Need help finding the perfect diamond?

Frequently asked questions

Why should I use this technology to find a diamond?

There are many factors that contribute to the price of a diamond. Some are well known (think carat size, diamond color etc.) and others are more mysterious. We believe there is no reason for this mystery. Using our technology will allow you to shine a light on these dark factors and obtain a high level of comfort with the price you are paying for your diamond

Do I have to pay StoneAlgo anything?

No. We offer our platform as a completely free service to you.

Why did you come up with this idea?

We do have a background in using data to find value in markets. But the tipping point was when one of us got engaged and had to begin searching for value in a market that was not as transparent as those we were used to dealing in. We developed an algorithm to help find the perfect diamond and the rest is history.

How exactly does StoneAlgo work?

All the power of the Machine Learning algorithm we created is there waiting for you to tap into. Use our intuitive walkthrough process to begin your search using a few of your preferences and let our propietary Stone Score and Cut Score steer you toward a beautiful diamond with great value.

Once you find a diamond you like you can either favorite the diamond for review later (if you're signed up!) or you can click the indicated links to go to the retailer's site and start the process to purchase the diamond. Any saved diamonds will show up in your personal data page as well as other useful statistics regarding your search history.

What is Machine Learning?

Machine Learning is designed to optimize problems which are not obvious or not solvable by human deduction alone (or we can't do it fast enough to make it worth the effort).

Can I trust your machine learning algorithms to show me the diamonds with the best value?

StoneAlgo prioritizes the integrity of our data and the values the algorithm outputs over any other factor when recommending diamonds to you on our platform. The Cut Score and Price Score metrics are the drivers behind the diamonds you will see. We have spent an incredible amount of our time working on the algorithm and ensuring the output is something you can trust and therefore use as a tool when comparing diamonds.

Will I buy the diamond from StoneAlgo?

No. We will put our algorithm to work for you to find the perfect diamond with the best value within your budget. Once you find the perfect diamond you can click any of the indicated links to the retailer's website where you will finalize the purchase.

In certain cases, StoneAlgo will earn a fee from the online diamond dealer for having referred you to their site.

Who are the retailers that I will eventually buy from?

We have a more detailed answer to this question on our retailers page. But in general these are online diamond dealers that we've vetted to maintain excellent reviews on Google, Yelp, WeddingWire etc. as well as uphold certain standards in business in general reflected by their Better Business Bureau rating.
