Are you looking to sell gemstones and want to ensure you receive their true value? Whether you’ve inherited precious stones, are upgrading your jewelry collection, or simply need to liquidate some assets, knowing how to navigate the gemstone market is essential. At Diamond Source Jewelers, we pride ourselves on offering fair, transparent valuations from certified gemological experts. This comprehensive guide will walk you through everything you need to know about selling your gemstones for maximum value.
Understanding the Gemstone Market: What Your Stones Are Really Worth
The gemstone market operates differently from other commodities. Unlike gold, which has a daily spot price, gemstones are valued based on multiple factors that require professional expertise to assess accurately. Many sellers are surprised to learn that their stones may be worth significantly more—or occasionally less—than they anticipated.
At Diamond Source Jewelers, our founder Bruce Chase brings over 40 years of experience as a GIA Graduate Gemologist to every evaluation. This expertise ensures you receive an accurate assessment based on current market conditions and professional standards, not just a quick estimate.
The value of your gemstones depends on various characteristics that trained gemologists analyze using specialized equipment and knowledge. Understanding these factors can help you have realistic expectations and make informed decisions when selling your precious stones.
The 4Cs of Gemstone Valuation
Similar to diamonds, colored gemstones are evaluated using specific criteria that determine their market value:
Color – The most important factor for colored gemstones. Ideal colors vary by stone type, but generally, vivid, saturated hues without being too dark or too light command premium prices. For example, the most valuable rubies display a pure, vibrant red with a hint of blue, often described as “pigeon blood” red.
Clarity – This refers to the absence of inclusions or flaws within the stone. Different gemstone varieties have different clarity expectations—emeralds typically have inclusions, while aquamarines are expected to be relatively clear.
Cut – A well-cut gemstone displays proper proportions and symmetry that maximize the stone’s color and brilliance. Expert cutting can significantly increase a gemstone’s value by enhancing its natural beauty.
Carat – The weight measurement for gemstones. Larger stones of high quality are rarer and therefore more valuable, often increasing in price exponentially with size.
Beyond the 4Cs: What Makes Your Gemstone Special
Several additional factors can significantly impact the value of your gemstones beyond the basic 4Cs:
Geographic origin can dramatically affect value, particularly for rubies, sapphires, and emeralds. For instance, Kashmir sapphires command extraordinary premiums due to their rarity and distinctive visual characteristics. Similarly, Burmese (Myanmar) rubies and Colombian emeralds are highly prized for their superior quality and historical significance.
Treatment status is another crucial consideration. Untreated natural gemstones that achieve desirable color and clarity without enhancement are increasingly rare and valuable in today’s market. Common treatments include heat treatment for sapphires, oiling for emeralds, or fracture-filling for various stones.
Rarity factors heavily into valuation—certain colors or varieties that are no longer actively mined, such as Paraíba tourmalines from Brazil or fine natural alexandrites, can command exceptional prices due to their limited availability.
Historical significance or provenance can add substantial value to otherwise ordinary stones. Gemstones with documented ownership by celebrities or historical figures, or those from famous jewelry houses like Tiffany or Cartier, often sell for premiums well beyond their intrinsic gemological value.
Sell Your Gemstones Locally vs. Online: Pros and Cons
When deciding where to sell your gemstones, you have several options, each with distinct advantages and drawbacks. Making an informed choice between local and online selling channels can significantly impact both your experience and the final amount you receive.
| Selling Option | Advantages | Disadvantages |
|---|---|---|
| Local Jeweler (like Diamond Source) | Face-to-face evaluation, immediate payment, no shipping risks, personalized service, relationship-building | May need to visit multiple jewelers to compare offers |
| Online Marketplaces | Potential for wider audience, possibility of higher offers | Fees (typically 10-15%), shipping risks, delayed payment, scam potential, requires photography skills |
| Auction Houses | Good for rare/high-value pieces, professional marketing | High commissions (15-25%), lengthy process (3-6 months), unpredictable results, minimum value requirements |
| Consignment Shops | No upfront cost, professional display | Slow process, high commissions, no guarantee of sale |
Local Gemstone Buyers: Building Trust Face-to-Face
Selling to a local gemstone buyer like Diamond Source Jewelers offers significant advantages, particularly for sellers who value security and immediacy. When you work with a local gemologist, you witness the evaluation process firsthand, gaining insights into your gemstones’ characteristics and value determinants. This transparency builds confidence in the fairness of the offer.
The personal relationship aspect shouldn’t be underestimated. Working with Bruce Chase means connecting with a professional who has built his reputation in the Denver community for over four decades. This established presence ensures accountability and reliability that anonymous online transactions simply cannot provide.
Local sales also eliminate shipping concerns entirely. The risk of loss, damage, or theft during transit—a significant worry when shipping valuable gemstones—becomes a non-issue. Additionally, you’ll receive immediate payment once you accept an offer, without the delays associated with online marketplace transactions or auction settlements.
Online Gemstone Marketplaces: Navigating the Digital Options
Online platforms offer the allure of a potentially broader market, but come with significant considerations. Popular options include specialized gemstone marketplaces like GemRockAuctions or Ruby Lane, general auction sites like eBay, and dedicated jewelry resale platforms like Worthy.
