GIL is an independent gemological laboratory at Golden Landmark (near Bugis) founded in 2011 by Mr Mohamed Shabir, whose own description traces a family profession in gems and minerals. The laboratory identifies, grades and certifies gemstones and minerals, and its head gemologist is also a registered appraiser. GIL also runs gemology courses and its site publishes the founder\'s writing on corundum (sapphires and rubies) — a family of stones at the heart of coloured-stone trade in Singapore.
Typical moments: a stone bought abroad whose identity you want confirmed, an inherited piece needing documentation, a coloured stone whose treatment status changes its value, or a purchase where seller and buyer want a neutral third opinion. A laboratory answers what is this? — and JDMIS gemmology education teaches you to ask the question in the first place: which stones are commonly treated, what the instruments show, and what the words on a certificate actually mean.
