Detailed Product Description
This Brazilian (Sapota) Emerald (Panna) weighs 4.23 carat (4.65 ratti) and measures 12.20x9.20x5.80 mm, with a green colour and an oval mixed cut. Brazilian origin, declared by Ratna Gems. Tested before dispatch with an authentic gem testing laboratory report included free of charge. Like almost all emeralds in the trade, it is lightly oiled with colourless oil to protect it; a laboratory may record this as minor oil. It is unheated, with no resin and no dye.
Emerald, known in India as Panna or Panna Stone, is the green to bluish green variety of beryl, a beryllium aluminium silicate. Brazil is an established emerald source in the modern gem trade. Sapota is a name used in the Indian trade for Brazilian emerald; on Ratna Gems it is simply the name of this Brazilian Emerald category. Each stone is chosen for its own colour, transparency, clarity, cut and weight.
Appearance
Natural emeralds commonly show inclusions, often called jardin (French for garden) in the gem trade, along with small natural variations in transparency or colour that make each stone individual. Emerald is hard, with fair-to-good toughness, so it rewards a little more care in wear than ruby or sapphire. The photos, video and measurements show this stone's own colour, transparency and look.
Traditional Use
Emerald, known as Panna, is traditionally associated with Mercury (Budh) in Vedic astrology. Customers buying it for astrological use usually follow their astrologer's guidance.
Care
Gentle care keeps an emerald looking its best. Clean it with warm, soapy water and a soft brush or cloth, then dry it carefully. Avoid ultrasonic and steam cleaners, and keep the stone away from high heat, hot water, sudden temperature changes, solvents such as alcohol or acetone, harsh chemicals and hard knocks, which can draw out the protective oil or widen fissures. Tell your jeweller it is an oiled emerald before any setting or repair; if the oil dries over the years, a jeweller can re-oil it.

Frequently Asked Questions
Is this Brazilian Sapota Emerald natural, and is it treated?
Every gemstone is tested before dispatch with an authentic gem testing laboratory report included free of charge. Like almost all emeralds in the trade, it is lightly oiled with colourless oil to protect it; a laboratory may record this as minor oil. It is unheated, with no resin and no dye.
Does Sapota mean a separate emerald variety or grade?
No, it is simply a name. Sapota is used in the Indian trade for Brazilian emerald, and here it names this Brazilian Emerald category rather than a variety, grade, mine or treatment. Each stone is chosen for its own colour, transparency, cut and weight, shown in its photos and video.
Which planet is Panna associated with?
Mercury (Budh). In Vedic astrology, Panna is traditionally associated with this planet. This is a traditional belief, not a promise of any result, and customers usually follow their astrologer's guidance.
How is Brazilian Emerald different from Zambian or Colombian Emerald?
Mainly by source. Zambian emeralds are often described as a cooler, bluish green and Colombian ones as a warmer, pure green, but emerald appearance overlaps between sources, so the best guide is this stone's own colour, transparency, clarity, cut and weight, all shown on this page.
What should I check before buying an emerald online?
Everything you need is on this page: the report's conclusion, the treatment details, the carat and ratti weight, the dimensions, the colour, transparency and cut, and the photos and video. For a ring or pendant, give your jeweller the dimensions and tell them the emerald is oiled before setting; a little gentle care then keeps it looking its best.
