David Geller: How To Make $52,000 a Year On Lost and Loose Stones




When you size a ring, it takes about 20 minutes and you charge for this service, right? (Typically about $39.) If you do another 20 minutes of work on it, shouldn’t you get another $39? Yes indeed. So what would that other 20 minutes of work be?

Stone tightening! Many jewelers already do it, although usually for free. But anytime your jeweler touches the ring, you should get paid. After all, the customer says that if you touch her jewelry and something happens, it’s your fault.

Let’s explain how we do it according to the Geller Blue Book. If we take in a ring or any jewelry for sizing or repair and it has four or fewer stones we tighten and guarantee stone tightness or loss at no charge.

But if the ring has 5-20 stones we would charge according to our prices: $39 to size the ring plus $25 to check and tighten the stones even if they aren’t loose.

My car insurance company has charged me $900 a year for the last five years and I haven’t had a single accident. The only thing I’ve cost them is 49 cents to mail me a bill. Why charge me $900 when I didn’t cost them anything? To pay for all the crazy people who do crash cars.

When I do have a wreck they never have to say “must have been your fault, we won’t pay.” They pay with a smile.


You should do the same.

Here’s how to present the charge:

“Mrs. Jones, it’s only $64 to size your ring smaller. This includes our jeweler sizing your ring to fit and you’ll not notice where the work has been done. In addition, she will check all of the stones for tightness. If any stones are loose we will make sure they are as snug as a bug when you pick it up. In addition, if during the next year the diamonds become loose we’ll tighten them at no charge and if you lose any we’ll replace them for you at no charge and with a smile. Further, our jeweler will make your ring shine like the day your husband gave it to you. We can have it back to you on Friday.”

I combined the price of $39 to size and $25 to check and tighten to make the money sound seamless.

Would you do this? Well, you’re likely doing already. Get paid for it. How much? Let’s calculate.

If you take in 50 repair jobs a week, that’s 2,600 jobs a year.


Of those 2,600 jobs, about 40-80 percent will have five or more stones in them.

That’s 1,040 to 2,080 jobs you could tell the customer that it’s $25 more to check and tighten. You’d charge this in addition to sizing for bails on pendants, new shanks, earrings repair, bracelets, etc. Some people may balk at the price and you can remove the $25 and not guarantee stone loss at all. Specify that on the envelope.

But typically 70 percent of women will gladly pay to have the peace of mind that “you’ll be responsible for.”

Seventy percent means between 728 to 2,080 people will gladly pay an extra $25 to have the items checked, tightened, and guaranteed. If you multiply those two numbers by $25 you’ll see that you’ll take in between $18,125 to a $52,000 a year for what you’re already doing!

How much do you spend a year giving away money on lost stones from your repair work? I’m told the average is between $3,000 and $5,000. I just gave you $18,125 to $52,000. Quit giving customers such a hard time whose fault it is. Do like my car insurance company. Guarantee it, take the money and treat them like a mensch.

Time for More “Me Time”? Time to Call Wilkerson

Rick White, owner of White’s & Co. Jewelry in Rogers, Ark., knew it was time to retire. Since the age of 18, jewelry had been his life. Now it was time to get that “me time” every retailer dreams about. So, he chose Wilkerson to manage his going-out-of-business sale. White says he’d done plenty of sales on his own, but this was different. “Wilkerson has been a very, very good experience. I’ve had the best salespeople in the history of jewelry,” he says. “I recommend Wilkerson because they are really the icon of the jewelry business and going-out-of-business sales. They’ve been doing it for decades. I just think they’re the best.”
