Built for the side without a counter.

People sell diamonds for divorce, inheritance, hardship, or upgrade. The buyers — pawn shops, mall jewelers, online buyers — see hundreds of stones a week and know exactly what each one is worth. The seller has typically never sold a diamond before, doesn't have a current appraisal, and walks into the negotiation 80% behind on information.

That information gap is worth somewhere between 20% and 50% of the stone's value. We built this site to close it.

• Diamond Value Calculator — enter the 4 Cs from your GIA report (or guess), get four prices: retail, private resale, jeweler buy-back, pawn. Our model is built from public price lists (Rapaport-style heuristics) refined with current market spread data.
• Selling guides — engagement rings, divorce rings, inherited jewelry, lab-grown vs natural. Honest math on each scenario.
• The 4 Cs explained — without the marketing fog. Which C actually moves the price and where you can compromise.
• Jeweler directory — vetted local buyers in 24+ US metros (rolling out).
• Matching service — submit your diamond, we forward to 1–3 vetted local jewelers. No commitment, no commission, no public listing.

The calculator uses a model trained on public Rapaport per-carat price lists, adjusted for shape, cut grade, and condition (loose / set / antique). Resale and offer bands come from publicly available data on jeweler buyback spreads (typically 20–40% of retail) and pawn shop spreads (typically 10–25%).

The model is heuristic, not appraisal-grade. We're explicit about confidence levels — anyone selling a stone over $5,000 should always get at least two written offers from GIA-certified jewelers before deciding.
