The two stores below have a perfect customer service record with our referrals for over 5 years now, with hundreds of positive testimonials.
We stopped giving info about anyone else. All we suggest is that you use these stores
as benchmarks to compare anyone else you find on your own,
and buy wherever you feel the most confident about integrity and helpfulness.

If you compare in full, you might end up seeing what we see — there are a LOT of stores that offer most of the criteria we tested for, but only two that offer it all.
That was frustrating for us, but I have found that it saves me time and lets me sleep at night knowing that I am always sending you
to a place that will treat you right. So there you have it. My process in a nutshell. Compare for yourself and let me know how it goes.

HOT TIP! Start your quest for a diamond by selecting your personal diamond dealer
as priority one — because a good dealer will be the best source
for guidance at every step. You will have the best experience
if you stay with one or two dealers from beginning to end. As
you refine your parameters, your personal dealer will learn to
understand your needs and often will do a custom search of the
market, if needed, to find just the right gem for your budgetand tastes.
