Is it worth driving to a major city to sell jewelry from Castle?
If you have a piece worth $5,000+, yes — the major jewelry districts (NYC Diamond District, LA Jewelry District, Miami) consistently pay 10–25% more than non-district buyers. For pieces under $5,000, the driving and time cost typically exceeds the offer differential. The free alternative: ship to an online buyer who reaches the same wholesale market.
What proof do I need that my diamond is real?
The gold standard is a GIA or AGS diamond grading report. Without one, expect a 20–40% discount because buyers must defensively price the unknown. If you have the original retail receipt, it helps. For diamonds without papers, request a buyer evaluation in writing — reputable buyers in Castle will identify each 4C parameter (carat, color, clarity, cut) before making an offer.
How does the buyer in Castle test my gold for purity?
Three common methods: (1) Electronic gold tester — reads conductivity, accurate for 10K–24K. (2) Acid test — small scratch on a stone, drops of acid show karat. (3) X-ray fluorescence (XRF) — the most accurate, used by serious buyers. You can request to see the test performed in front of you; if the buyer refuses, that is a red flag in Oklahoma.
What is the markup on resold jewelry?
Retail jewelry markups range from 100% to 300% over wholesale. This is why a $5,000 retail engagement ring sells for $1,500–$3,000 when resold — the buyer is paying wholesale-adjacent pricing, not retail. For branded pieces (Tiffany, Cartier, Van Cleef), markups can be 4x or higher, which is why these pieces hold value better on resale.
Should I sell my engagement ring or sell the diamond separately?
Generally sell as a complete ring — the setting adds 10–20% to the offer because the buyer can resell directly without re-setting. Exception: very small (<0.3ct) diamonds in heavy settings — sometimes the gold-melt value of the setting plus a separate diamond sale beats the combined offer.
Are mail-in gold buyers in Oklahoma scams?
Some are. The reputable ones (Cash for Gold USA, Express Gold Cash, GoldFellow) operate under state licenses with publicly disclosed prices and free insured shipping. The scams use unsolicited TV ads, hide their location, and pay 30–50% below market. Always verify a precious-metal-dealer license number on the state regulator’s website before mailing.
Will my jewelry be insured during shipping from Castle?
Yes, when you ship to a licensed online buyer. Reputable buyers provide pre-paid FedEx labels with declared-value insurance up to $50,000+ at no cost to you. Tracking is real-time, signature is required on delivery, and the buyer assumes full liability from the moment they hand it to their courier. Always photograph the piece and shipping label before sending.
What is the best way to clean jewelry before selling?
Mild soap and warm water for most pieces. Never use ultrasonic cleaners on antique, opal, pearl, emerald, or turquoise pieces — these can damage the stone and reduce your offer. Never polish signed antique pieces aggressively — original patina adds value to estate buyers in Castle.
