Description of Lot:
The emerald mines of Swat Valley in northern Pakistan continue to deliver some of the most captivating natural gemstones in the world. Known for their vivid color and untouched beauty, Swat emeralds have become highly sought after by collectors, gem cutters, and gemstone investors.
Today’s focus is an impressive 547.30-carat emerald rough lot, featuring a key crystal measuring 12.45 × 14.74 × 11.70 mm. This parcel offers strong potential in both cutting and collection value.

🌄 The Source: Swat Valley’s Legendary Emerald Belt

Swat Valley has produced emeralds for decades, and its deposits are celebrated for:

Rich, grassy to deep green tones

Natural transparency zones

Strong crystal shape and structure

Often untreated, natural rough pieces

Chromite-rich geology that favors vibrant emerald formation

Each piece from Swat carries the essence of the Himalayan mountains—formed naturally over millions of years.

💎 The 547.30ct Rough Lot – What Makes It Special?

Weighing a total of 547.30 carats, this lot is substantial and ideal for both cutters and collectors. It includes multiple rough pieces showing:

Authentic natural crystal edges

Promising color zones

Good transparency sections

Untreated, raw appearance

Highlighted Stone – 12.45 × 14.74 × 11.70 mm

One of the standout pieces in this lot measures:

Length: 12.45 mm

Height: 14.74 mm

Width: 11.70 mm

This is a perfectly balanced crystal, thick enough and deep enough to provide excellent cutting possibilities.

🔍 Breakdown of the Dimensions
Length – 12.45 mm

Suitable for oval, emerald-cut, or cushion shapes.

Height – 14.74 mm

Great vertical depth — allows the removal of surface imperfections while maintaining weight.

Width – 11.70 mm

Enough body to cut a larger center stone or multiple smaller stones.

These dimensions indicate strong potential for producing a sizable faceted gemstone, depending on clarity.

🛠 Cutting & Yield Possibilities

Rough emeralds usually yield 30–55% of their weight after finishing. For a crystal of this size:

Clean zones may yield a 3–7 carat faceted emerald

If fractures exist, a beautiful cabochon or artistic shape is possible

Some collectors may choose to keep the piece raw due to its natural form and origin

The lot also contains multiple medium-sized pieces ideal for step cuts, small faceted stones, or raw crystal jewelry.

Description of Lot:
Emeralds from the Swat region (in northern Pakistan) have long been prized for their vivid green hues and clarity. When a 42 ct rough lot surfaces with individual pieces measuring 6.68 mm, 8.58 mm, and 8.76 mm, it’s worth a closer look. In this post, we’ll explore the possible value, cutting potential, and what gem‑enthusiasts should watch out for.

1. Basic Facts & Context

Total weight: 42 carats (for the rough lot)

Individual sizes: 6.68 mm, 8.58 mm, 8.76 mm

Source: Swat (a historically important emerald mining region in Pakistan)

Swat emeralds are known to often have a bright green color with transparency, though they may come with inclusions typical of natural stones from the region.

2. What Do the Sizes Tell Us?

The dimensions (in mm) of rough stones indicate how large the final faceted gems could be:

6.68 mm — this is relatively small; depending on depth and symmetry, this could yield ~1.0 to 1.5 carat faceted stone (just an estimate).

8.58 mm and 8.76 mm — in the mid‑size range, these have better potential to cut into significant stones, perhaps 2 to 3 carats each, depending on how much internal inclusion or irregular shape one must remove.

However, a lot of rough weight is lost in cutting and polishing (sometimes 40%–60% loss, or more if the rough is irregular or fractured). So from 42 ct total rough, one might expect perhaps 15–25 ct of clean, faceted stones (this is a rough rule of thumb, not a guarantee).
