Gavin Effect® Cut
A breakthrough in light optimization in diamonds.
Light is everything when it comes to diamonds. The way the light catches a diamond during a pivot or a gesture. The hypnotic movement of light as it dazzles the eye—captivating the viewer and drawing them close.
Light performance is what separates Black by Brian Gavin® from other diamonds—this dazzling light performance is due to a patent pending diamond cutting technique, which is the result of years of extensive experimentation and diamond research. You can be assured a Gavin Effect® diamond meets our strictest and most exacting quality requirements.
To achieve the strictest and most exacting light performance requirements for the Gavin Effect® cut in every diamond in the Black by Brian Gavin® collection, Brian Gavin Diamonds select the finest possible natural diamond material. They then follow a meticulous and proprietary process to optimize secondary angles, symmetry, and reflective potential. They then inspect each diamond to ensure that it meets the pinnacle of their demanding light performance standards for the Gavin Effect®.

The result is a diamond that has Impeccable Performance®, Exacting PrecisionTM and Incomparable BeautyTM. And you’re guaranteed to find it with Black by Brian Gavin®.

Ritani have a unique offer which makes their service exceptionally good: Create your ring and preview it for free.

Other online retailers require you to buy your ring before you can hold it in your hand. Add a loose diamond, ring, or designer collection item to your cart and choose “Free In-Store Preview.” Ritani handcrafts your item and appraises its value before shipment. Visit your jeweler to see your item in person for FREE. Buy today or walk away — the hold is released with no obligation. If you don’t buy the ring you preview, Ritani will melt the metal down and return the diamond to their inventory.