These digital channels may occasionally yield higher prices for certain stones, particularly rare specimens with international collector appeal. However, this potential advantage comes with substantial costs and risks. Most platforms charge seller fees ranging from 10-15% of the final sale price, substantially reducing your net proceeds.
The online selling process requires considerable effort. You’ll need to take professional-quality photographs, write detailed descriptions, manage potential buyer questions, handle secure shipping, and often wait weeks or months for payment. Additionally, without face-to-face interaction, you’re more vulnerable to various scams that plague online marketplaces.
Perhaps most importantly, online platforms typically attract buyers seeking discounts. Many expect prices significantly below retail value, which can undermine your ability to receive fair market value for high-quality stones.

Preparing Your Gemstones for Evaluation
To ensure the most accurate valuation of your gemstones, consider these preparation steps before your appointment:
Gather any existing documentation you may have, including previous appraisals, certificates from gemological laboratories (GIA, AGL, etc.), or receipts showing purchase history. While not required, these documents can provide valuable context and sometimes support higher valuations.
Clean your gemstones gently with a soft cloth and mild soap solution if they’re visibly dirty. However, avoid aggressive cleaning methods that might damage delicate stones. If you’re uncertain about safe cleaning procedures, it’s better to bring them as-is—we have professional equipment to properly clean stones before evaluation.
Organize your stones logically if you’re bringing multiple items. Separating them by type (diamonds, colored gemstones, mounted jewelry pieces) helps streamline the evaluation process.
What to Expect During Your Gemstone Appraisal
During your appraisal appointment, Bruce will use several specialized tools to assess your gemstones accurately. The process typically begins with careful visual examination using a jeweler’s loupe or microscope to identify the stone type and evaluate clarity characteristics.
For identification confirmation, we employ refractometers that measure how light passes through the stone—a fundamental property unique to each gemstone variety. Spectroscopes may be used to analyze the absorption spectrum, particularly helpful for distinguishing natural from synthetic stones or detecting treatments.
Specific gravity testing might be conducted for unusual specimens, providing another diagnostic property to confirm identification. For diamonds, we use diamond testing equipment to verify authenticity and distinguish them from simulants.
Throughout this process, Bruce explains his findings in plain language, answering any questions you might have about the evaluation methods or results. This transparency is central to our approach and helps you understand exactly how we arrive at our valuation.
Types of Gemstones We Buy: From Precious to Semi-Precious
At Diamond Source Jewelers, we purchase a wide range of gemstone varieties. While we specialize in high-quality precious stones, we evaluate all gemstones on their individual merits:
Diamonds: All sizes, cuts, and qualities—from estate pieces to modern cuts, loose or mounted. We have particular interest in diamonds over 0.50 carats with good color and clarity.
Rubies: Natural rubies from all sources, with special interest in unheated Burmese (Myanmar) specimens, which command significant premiums in today’s market.
Sapphires: All colors including blue, pink, yellow, padparadscha, and colorless varieties. We particularly value fine blue sapphires from Kashmir, Burma, and Ceylon (Sri Lanka).
Emeralds: Colombian emeralds are especially sought-after, though we purchase quality specimens from all locations, including Zambia and Brazil.
Semi-Precious Stones: Quality examples of tanzanite, aquamarine, tourmaline, spinel, garnet, opal, and many other varieties. Fine specimens of these stones can be surprisingly valuable.
Rare Collector Stones: Alexandrite, Paraíba tourmaline, demantoid garnet, fine imperial topaz, and other rare varieties are of special interest to us and often command exceptional prices.
We evaluate mounted and loose stones, modern and antique cuts, and certified or uncertified gemstones. Our expertise allows us to recognize value even in unusual or overlooked specimens.
Frequently Asked Questions About Selling Gemstones
Q: How do you determine what my gemstones are worth?
A: We assess each stone based on the 4Cs (color, clarity, cut, and carat weight), plus additional factors like origin, treatment status, and market demand. Our valuations reflect current wholesale market conditions, allowing us to make competitive offers while still operating as a sustainable business.
Q: Do I need certification (like GIA) to sell my gemstones?
A: While certificates can be helpful, they’re not required. Our in-house gemological expertise allows us to evaluate uncertified stones accurately. For exceptionally valuable pieces, we may recommend obtaining certification before selling if it’s likely to significantly increase value.
Q: What if I inherited gemstones and have no idea what they are?
A: This is a common situation, and exactly where our expertise proves valuable. We can identify unknown stones, separate valuable gems from simulants or glass, and provide a clear explanation of what you have. Many clients are pleasantly surprised to learn their inherited pieces are worth significantly more than expected.
Q: Are lab-created (synthetic) gemstones worth anything?
A: Lab-created gemstones do have value, though typically less than their natural counterparts. Older synthetic stones, particularly those in vintage jewelry pieces, may have collectible value. We evaluate synthetic stones on a case-by-case basis.
Q: How long does the evaluation process take?
A: Most appraisals take 30-60 minutes, depending on the number and complexity of items. We prioritize thoroughness over speed to ensure accurate valuations.
