We appreciate that jewelry is incredibly personal, and whether you ultimately choose a natural or lab-grown diamond depends on your priorities. Because they are synthetically grown in a matter of weeks, lab diamonds are often much less expensive than natural diamonds – meaning you can often get a larger stone at a lower price. But, it’s because of this that lab-grown diamonds also lack long-term value – and why they are not part of our offering.

If purchasing a precious stone that maintains value in the long run is important to you, then you’ll find a beautiful selection of high quality diamonds, priced fairly, at Long’s.

What is the difference between natural and lab-grown diamonds?

Service 1

Naturally Rare

Whereas natural diamonds are formed under the earth’s surface over millions of years, lab-grown stones are mass produced and available in abundance.

Service 2

Heirloom Quality

Scarcity and geological history give natural diamonds their symbolic value and enduring appeal. It’s why many view them as generational heirlooms.

Service 3

Long-Term Value

Because they are abundantly available, lab-grown diamonds have little to no resale or trade-in potential. Until they are considered a sound investment, we can’t in good conscience stand behind them!

What Our Customers Are Saying

I’m very happy with my purchase. I really like the feature on your site that lets me try rings on virtually; it was really helpful. I would definitely shop with Long’s again.

- Alex. A

When the ring arrived, it was actually BETTER than the picture. I will definitely buy from them again.

- Greg J.

There is a wide selection, and the prices are really affordable for classic, one-of-a-kind pieces.

- Marie R.

This is the second time we have bought online from Long's. They carry more quality vintage or previously owned items that you can't find elsewhere. I especially like knowing that I am buying from a reputable dealer. And their shipping is very fast and very well packed.

- Kim S.

Not only is the quality of the jewelry excellent, but the helpfulness and knowledge of the staff is superb.
