The guide has all the tips for buying an engagement ring. 

The following short guide helps you avoid the potential pitfall many consumers of previously owned jewelry often make. We have outlined the many reasons to avoid the riskiest places that sell repurposed diamonds and likewise outline the potential advantages, should you decide to take the risk and shop at one of these venues for pre-owned jewelry. 

# 1 Your Local Pawn Shop

For an in-depth analysis of how to buy and sell secondhand jewelry at a pawn shop, please read A Diamocycle Guide to Selling or Buying Diamond Jewelry in a Pawn Shop. It is an in-depth dive into everything you need to know to buy and sell diamonds near me at a local pawn shop. 

For a quicker summary, read on: 


  • Pawnshops give loans on previously owned rings. If a  borrower defaults on the loan, the pawn shop might end up stocking a pre-owned diamond at a low price. That means you could score the deal of a lifetime on used jewelry for sale. 

  • The pawn shop format lets you buy used engagement rings at a bargain price. 

  • Pawn shops are generally less expensive than consignment jewelry near me.

  • s For consumers who love the art of the deal, you can negotiate with pawnshop owners. 

    • For example, when you buy used engagement rings at a pawn shop, you can use your negotiating skills to get an even better deal than may have been listed. 

  • As pawn shops are local establisments often located near you, they offer the convenience of being an in-person place to buy used jewelry. Similarly,  you can view the item in person before purchasing. 


  • Most pawnshops do not have the tools to test for synthetic diamonds. You might end up purchasing an artificial diamond, thinking you have bought an earth-mined natural diamond. 

    • Manufactured diamonds have significantly less value than earth mined natural diamonds.

  • You could buy a treated diamond, thinking you were purchasing unaltered used luxury jewelry. 

    • Treated diamonds include: fracture-filled, irradiated, coated, or laser drilled. 

    • Unfortunately, these diamonds are difficult for the untrained eye to identify. It is unlikely the pawnshop has the staff on hand to identify them when buying or selling these preowned jewelry items. 

  • You could buy a diamond simulant, which includes moissanite, cubic zirconia, and white sapphire. 

In Summary: 

Unless you have a professional gemologist as a friend who also has experience buying from pawnshops, we view pawn shops as a dangerous place to buy affordable diamond rings. 

# 2 Craigslist 

For a more in-depth look at buying used jewelry, please read the following Diamocycle Guide:, which even includes a section focused on limiting the risk of buying and selling jewelry near you. 

For a quick run-down on buying repurposed diamonds from Craigslist, read on:


  • Given that you are buying a preowned jewelry item on Craigslist, odds are high that you will not be paying a new retail price.

  •  By using Craigslist, you are able to search “Buy and sell diamonds near me,” which allows you to acquire your diamond easily and quickly. 


  •  The chances of potential fraudsters in this marketplace are high. Vendors are able to post an item, and then sell you a diamond simulant, or artificial diamond, having switched the item for a look-alike.

  • Most individual sellers prefer cash for their pre-owned diamond, which as a repurposed diamond buyer, presents you with the additional risk of a staged robbery, which can occur after during, or before the transaction. Remember to meet in a safe location.

  • As there are no safeguards on pricing, you might end up paying a retail price for a used diamond. 

  • With Craigslist, there are no return or exchange policies for buying used jewelry. The transaction is a final sale. 

In Summary: 

We feel that Craiglist is probably the riskiest place to buy a repurposed diamond. The chance of buying a diamond simulant is high. Similarly, the risk to your personal safety and the potential to be defrauded by professional criminals is also noticeably high. 

Unfortunately, there are no safeguards in place to protect you, the consumer. We would not recommend even an experienced jewelry buyer purchase used diamonds via Craigslist. Simply put, the risks are far too significant. 

# 3 eBay

  • eBay has pProfessional sellers who care about their reputation, and thus are more likely to provide higher-quality used and repurposed diamonds.  in this marketplace

  • Sellers have different return policies, sometimes safegauarding the consumer. 

  • BOn eBay, a buyer can use Paypal to safeguard their eBay transaction further.

  • Extensive inventory: IncredibleMassive amount of pre-owned jewelry to view online.

  • It is less likely to acquire a diamond simulant than some other marketplace as Ssellers receive feedback for their transactions, making it less likely for repurposed diamond buyers to purchase a simulant or inaccurately discribed item. 

  • Similarly, used diamond buyers are lLess likely to acquire a manufactured diamond, and more likely to find a accurelty described than natural earth mined diamond. 

  • As per the above, diamond buyers are lLess likely to receive a treated diamond when seraching for used jewelry on eBay than some of the other marketplaces listed in this article. 

  • eBay is safer than an in-person transaction, either at a pawn shop near you or Ccraigslist.  


  • There is still some risk when purchasing online via eBay with an unknown seller. 

    • Given that, We advise sticking to professional sellers who care about their reputation and have executed as many positive transactions as possible. 

    • New sellers could potentially either knowingly or unknowingly misrepresent used diamonds. 

  • There’s little quality control in terms of eBay’s endless inventory.  

    • Stick to purchasing diamonds that are graded by a professional lab grades to safeguard yourthe transaction.

  • While the risks inherent into purchasing a repurposed diamondpurchase go down when workingshopping with professional sellers, the likelihood of paying a higher price goes up. 

    • While you may find a lower price from a newer used diamond seller, we encourage you to weigh the risks inherent in buying a used diamond from a newer seller on eBay. than from a new seller or a seller with a few transactions goes up. So you’re losing the value from shopping for a preowned jewelry item. 

  • There is no clear guidance for market pricing.

    • Always cross-compare your prices to avoid so you could be paying a new price for a used jewelry item.

    • This is a traditional consumer safegaurd that simply is not available when you purcahse via eBay. 

  • RThe return policies are potentially challenging to execute should you get a fraudulent item and have to prove it on your end. 

    • We encourage you to always review and read return policies with care, and explore all potential outcomes should you recieve an item that does not align to your expectations. 

In Summary:

 eBay has thousands of listings forof pre-owned jewelry and professional sellers with vetted transactions. When you purchase from these sellers, the risk of fraud isgoes significantly lowerdown, but with this reduced risk comes the likelihood of your paying an above-market price for a previously owned jewelry piece. 

AsSo eBay does not offer any consumer or financial safegaurds for used diamonds, there are still inherent risks in shopping for a repurposed diamond in a marketplace. As you know, we always strong recommend consumers are able to verify their diamond with a 3rd party inspection, and that simply is not avilable via eBay.  the risks inherent of using rewards are not clear, and the dangers of a used marketplace without independent 3rd party inspection of your used diamond are not in place.

Their value is a fraction of the actual market value of an earth-mined natural diamond. Also, the resale venue for these items on the secondary market is thin.
