Emerald Price Calculator
There is no fixed price list for emeralds. Value depends on color, clarity, size, origin and treatment, and the gap between a commercial stone and a fine one can be a hundredfold. Use this calculator to see a realistic retail range for the stone you have in mind.
Estimates only. Ranges are compiled from published retail listings and trade sources, and every emerald is priced individually. Prices for the finest stones can exceed these ranges.

Ranges reflect a one-carat Colombian stone with minor oil. Origin, treatment and size move the price, as explained below.
Four factors, in order of impact.
Color
The single biggest factor. A pure, vivid green with slight blue undertone is worth many times a pale or grayish green of the same size.
Origin
Colombian emeralds often sell for two to three times comparable Zambian stones, for their warm, glowing green and long history.
Treatment
Nearly all emeralds are oiled to improve clarity. Untreated stones are rare and command a strong premium, while heavy treatment lowers value sharply.
Size
Price per carat rises with size. A fine 3-carat emerald costs more per carat than a fine 1-carat stone, because large fine crystals are far rarer.
Clarity
Emeralds are expected to have inclusions, known as jardin. What matters is whether they are visible to the eye and how they affect brilliance.
Documentation
A report from a recognized laboratory confirms origin and treatment level, and is the basis for any fair price on a fine stone.
Emerald pricing, answered.
How much is a 1 carat emerald worth?
A 1 carat emerald can range from about $100 for a commercial stone to $15,000 or more for an extra fine Colombian emerald. Most good-quality jewelry stones fall between $500 and $6,000 per carat.
Why are Colombian emeralds more expensive?
Colombian emeralds are prized for their warm, saturated green and centuries of reputation. Comparable stones from Colombia typically sell for two to three times the price of Zambian stones.
Does oil treatment lower an emerald’s value?
Minor oiling is standard and expected. Value falls as treatment increases, and stones with no treatment at all are rare enough to command a significant premium.
Can I trust an online emerald price?
Only with documentation. Ask for photographs and video in natural light, the treatment level, and a laboratory report for any stone of real value.
Do Casa de Esmeraldas stones come with a certificate?
Yes. Stones priced at $5,000 and above come with a GIA report confirming natural emerald, clarity enhancement and origin. Stones under $5,000 are certified by RG Gem Lab in Colombia, directed by GIA-trained gemologist Rodrigo Giraldo. A GIA report can be ordered for any stone on request, at the buyer’s cost.
