Selling a diamond is not something most people do often. Whether you have a loose diamond, an engagement ring, inherited jewelry, or a piece you no longer wear, the most important thing is understanding what you have before making a decision.
At Diamond Source Jewelers, I provide private diamond evaluations in Denver and Greenwood Village with honesty, clarity, and no pressure. My goal is to help you understand the quality, condition, and market value of your diamond so you can make an informed choice – whether you decide to sell, redesign, keep, or simply learn more about the piece.
At our Greenwood Village location, every client works directly with Bruce Chase – founder of Diamond Source Jewelers, Graduate Gemologist, Certified Appraiser, and an experienced jeweler with more than 45 years in the industry.

Start by scheduling a private consultation and bringing in the diamond, ring, or jewelry piece you would like evaluated. If you have a grading report, receipt, appraisal, or previous documentation, bring it with you – but it is not required.
Bruce will review the diamond’s quality, condition, certification, shape, carat weight, and current market demand. After the evaluation, you will receive a clear explanation and a fair offer with no obligation to sell.
If you decide to accept the offer, the process can usually be completed quickly and professionally. You will know exactly what to expect before moving forward, with no pressure and no surprises.
At our Denver and Greenwood Village office, we evaluate and purchase many types of diamond jewelry.
Whether you are selling an inherited piece, a previous engagement ring, a loose diamond, or diamond jewelry you no longer wear, Bruce will review each item carefully and explain its value based on quality, condition, and current market demand.
Custom diamond jewelry can carry both material value and craftsmanship value. We evaluate each piece individually, including the diamonds, setting, metal, design quality, condition, and overall resale potential.
If you are looking to sell a loose diamond, Bruce can evaluate the stone based on cut, color, clarity, carat weight, shape, certification, condition, and current demand. A grading report can be helpful, but it is not always required.
Vintage diamond jewelry often requires a more careful review. Age, design period, craftsmanship, condition, diamond quality, and market desirability can all influence value. Bruce will help you understand what makes the piece meaningful and what may affect its selling price.
Designer diamond jewelry may carry added value depending on the brand, authenticity, condition, materials, and market demand. We review each piece carefully and explain how the designer name, diamonds, and craftsmanship may affect the offer.
Diamond wedding bands, eternity bands, anniversary bands, and custom bands are evaluated based on diamond quality, metal type, craftsmanship, condition, and resale potential. Whether the band is classic or custom-made, we will help you understand its value clearly.
We buy diamond engagement rings in many shapes and styles, including solitaire, halo, three-stone, vintage, and custom designs. Bruce will evaluate the center diamond, side stones, setting, metal, condition, and documentation before explaining the offer.
Bring any documents you have, including grading reports, appraisals, receipts, certificates, or original purchase details. These documents can help support the evaluation, but they are not required to receive professional guidance.
A diamond’s resale value is different from its original retail price or insurance replacement value. Factors such as diamond quality, certification, condition, shape, setting, market demand, and whether the diamond is mined or lab-grown can all affect the offer.
Selling a diamond can be emotional, especially if the piece was inherited or connected to a personal chapter in your life. Bruce approaches every evaluation with respect, discretion, and honesty so you can make a clear decision at your own pace.

















Graduate Gemologist & Certified Appraiser
Before you sell a diamond, it is important to understand what affects its value. Size matters, but it is only one part of the evaluation. Cut, color, clarity, carat weight, shape, certification, condition, setting, and current demand all play a role.
At Diamond Source Jewelers, Bruce takes the time to explain these details clearly so you are not left guessing. Whether you choose to sell or simply want to understand your diamond better, the consultation is designed to give you honest answers and confidence.
You can bring in loose diamonds, diamond engagement rings, diamond wedding bands, inherited diamonds, estate diamond jewelry, custom diamond jewelry, designer diamond jewelry, and many types of fine jewelry with diamonds.
Each piece is evaluated based on its quality, condition, documentation, and market demand.
A diamond certificate or grading report can be helpful, but it is not required. If you have documentation from GIA, IGI, AGS, EGL, or another lab, bring it with you.
If not, Bruce can still evaluate the diamond and explain the important details.
Your diamond is evaluated based on cut, color, clarity, carat weight, shape, condition, certification, whether it is mined or lab-grown, and current resale demand. If the diamond is set in jewelry, the metal, setting, craftsmanship, and additional stones may also be reviewed.
No. The evaluation is designed to help you understand your diamond and your options. You are never pressured to sell. Bruce will explain the value, the reasoning behind the offer, and any other options that may make sense.
If you decide to accept the offer, the process can usually be completed quickly. Bruce will explain the next steps clearly during your consultation so you know exactly what to expect before making a final decision.
