Lab-Created Asscher-Cut Emerald Necklace with 21 inch Bismark Chain 14kt Yellow Gold

This Lab-Created Asscher-Cut Emerald Necklace pairs a square Asscher-cut lab-created emerald with a 21-inch Bismark chain in 14kt yellow gold, sold as a complete necklace rather than pendant-only. The double-prong setting at the top of the pendant integrates cleanly into the chain construction. The emerald is openly disclosed as lab-created, the stone is real beryl with chromium and vanadium colour (the same chemistry as natural emerald) produced in laboratory conditions rather than mined, sold honestly at a price that reflects its lab origin and the substantial 6.80g of 14kt yellow gold across the necklace.

About the Lab-Created Emerald

The centre stone is a lab-created emerald, also called a synthetic, hydrothermal, or laboratory-grown emerald. Lab-created emeralds are chemically and structurally identical to natural emeralds, both are beryl (beryllium aluminum silicate) coloured by chromium and vanadium, both display the green colour for which emerald is known, and both register 7.5 to 8 on the Mohs hardness scale. The difference is origin: natural emeralds form over millions of years in the earth's crust, lab-created emeralds are produced in controlled laboratory conditions over months. Lab-created emerald is not an imitation, glass, green tourmaline, peridot, and synthetic spinel are imitation emerald materials, but this stone is real emerald produced in a lab. Modern lab-created emerald is a recognised category in fine jewelry and is openly disclosed throughout the trade.

About the Asscher Cut and Bismark Chain

The Asscher cut is a square step-cut with cropped (octagonal) corners, similar in cut style to an emerald cut but with equal length and width rather than rectangular proportions. The cut was developed by the Asscher family in 1902 in Amsterdam and remains a recognised category in fine gemstone jewelry. Asscher-cut emerald is particularly visually striking because the step-cut faceting reveals the colour saturation of the stone more dramatically than brilliant cuts (which prioritise sparkle over colour). The 21-inch Bismark chain is a flat, intricate gold chain pattern with diagonal links, providing a substantial chain to match the pendant rather than a thin daily-wear chain. At 6.80g of 14kt yellow gold across the complete necklace, this is the heaviest pendant necklace in the gemstone batch by metal weight.

Why Choose a Lab-Created Emerald

Lab-created emeralds offer the colour, the chemistry, and the durability of natural emerald at a price tier that natural emeralds of comparable size and clarity rarely match. A natural emerald in Asscher cut at fine clarity and saturation is typically a four to five-figure stone before the setting is added, and the strong colour saturation buyers want from fine emerald is genuinely scarce in natural mined material. Lab-created emerald solves both problems: the chemistry produces strong colour reliably, the lab origin keeps pricing accessible, and the buyer gets real emerald material rather than glass or simulant alternatives. Compare against our natural-emerald pendants if natural origin is important to you, this Lab-Created Asscher Emerald is for buyers who want emerald colour and durability in a substantial 14kt yellow gold setting at a price that fits a midrange jewelry budget rather than a fine-jewelry investment piece.

Frequently Asked Questions

Is this a natural emerald or a lab-created emerald?

This is a lab-created emerald, also called a synthetic or hydrothermal emerald. The stone is real emerald material (beryl with chromium and vanadium colourants) produced in laboratory conditions rather than mined from the earth. It is sold honestly as lab-created emerald, not as natural emerald. The chemical composition, optical properties, and Mohs hardness (7.5-8) are identical to natural emerald.

What is an Asscher cut?

Asscher is a square step-cut with cropped corners, developed by the Asscher family in Amsterdam in 1902. The cut produces what's sometimes called an X pattern when viewed from above, the long, mirror-like reflections characteristic of step cuts (shared with emerald cut and baguette cut, both also step cuts). Asscher cuts are particularly well-suited to emerald because step-cut faceting reveals colour saturation more dramatically than brilliant-cut faceting.

Is the chain included?

Yes. This is sold as a complete necklace, the 21-inch 14kt yellow gold Bismark chain is included with the Asscher-cut lab-created emerald pendant. The Bismark chain is a flat, intricate gold chain pattern with diagonal links, substantial enough to match the pendant rather than a thin daily-wear chain.

Why is the price higher than a typical lab-created stone pendant?

Most of the value here is the substantial 14kt yellow gold construction (6.80g across the complete necklace including the Bismark chain) and the included 21-inch chain. Lab-created Asscher emerald pendant alone would price below this, the chain inclusion and gold weight account for the price tier. Buyers comparing against pendant-only listings should add chain pricing back in for fair comparison.

Will the lab-created emerald change colour or fade?

No. Lab-created emerald is chemically identical to natural emerald, with the same colour permanence, the same Mohs hardness (7.5-8), and the same chemical stability. As with any emerald, avoid hard impact, ultrasonic cleaning, and steam cleaning, the same care guidance applies regardless of whether emerald is natural or lab-created.
