Watch Our Process In Action

Comparing Diamond Buyers

WP Diamonds is the largest direct sale option operating in the market today. There are a number of options open to sellers that all come with pro’s and con’s:

Extremely fast, good returns, expert knowledge

WP Diamonds does not buy loose diamonds under 0.5ct

Good for very high end diamonds

Results are always uncertain and the sales process takes a long time, often you cannot sell loose diamonds

You can achieve a small premium

Expect your ring to take a long time to sell, loose stones are not sold on consignment

Private sales can also achieve small premiums

Finding someone who wants your exact stone or jewelry is like finding a needle in a haystack

It’s possible you will know the reputation of local options before looking to sell

Retailers will only buy items that have an appeal to that local market, often retailers are not diamond experts

How To Choose The Best Diamond Buyers

Where you sell your diamonds and diamond jewelry is important. Our top tips for choosing a reputable diamond buyer:

  1. Online Reviews: You can gather a lot of information about a company from their online reviews on Google, TrustPilot or Yelp. Also take a look at their Better Business Bureau record.
  2. Transparency And Honesty: It’s essential that the diamond buyer you choose provides honest price quotes. They should use a methodical approach to diamond valuation, with fair and transparent pricing. If they try to hard-sell you, walk away immediately as this is a clear red flag.
  3. Market Knowledge: It’s essential that a buyer has strong connections in the marketplace. The second-hand diamond market for polished stones is a detailed and complex place.
  4. Security: Respected and trustworthy companies follow stringent processes in ensuring the safety and security of the customer’s diamond items. They should also follow strict and clear procedures. For example: opening packages on video, clear security measures, procedures and trained staff.

Online Diamond Buyers vs Local Diamond Buyers

There are 5 clear benefits for choosing an online diamond buyer vs a local diamond buyer:

 Online Diamond Buyers

  • Comprehensive Buying: Online buyers have national and international reach and buy a much larger range of diamonds.
  • Competitive Pricing: Access to the international diamond markets gives online diamond buyers with a clear advantage. Online buyers tend to have smaller overheads as they don’t have expensive premises.
  • Convenience: Selling online is usually only just a few clicks away. As with other services, such as Amazon, you can get what you need quickly and simply.
  • Privacy: Selling online allows you to turn your items into money without having to meet buyers face to face. It avoids broadcasting to your local community that you are selling your possessions.
  • No Haggling: With WP Diamonds you will experience a premium service with no hard-selling and no haggling. This can be a very unpleasant experience in some local settings.

 Local Diamond Buyers

  • Limited Buying: Local buyers know their local market and only buy diamonds that fit that immediate local need.
  • Pricing: High overhead costs translate into lower offers.
  • In Person Only: Local diamond buyers will still require in person appointments.
  • Privacy: Selling in person on a shop floor offers limited privacy.
  • Haggling: Haggling is commonplace.
