Diamond Buying Checklist

Use this 10-step checklist before making any online diamond purchase. Complete each step in order to ensure you are buying safely and getting the best value.

Before You Shop

1
Set your total budget

Decide the maximum you will spend on diamond + setting combined. Write it down. Do not exceed it regardless of what you see while shopping. Include tax and any shipping costs in your budget calculation.

2
Choose your diamond shape

Round is the most expensive. Oval, cushion, and pear offer 15–30% savings with larger visual appearance. Choose based on your partner's preference, not what is cheapest.

3
Decide: natural or lab-grown

Lab-grown = 60–80% savings, same physical properties. Natural = geological rarity, slightly better resale. This is a personal/philosophical choice. Read our comparison guide.

4
Set your minimum specifications

Cut: Excellent only. Color: G–H for white gold, I–J for yellow gold. Clarity: VS2–SI1 for brilliant cuts, VS1 for step cuts. Never compromise cut to get a larger stone.

Verify the Retailer

5
Check the retailer's credentials

Physical address (not just PO box)? Real phone number? Google reviews? How many years in business? BBB or Jewelers Board of Trade member? If any of these are missing, proceed with caution.

6
Confirm GIA or IGI certification

The diamond must have a GIA or IGI grading report. Not EGL. Not GSI. Not "in-house appraised." The report number must be displayed on the listing before purchase.

7
Verify the certificate independently

Go to gia.edu/report-check or igi.org. Enter the report number. Confirm every spec matches the listing. If anything is off, do not buy.

Before You Pay

8
Compare total cost across 2–3 retailers

Diamond + setting + shipping + tax = total. Compare total out-the-door cost, not just the diamond price. Factor in any restocking fees or return shipping costs.

9
Pay with a credit card

Credit cards offer purchase protection and chargeback rights. Never pay by wire transfer, cryptocurrency, gift cards, or Zelle. Debit cards offer less protection than credit cards.

10
Confirm shipping and return terms

Fully insured shipping? Signature required? 30+ day return window? Full refund (not store credit)? Who pays return shipping? Get clear answers to all of these before completing the purchase.

After you receive the diamond: Inspect it under good lighting. Have it checked by an independent jeweler if you want extra assurance. Verify the laser inscription matches the report number. If anything does not match or you are not satisfied, return within the policy window.
