Sell Natural Diamonds in Los Angeles: Preparing Your Jewelry

To prepare natural diamonds for sale, keep the jewelry intact, match each report to its item, separate pieces you want to keep and note known condition details. Cash 4 Gold & Diamonds buys natural polished diamonds of any size and shape in Downtown Los Angeles.

Start with the items you want to sell

Place the pieces you may sell separately from anything you intend to keep. For a collection, make a short item list: a loose oval diamond, a solitaire ring, a pair of earrings or an eternity band. Use descriptions you know rather than estimated grades.

Cash 4 Gold & Diamonds buys natural, cut and polished diamonds only. Any size and any shape are welcome, whether loose or set in jewelry. We do not buy laboratory-grown diamonds, rough material or uncut crystals. Our large-diamond guide covers substantial individual stones and multi-stone jewelry.

Keep complete jewelry and matching components together

Bring matching earrings, necklace components, removed bracelet links and accessories you already have. Note missing parts. An offer for a complete design may cover more than the single stone you first intended to discuss.

Leave stones in their settings until you have discussed any proposed work. If a stone is loose or a clasp is damaged, keep the item in its own suitable container and point out the condition. Do not undertake polishing, repairs or stone removal solely to prepare for an initial conversation.

Match each document to the correct diamond

Gather grading reports, receipts and repair records. Put a copy of the relevant document with each item on your list. A box or a familiar-looking certificate is useful context, but the actual document still needs to be matched to the piece.

For a GIA report, Report Check provides a way to consult the available record. If you have no report, tell us what you know and leave uncertain details open. Ask what additional examination would be useful before paying for it.

Separate identification, quality and money

First establish what the stone is. GIA explains the specialist identification of natural and laboratory-grown diamonds. Appearance alone is not a reliable origin test.

Next, consider the stone's quality information. The 4Cs help describe diamonds, while the condition of the actual item and the details of its setting still matter. Keep an individual diamond's weight separate from the total weight in an entire bracelet or ring.

Finally, discuss a purchase amount for the item. An appraisal and a grading report have different purposes. Neither a prior insurance amount nor an advertised retail price guarantees a current offer.

Make the evaluation conversation specific

Explain whether you are considering the whole collection or selected pieces. Ask which items a proposal includes and what information remains uncertain. If further testing or alteration is suggested, discuss its purpose and arrangements before agreeing.

  • Does the offer include the mounting and all accent stones?
  • Are the report and stone matched, or is further identification needed?
  • Are any checks, costs or conditions outstanding?
  • What happens to the amount if you retain one item?
  • Which payment method and timing are agreed?

Use the same item list when comparing offers. Our offer comparison guide explains how to keep those proposals comparable.
