What jewelry does Blue Diamond Trade Post buy, sell, and trade?

Blue Diamond Trade Post buys, sells, and trades diamond rings, gold necklaces, gemstone pieces, and estate jewelry — making it the go-to spot in Kokomo and across Indiana for anyone who wants to turn jewelry they no longer wear into cash, or find a quality piece at a fair price. This service fits anyone with jewelry sitting unused in a drawer, as well as shoppers looking for a better deal than retail.

Our team brings 40 years of industry experience to every appraisal. That means you can feel confident you are being dealt with honestly by a locally and family-owned shop, not a faceless chain. When you bring in a piece, a buyer looks it over while you wait, explains what they see, and gives you a plain-language offer. There is no pressure and no hard sell. If the number does not work for you, you are free to keep your jewelry and walk out the door.

We look at a wide range of pieces, including diamond rings, gold chains, gemstone jewelry, and estate or vintage items. Not sure whether something qualifies? Bring it in and we will take a look. Blue Diamond Trade Post serves Kokomo, Indiana and customers throughout the State of Indiana, whether you want to sell, trade toward something new, or shop our in-store selection of quality pre-owned jewelry.

What affects the value of your jewelry?

Blue Diamond Trade Post doesn't post fixed prices for jewelry because every piece is different — instead, your offer is based on a few clear factors our buyers walk you through on the spot.

  • Metal type and purity (10k, 14k, 18k gold, sterling silver, platinum)
  • Current weight of precious metal content
  • Diamond or gemstone carat weight, clarity, and cut
  • Overall condition and any repairs needed
  • Brand or designer markings, if present

Bring your piece in for a free, no-obligation look — our team will explain exactly how these factors shape your offer.
