The short answer

Google Maps will find the nearest gem shop. It can't tell you which one to trust. Before you buy, get four answers in writing: what the stone is (natural, synthetic or imitation), every treatment, an independent lab report on any stone that matters, and the return terms. A good shop gives all four, near home or on a trip.

What it is
Natural, synthetic or imitation, in writing
Treatment
Every treatment, in writing
Report
An independent lab, never the shop itself
Returns
Days and conditions, in writing
In your hand
Two lights, loose if possible, a 10x loupe

Gem shop, crystal shop or jeweler: which one do you need?

Not every shop on the map sells what you are after. Pick the right door first.

ShopWhat it sellsGo there to
Gem dealerLoose stones, one by oneChoose the stone itself
JewelerFinished jewelry, settings, repairsSet, resize or repair a piece
Crystal or rock shopMinerals, specimens, tumbled stonesCollect, or simply browse

The lines blur, and the sign on the door proves nothing. Whatever the shop calls itself, ask the same questions.

What should a gem shop tell you before you buy?

Four things, written on the invoice or the report. Not just said at the counter.

  1. What the stone is. Natural, synthetic or imitation. A synthetic is grown by people, with essentially the same chemistry and structure as the natural stone. An imitation only looks like it, and glass is the oldest one. Both are fine to buy, as long as they are sold under their own name.
  2. Every treatment. Almost all rubies are heated, and most emeralds are filled with oil or resin. That is normal. A shop that won't say, or doesn't know, is not. A treatment can change the value and the way you care for the stone.
  3. An independent lab report on any stone that matters to you. Independent means the lab is not the shop. If the lab offers an online lookup, check the number yourself. Here is what a gemstone certificate proves, and what it doesn't.
  4. The return terms. How many days, in what condition, refund or credit. Written down.

My rule on the third one: whoever checks a stone should never be the one selling it.

Hello, I am interested in this stone and have a few questions before I decide.

1. What exactly is this stone: natural, synthetic or imitation? Could you write it on the invoice?
2. Has the stone been treated, and how? Could you write it on the invoice?
3. Is there a report from an independent laboratory, or can the stone be sent to one before I decide?
4. What are your return terms: how many days, in what condition, and refund or credit?
5. Could I see the stone loose, by a window, before I decide? If I am choosing from afar, could you send a video of it turning under steady light?

Thank you. I will come back to you once I have your answers.

What to check with the stone in your hand

This is what a shop near you gives you that a screen can't. Use it.

  • Two lights. Look at it by a window, then under the shop lamps. Color shifts with the light: blues and greens tend to look their best under fluorescent light, reds under warm bulbs.
  • Loose if you can. A setting hides part of the stone and can change how its color looks.
  • A 10x loupe. Turn the stone and look from every angle: chips, scratches, what sits inside. A loupe won't identify the stone on its own.
  • The paper against the stone. The weight and measurements on the report should be those of the stone in front of you.

Red flags in a gem shop, and one that isn't

  • The only paper is the shop's own. A certificate printed by the seller is not an independent report.
  • Nothing goes in writing. What the stone is and how it was treated stay spoken, never printed.
  • "Real", "genuine" or "natural" on a lab-grown stone. Those words don't belong on a synthetic. "Synthetic" or "lab-grown" does.
  • A price far below every other seller. Ask why. Glass has turned up in parcels for sale, mixed in with the natural stones it imitates.
  • A mine name, and no way of knowing it. Ask how they know. What I have learned: "straight from the mine" is marketing almost every time.
  • Pressure. "Last one", "today only". A good stone survives a night of thinking.

And the one that isn't: a high price. A shop has the right to its margin. The scam is not knowing what you are buying.

Buying gemstones on a trip

My first stones came from the gem shops of Galle Fort, in Sri Lanka. I bought them like a tourist. Being close to the mines changes the scenery, not the rules.

Gem towns are trading centers. Bangkok cuts, treats and sells stones from well beyond Thailand, and Colombo is a meeting point for the trade too. So a stone bought there is not automatically from that country, or untreated. Ask the same four questions, and keep the invoice that says what you were told.

Is a gem shop near you better than buying online?

Near you, you hold the stone and see it in real light. Online, you get choice and time to compare, but no stone in your hand, and a seller you have never met. How do you trust someone you have never seen, whose story you don't know?

Online, ask for the same four answers, plus two more: a video of the stone turning under steady light, and a return window long enough to show the stone to a jeweler you trust. For sapphire, here is how to buy a sapphire online.

For the record, Joalys is not a shop you can walk into. We sell loose stones online, and every stone goes to an independent laboratory once it is yours, with the report sent alongside it. Browse the collection, or tell us the stone you are looking for.

Quick answers

Is it safe to buy gemstones online?
It can be, if you get the answers you would ask for in a shop: what the stone is, every treatment, an independent lab report on a stone that matters, and the return terms in writing. Ask for a video of the stone turning, and a return window long enough to have it checked.
How can I tell if a gemstone is real?
Often not by eye. Glass can imitate many colors, and a synthetic has essentially the same chemistry and structure as the natural stone. A loupe shows chips and inclusions, but telling natural from synthetic usually takes a laboratory. On any stone that matters, ask for an independent lab report.
Should I buy a treated gemstone?
Yes, if the treatment is disclosed and the price reflects it. Heating sapphire is common and widely accepted, because its effect is usually permanent. A fine untreated stone costs more because it is rare. Ask which treatment it is: some need special care.
Is it cheaper to buy gemstones in Sri Lanka or Bangkok?
Not by default. Being near the mines doesn't tell you what a stone is or what it is worth. Bangkok cuts, treats and sells stones from many countries, and Colombo is a trading center too. A fair price starts with knowing what you are buying, so the same four questions apply.

The short version

Let the map find the shops. Let four written answers pick one: what the stone is, every treatment, an independent report, the return terms. Then hold the stone in two lights before you decide.
