About JewelPearl

Buying pearls should feel like a pleasure, not a gamble. Yet the questions pile up fast the moment you look closely. Is that lustre worth the price, or is the seller’s “AAA” just a label? What length of strand suits your height, and how many pearls does it even take to make one? What does a jeweller mean by a 7mm Akoya versus an 8mm freshwater, and which size is right for the occasion? How is a loose parcel weighed, and what on earth is a momme? None of it is hard once you know the method — but working it out unaided, every time, is where the joy of pearls turns into second-guessing.

JewelPearl is built around that gap. Rather than long essays you have to wade through, the site is a set of small, single-purpose calculators, each aimed at one real decision. The Pearl Strand Length & Bead Count Calculator turns a finished length and a pearl size into the number of pearls a strand needs, knots and clasp included. The Necklace Length by Height Calculatormatches the classic drape lengths — choker, princess, matinee, opera — to your frame. The Pearl Weight (Momme) Calculator converts between momme, grams, carats, and grains, the units the trade actually uses. The Pearl Value Estimator scales a base price by size and the type and grade factors you supply. The Pearl Grading Scorecard rates a pearl on luster, surface, shape, nacre, colour, and matching for a comparable letter grade. And the Pearl Size Recommender suggests a millimetre size for the wearer and the occasion.

Alongside the calculators, the blog and learnsection explain the ideas the tools rest on — how a natural pearl differs from a cultured one, why luster leads every grading system, what separates Akoya from Tahitian and South Sea, and how to store and clean nacre so it lasts a lifetime. The Pearl & Gem Museum is a browsable collection of pearls, the molluscs that make them, famous jewels, and the wider world of gemology, with every entry, image, and fact drawn from Wikipedia and Wikimedia Commons.

A few things worth stating plainly. JewelPearl is independent and not affiliated with any jeweller, pearl farm, grading lab, or retailer. It is supported by advertising, which is how the tools stay free with no account required. Every figure a tool produces — a bead count, a necklace length, a weight in momme, an estimated value, a grade, a suggested size — is a general estimate based on the numbers you enter and on common pearl conventions, not an appraisal or a certificate. Pearl prices, grading standards, and sizing conventions vary by seller and pearl type, and the tools deliberately ask you to supply your own figures rather than baking one market’s numbers in as fact. For anything with real money riding on it — a valuation, an insurance figure, a major purchase — verify with a qualified, independent appraiser. If a tool looks wrong, or there’s a calculator you wish existed, the contact page is the place to tell us.
