Most respected and trusted diamond buyers have affiliations with major industry bodies and associations. Associations help regulate the market and the activities of their members. Applying for affiliations includes hand over details of their company and ensures they have fixed premises from which they operate. WP Diamonds is a trusted member of the The Jewelers Board of Trade, the Jewelers Vigilance Committee, and the National Pawnbrokers Association.

Most large trusted buyers have access to significant capital and the right resources to fund the diamond purchases it makes.

White Pine can complete transactions of all sizes, transferring money the same day.

How To Choose The Right Diamond Buyers?

Where you sell your diamonds and diamond jewelry is important. You want to sell to a trustworthy buyer who takes your privacy seriously. Here we list some advice.

  1.  A Track Record In Business – Its important that you examine the trading history of a potential buyer. You can tell a lot about a company from their reviews on Google or Yelp. Also take a look at their Better Business Bureau record.
  2. Investment In Their Business  – Take a look at the amount of money that has been invested in their location, operations, website and/or storefront.  WP Diamonds has offices on 5th Avenue New York and has a first rate website with explanatory videos.
  3. Transparency And Honesty – It’s essential that the diamond buyer you choose adopts a methodical approach to diamond valuation, using fair and methodical pricing. They should also be willing to tell you why they have come up with the initial valuation that they give you. If they try and hard-sell, walk away immediately.
  4. Market Knowledge  – It’s essential that a buyer has strong connections in the market place. The second-hand diamond market for polished stones is a detailed and complex place.
  5. Security – Respected and trustworthy companies follow stringent processes in ensuring the safety and security of the customer’s diamond items. They should also follow procedures such as opening packages from customers on video and have offices which have security measures, procedures and trained staff.

5 Reasons To Choose Online Diamond Buyers Vs Local Diamond Buyers

Selling diamonds online can seem a risky and daunting experience. Here we provide 5 benefits for choosing an online diamond buyer vs a local diamond buyer.

  1. Comprehensive Buying – Local buyers know their local market and they only buy diamonds that fit that immediate local need. Online buyers have national and international reach and buy a much larger range of diamonds.
  2. Competitive Pricing – Having access to the international diamond markets present online diamond buyers with a knowledge advantage. Often this manifests itself in more competitive pricing across a larger range of stones. Online buyers tend to have smaller overheads as they don’t have an expensive premises.
  3. Convenience – Selling online is usually only just a few clicks away. You don’t have to get in your car to get a price for your items. As with other services, such as Amazon, you can get what you need quickly and simply. Our Diamond Directory contains more information.
  4. Privacy – Selling online allows you to turn your items into money without having to meet buyers face to face or broadcasting to your local community that you are selling your possessions.
  5. No Haggling – Depending on your chosen online route you will experience a premium service where there is no hard-selling and no haggling over price. This can be a very unpleasant experience in some local settings.
