About Hessonite Garnet as a Gemstone
Hessonite is the orange to cinnamon-brown variety of grossular garnet, coloured by iron and manganese. It is recognised by a characteristic swirled internal texture, often described as treacle or heat-wave, which is diagnostic under magnification. You can read more via gemmological reference, mineral data.
Hessonite forms in metamorphosed limestones and skarns, and is recovered from alluvial deposits in Sri Lanka, which has long been the classic source.

Frequently Asked Questions
What are the exact measurements of this Hessonite Garnet?
This stone measures 12.9 x 10.6 x 8.3 mm and weighs 6.65 carats. Those figures are taken from the stone itself, not estimated from a category average.
What type of setting works best for a trillion cut garnet?
A V-prong setting is essential to protect the sharp corners of the trillion shape from impact. Your jeweller can also use a custom bezel to frame the geometric edges securely.
Is this hessonite garnet durable enough for everyday rings?
With a hardness rating sitting comfortably on the Mohs scale, this stone handles daily wear well when set into a protective mounting. Rings should still be removed during heavy manual work to prevent scratching.
How does hessonite differ from other red garnets?
Hessonite belongs to the grossular species and gets its distinct honey-yellow to brownish-orange colour from trace amounts of iron and manganese. Unlike standard almandine or pyrope garnets, it often features a characteristic warm treacle-like appearance under magnification.
What is the best way to clean this gemstone?
Clean the stone using warm soapy water and a soft brush to remove everyday oils from the pavilion facets. Ensure the mounting is secure before cleaning, and avoid harsh chemical dips.
How long does delivery take, and can I return it?
We contact you directly as soon as your order is placed to arrange delivery, so you always know where the parcel is. Returns are accepted within 7 days of the date you receive the item.
