The problem
Gemstone buying gets complicated fast
- Two similar-looking stones can have very different treatment, quality, and value.
- Photos can exaggerate color, brightness, and saturation.
- It is easy to start with the wrong stone type, size goal, or treatment expectations.
- Lab reports, seller claims, and origin statements are not all equal.
- Return policies can determine whether you are protected after purchase.
- One mistake can lead to drastically overpaying or a stone that causes problems in the future

FAQ
Common questions
Is this a formal appraisal?
No. Black Strata Gems provides educational buying guidance and sourcing help. It is not a formal appraisal, gemological laboratory report, or guarantee of identity, treatment, origin, or value.
Do I need to already have a gemstone listing?
No. The free assessment is designed to work even if you are just starting. If you already have a listing, you can include it, but it is optional.
Do you help with finished jewelry?
Yes, but the guidance focuses primarily on the colored gemstone, center stone, seller claims, lab/cert details, treatment language, and purchase risk. It is not a craftsmanship or setting appraisal.
What budget is private sourcing best for?
Private sourcing is usually best for buyers with gemstone budgets around $500+ and especially $2,000+, where the cost of choosing poorly is meaningful.
What gemstones do you help with?
Sapphire, ruby, diamond, emerald, garnet, spinel, tourmaline, aquamarine, zircon, opal, and most colored gemstones.
