• Sapphires — color zoning, diffusion treatments and quality factors.

• Spinel — natural versus synthetic stones and identification clues.

• Paraíba Tourmaline — copper-bearing tourmaline, apatite look-alikes and origin-related value.

INSIDE EVERY GUIDE

2. UNDERSTAND THE DEAL

Explore sourcing options, pricing factors and side-by-side deal examples. Learn to account for selling fees, buyer safety and resale risks, then follow a 30-day starter plan.

MADE FOR

Jewelry lovers, collectors, estate-sale and pawn-shop hunters, and beginners exploring gemstone resale.

No gemology background required. Clear explanations. Practical comparisons. Six gems in one collection.

Build your knowledge before you buy. Know the questions to ask before you sell.

Educational content. Visual checks and home tests cannot confirm every stone's identity, treatment or origin; professional laboratory testing may be needed. Resale involves risk, and profits are not guaranteed.
