How to buy real pearls
with confidence.
Four generations of Hyderabad's pearl experts, distilled into one honest guide. Everything you need to know before you buy — types, grading, length, certification.
A well-chosen pearl necklace outlives its owner. But walk into any jewellery market in India and you'll find "pearls" ranging from ₹200 to ₹20,00,000 — all looking similar to the untrained eye. The difference between a treasured heirloom and a disappointing purchase comes down to a handful of decisions you make before you buy.
This guide is the same advice we give customers who walk into our Hyderabad showroom. It covers everything — the real science behind pearl quality, the honest differences between pearl types, and the specific questions that separate serious jewellers from sellers who hope you don't know the difference.

Real vs fake: the 5 tests that never lie
Synthetic pearls (often plastic or glass coated with pearl essence) can fool the eye but never all five senses. Here's what to test before you pay.
The tooth test
Gently rub the pearl along the edge of your front teeth. A real pearl feels slightly gritty or sandy — that's the crystalline nacre. Fake pearls feel perfectly smooth, like plastic. This is the single most reliable test.
The weight test
Real pearls feel noticeably heavier than plastic imitations of the same size. Glass fakes are closer in weight but still usually lighter. If a pearl feels suspiciously light, it's plastic.
The surface test
Under bright light, examine the surface closely. Real pearls have tiny imperfections — slight ridges, minor bumps, subtle colour variation between neighbouring pearls. If every pearl in a strand looks identical, it's synthetic.
The temperature test
Real pearls feel cool against the skin for the first few seconds, then warm to body temperature. Plastic pearls feel room-temperature immediately. A good test when you're trying on a necklace.
The drill hole test
Inspect the drill holes on a strand. Real pearl drill holes are clean and small. Fake pearl drill holes often show the inner core (glass or plastic) or have paint flaking around the edges. This is especially visible on cheap imitations.
The 5 factors that determine pearl quality
Two pearls can be the same type, same size, and same origin — yet differ in price by 10x. Here's what pearl graders actually look at.
Lustre
The most important factor
Lustre is the deep, mirror-like glow from within the pearl — caused by light reflecting through layers of nacre. Hold the pearl 30 cm from your eye in natural light. You should see your reflection on the surface and a soft glow from deeper inside. Cheap pearls look chalky or matte. Exceptional pearls look almost wet, with visible depth.
Surface
Fewer flaws = higher grade
All real pearls have some surface imperfections — bumps, spots, or tiny ridges. Grade is determined by how many, and how visible at arm's length. AAA grade: clean or very minor marks. AA: minor visible marks on 25% or less. A: visible marks on more than 25%. For necklaces where pearls face forward, even lower grades look excellent if imperfections are hidden near the drill holes.
Shape
Round is classic, baroque is artistic
Round pearls are rarest and most expensive — fewer than 5% of all cultured pearls are truly round. Near-round pearls look round from arm's length and cost 40–60% less. Oval, button, drop, baroque shapes are progressively more affordable and often more interesting in contemporary designs. Don't assume round is always better — a matched baroque strand can be more striking than a round one.
Size
Measured in millimetres
Pearl prices rise exponentially with size. A 10 mm round freshwater pearl can cost 10x a 7 mm of the same grade — because big oysters that grow big pearls are rare. For daily-wear necklaces, 6–8 mm is ideal. For bridal showstoppers, 10–14 mm South Sea pearls are the standard. Always ask the seller for exact mm measurements, not vague descriptions.
Matching
For necklaces and earrings
On a strand, every pearl should match its neighbours in colour, shape, size, and lustre — or be deliberately graduated (smaller near the clasp, larger at the centre). Mismatched strands, where pearls visibly differ in tone or shape, signal lower effort in sorting. For earrings, matching is critical — the two pearls should look like siblings.
The pearl necklace length guide
Necklace length is named, measured, and styled differently. Here's where each length sits and what to wear it with.
Collar
Sits high on the neck, often multi-stranded. Dramatic, traditional. Best with off-shoulder blouses, V-necks, and saree drapes that expose the collarbone.
Choker
Rests at the base of the neck. Versatile — works with everything from kurtis to formal gowns. Most popular length for Indian women.
Princess
Falls just below the collarbone — the "default" necklace length. Pairs with most necklines and is the classic length for a single-strand pearl necklace.
Matinee
Sits on the upper chest. Elegant for sarees, blouses, and office wear. Ideal length for featuring a central pendant or multi-strand rani haar.
Opera
Falls below the bust. Long, dramatic — can be worn single or doubled as a choker. Traditional for bridal pearl malas and ceremonial wear.
Rope / Lariat
Waist-length or longer. Most dramatic. Traditionally worn multi-looped, knotted, or as a sash. Popular for South Indian bridal trousseaux.
Certification — what real documentation looks like
Every pearl piece above ₹10,000 should come with certification. Here's what an authentic certificate includes.
A real pearl certificate must state:
- Pearl type (Freshwater cultured, South Sea cultured, Akoya, Tahitian)
- Exact size in millimetres
- Shape classification (round, near-round, drop, baroque, etc.)
- Colour and overtone
- Lustre grade (High / Medium / Low)
- Surface grade (Clean / Lightly Spotted / Spotted)
- Nacre thickness (for Akoya and South Sea)
- Whether bleached, dyed, or treated
- Issuing lab's name, stamp, and signature
Trusted certification labs:
- GIA (Gemological Institute of America) — gold standard, international
- IGI (International Gemological Institute) — widely accepted
- GJEPC (Gems & Jewellery Export Promotion Council) — Indian
- GSI (Gemological Science International)
- In-house certificates — valid for smaller purchases, not for insurance or resale
