How much is my diamond worth?

The value of a diamond is primarily determined by:

CARAT: The weight of the diamond

COLOR: A wide ranging scale of colors affect prices

CLARITY: The clearer the diamond the more expensive it is

SHAPE: Round diamonds are more valuable than fancy shapes

CUT: How well your diamond reflects light and sparkles

To determine how much your diamond is worth we need to see the diamond and expertly determine all of these factors. Our certified gemologist has over 40 years of valuation experience and is a nationally-recognized expert.

What diamonds do you buy?

We will buy any diamonds, no matter the size, shape, color or clarity.

Do You Sell Diamond Engagement Rings?

Let us help you design the perfect engagement ring.

Do you charge for market valuation appraisals?

No, our goal is to educate our customers on what they have, what it is worth, and how to maximize the value.

What is the difference between a fair market value appraisal and an insurance appraisal?

Fair market value appraisal is defined as the agreed upon price by a willing buyer and a willing seller. An insurance appraisal is a formal appraisal document required by insurance companies in order to insure an item at the current retail replacement value, this is usually double the fair market value.

What Our Clients Are Saying

Whether buying a gift or selling unused jewelry, I cannot recommend Paradigm Experts more highly. Not only do you receive personal service and attention from expert jewelers, but you can save thousands of dollars off retail prices. If you are in the market for diamonds or an engagement/wedding ring, Paradigm Experts is your best choice by far.

I am a real estate agent and have worked with Steve professionally for many years. Many of my clients are downsizing and I have referred them to Steve when they have had jewelry, silver, and coins to sell. Every one of them has enjoyed the experience and been happy with the prices offered. There is never any pressure to sell and it is obvious Steve knows his business! I have personally sold some of my own valuables and referred family and friends as well. I highly recommend Paradigm Experts!

Your Appraisal Roadshow at our St. Mark’s 3rd Agers gathering last Saturday was an overwhelming success! I wish that we could have somehow recorded all the positive and enthusiastic comments we’ve had from many people! In addition to the knowledgeable appraisals of our treasures, the related stories you elicited were a delight to hear! We thank each of you very much!
