Ring Buying Guide
Everything you need to choose with confidence — find your exact ring size, see how carat weights really look on a hand, and learn what matters (and what doesn’t) before you buy.
Sizing ToolsFind Your Ring Size
Two printable guides, drawn to exact scale. Print at 100% (“Actual Size”) on US Letter paper — each includes a bank-card outline and a dual inch/millimeter ruler so you can confirm your printer didn’t rescale anything.
Printable Ring Sizer
Measure at home two ways: wrap the cut-out strip sizer around your finger, or match a ring you already own against true-size circles. Covers US sizes 3–13.5, including half sizes.

Download the Size Chart (PDF)One page · print at 100% scale- Measure at the end of the day, when fingers are largest — never when your hands are cold.
- Measure two or three times and keep the size that repeats.
- If your knuckle is the widest point, measure it too and pick a size in between.
- Wide bands (6 mm and up) fit more snugly — consider going up a half size.
- Between two sizes? Choose the larger — most Ava Lee designs come in half sizes.
- Shopping for a surprise? Borrow a ring they wear on that finger and match it to the circles on page two of the sizer.
Seven Steps to the Perfect Ring
-
Set your budget
Forget the “three months’ salary” rule — the right budget is what you’re comfortable spending. Lab-grown diamonds can stretch it 40–60% further.
-
Learn their style
Look at the jewelry they already wear: classic or modern, gold or silver tones, simple or detailed. The setting should reflect their personality.
-
Choose the diamond shape
Round brilliant is the most popular and sparkly; oval and cushion look larger face-up with a softer feel; emerald and Asscher suit art-deco taste. Learn about shapes and the 4Cs.
-
Select the setting
Solitaires are timeless, halos add sparkle and perceived size, three-stone designs add symbolism, pavé bands add brilliance. Active hands may prefer a lower-profile setting.
-
Pick your metal
Platinum, white gold, yellow gold, or rose gold — the comparison table below breaks down durability, maintenance, and look.
-
Prioritize the 4Cs wisely
Cut first — never compromise, it determines sparkle. Then carat, then color (G–J looks colorless in a setting), then clarity (VS2 or eye-clean SI1 saves money with no visible difference).
-
Get the ring size right
Use the printable sizer above, or borrow a ring they already wear. If you’re unsure, go slightly larger — sizing down is generally easier than sizing up.
Choosing Your Metal
| Property | Platinum | White Gold | Yellow Gold | Rose Gold |

| Color | Cool silvery-white | Bright white (plated) | Warm golden | Warm pink |
| Durability | Most durable | Very durable | Durable | Very durable |
| Hypoallergenic | Yes | Usually (may contain nickel) | Usually | Usually |
| Maintenance | Develops patina; polish to restore | Re-plating every 1–2 years | Low | Low |
| Best for | Maximum durability, sensitive skin | White metal at a lower price | Classic, traditional style | Romantic, distinctive style |
Budget-Maximizing Tips
- Buy just below weight milestones — a 0.90 ct stone looks nearly identical to 1.00 ct and can cost 15–20% less.
- Consider lab-grown — chemically identical to natural, typically 40–60% less, so the same budget buys a larger or finer stone.
- Match color to metal — warm yellow or rose gold settings mask the slight tint of I–K color diamonds.
- Choose eye-clean clarity — VS2 or well-chosen SI1 looks flawless to the naked eye for far less than VVS grades.
- Add a halo for presence — accent diamonds can make a 0.75 ct center read like 1.00 ct+.
- Never compromise on cut — a well-cut diamond outshines a bigger, poorly cut one every time.
Common Ring-Buying Mistakes
Overpaying for clarity you can’t see
Jumping from VS2 to VVS1 adds real cost with zero visible difference to the naked eye. Unless you’re buying a step cut (emerald or Asscher), VS2 is the sweet spot — put the savings toward cut or size.
Choosing carat over cut quality
A 1.50 ct diamond with a mediocre cut looks duller than an excellent-cut 1.25 ct — and the better-cut stone can even appear larger because it returns more light from the top.
Ignoring the setting’s impact
The same diamond reads completely differently across settings: a solitaire makes it prominent, a halo adds size and sparkle, a bezel protects it for active lifestyles. Choose for both the stone and the wearer’s daily life.
Skipping independent certification
Insist on a grading report from GIA or IGI. Certification means you know exactly what you’re paying for, and it documents the stone for insurance.
Forgetting insurance
Insure the ring as soon as you buy it — through a jewelry rider on a homeowner’s or renter’s policy, or a specialty jewelry insurer. Keep the receipt, certificate, and appraisal together.
