Jadeite Translucency and Color — Icy, High-Icy, Glassy and Lavender Explained

In the jadeite trade, translucency describes how far light travels into a stone before it stops, and color describes the hue, the saturation, and how evenly that color reads across the piece. Words such as icy, high-icy and glassy rank translucency; words such as lavender, vivid green and honey yellow name color. Both sets are descriptive trade vocabulary rather than laboratory measurements. This guide sets out what each term usually means, how we render it in English across this site, and what these words can and cannot tell you before you look at the photographs and video of a particular piece.

What translucency actually describes

Hold a jadeite cabochon in front of a diffuse light and part of that light enters the dome, scatters among the crystals inside, and returns to the eye. How deep and how clean that return looks is what the Chinese trade calls 种水 — roughly texture and water. Two properties drive it: the size of the interlocking crystals that make up the stone, and how tightly those crystals are packed. Finer, denser material lets light travel further with less scattering, so the surface reads deep and wet rather than dry and chalky.

Translucency is not transparency. Very few jadeite cabochons are see-through the way a faceted gemstone is, and none of the words below promise that. What the vocabulary tries to capture is a sense of depth — the impression that the dome has an interior, and that light is doing something underneath the polish rather than only bouncing off it.

Because the effect is made of light, it also depends on the light you are standing in. Daylight near a window, a warm domestic bulb, an office ceiling panel and a phone screen will each give a slightly different reading of the same stone. That is one reason we film every piece as well as photographing it: a video carries the stone through changing angles, which is closer to how it behaves on a hand than any single frame.

The translucency words: Icy, High-Icy, Glassy

Three terms do most of the work, and they describe a continuum rather than three separate boxes.

• Icy (冰种) — the reading most often compared to a piece of ice. Light enters, but the interior looks slightly clouded or granular, with a soft, frosted quality rather than a clear one.
• High-Icy (高冰) — a step further along the same scale. The interior reads cleaner and deeper than icy material, with less visible graininess. The trade uses it for stones that approach glassy but are still described within the icy family.
• Glassy (玻璃种) — the top of the ordinary scale. A very fine, tightly packed texture returns light with little internal scattering, so the dome reads bright and clean.

Two further words describe how light comes back rather than how far it goes in. Glowing, also written as Fluorescent-Glow (起荧光), is a soft bloom that appears to sit just under the polish and to move as the stone moves. It is an optical effect of fine texture and a well-cut dome, not a reaction to ultraviolet light. Crisp-Clarity (钢性) describes the opposite temperament: a hard, tight return where reflections keep clean edges instead of dissolving into a halo.

You will see these words combined, because the trade combines them. A stone can be high-icy and glowing, or glassy with crisp-clarity. Combined names are read left to right: translucency first, then optical character, then color.

The color words

Color terms name hue and saturation, and sometimes the relationship between two colors in one stone.

• Lavender (紫罗兰) — the purple range, from a pale grey-lilac through to a more saturated violet.
• Vivid-Green (阳绿) — a bright, warm-leaning green; the character 阳 means sunny, and the term points to that quality of light in the color.
• Intense Vivid Green (辣阳绿) — the same family pushed harder, with higher saturation and more attack.
• Honey Yellow (黄翡) — the yellow to golden range.
• Russet Orange-Red (红翡) — the warm orange-red to russet range.
• Clear-Green (晴绿, also 晴水) — an even, gentle green over a clean base, valued for evenness and calm rather than intensity.
• White-and-Green (白底青) — distinct green carried on a white or near-white ground, where the contrast is the point.
• Lavender & Vivid Green (春带彩) — purple and green present in the same stone.
• Multicolor (三彩 or 多彩) — three or more colors in one stone.

Color words tell you what a stone is called in the trade. They do not tell you how the color is distributed, how even it is, or how it will read in your own light. Those are questions for the photographs and the video of the individual piece.

Chinese trade terms and our English naming

Our piece names are built from this vocabulary in a fixed order — translucency, optical character, color, then style and piece number — so that two names can be compared against each other. The table below is the mapping we use across the site.

A name such as High-Icy Glowing White-and-Green therefore reads as high-icy translucency, a glowing optical character, and green on a pale ground. You will find the same vocabulary in the listings for rings and earrings, where translucency and color carry most of the character of a small stone.

Why we avoid literal translations

Chinese trade terms hold a great deal of meaning in very few characters, and translating them character by character produces English that either misleads or simply reads oddly. We translate for sense instead.

• 辣阳绿 opens with the character for hot in the culinary sense. Rendering it as Spicy tells an English reader nothing about saturation, so we use Intense Vivid Green.
• 翡 is one half of the word for jadeite. Leaving it untranslated as Fei inside a name such as 黄翡 hands the reader a syllable rather than a color, so we use Honey Yellow, and Russet Orange-Red for 红翡.
• 小灯泡 describes a small cabochon with a strong internal glow. The literal Bulb-Shaped suggests a shape, which is not what the term is about, so we name the optical character directly: Radiant.
• 钢性 describes how hard and tight the light return is. The literal Steel-Clear reads like a claim about material, so we use Crisp-Clarity.

The rule runs in both directions. A name should tell an English-speaking reader what the stone looks like, and a Chinese-speaking reader should recognize the trade term standing behind it. Where the two cannot be reconciled, we choose the description over the transliteration.

Trade descriptions, not laboratory grades

None of these words is a grade. There is no laboratory scale behind them. A gemological report can state whether a stone is jadeite and whether evidence of treatment was found; it does not issue a translucency grade, and no independent body defines where icy ends and high-icy begins.

That makes the vocabulary comparative and, to a degree, subjective. Different sellers draw the lines in different places, and the same stone can honestly be described a notch higher or lower by two experienced people. Treat these terms as a way to narrow a search, and treat the photographs, the video and your own eye as the decision.

The separate question — whether a stone is natural, or has been bleached, filled or dyed — is not a matter of vocabulary at all. That is covered in our guide to natural jadeite and treated jadeite.

How JADE ALL DAY applies this

We use one naming order across the catalog so that names stay comparable: translucency, optical character, color, style, then the piece number. The same vocabulary appears on the English and Chinese versions of every page, which is why the table above exists.

Every piece is documented at our own bench in Stillwater, Minnesota. Each listing carries four or five studio photographs and a video of that exact piece, so the words above can be checked against the stone rather than taken on trust. Each piece is one of one, sold individually, and not restocked once it is gone.

We publish only what we have verified. Where a piece has a recorded natural feature, such as a growth line, we state it on the page and it is visible in the video. Where we have not verified something, we leave it out rather than estimating it.

Browse rings, earrings, bracelets and bangles and necklaces, or see every available piece. For everyday handling and cleaning, read the jade care notes. Orders are Final Sale, so if a question about a particular stone would change your decision, write to us before ordering.
