The Gem Museum

Gemstones are rounded for lustre, diamonds cut for brilliance. You'll leave knowing why.

For anyone who has stared into a jewellery-shop window and wondered what exactly the price tag pays for, this free museum on Perak Road is the answer, and a better weekday date than it sounds. It is one family's collection, laid out from mine to market, and it feels less like a showroom than a backstage tour of the trade. The compromise is that you can't just turn up: visits are booked in advance and walk-ins aren't accepted.

Whose stones these are

The museum was founded in 2015 by husband-and-wife Tay Kunming and Loke Hui Ying, and it says most of what is on display comes from the private collection of Kunming's father, Tay Thye Sun, Singapore's first certified gemologist and founder of the Far East Gem Research Institute. The family also runs a gem lab and training institute, which explains the depth. It has moved more than most museums: older listings put it on Kandahar Street in Kampong Glam and later on Queen Street, and it is now in a shophouse at 9 Perak Road, its third home, a short walk from Rochor MRT. If a photograph you have seen shows a different interior, that is why.

Mine to market

The route follows a stone through four stages: how it forms, how it is dug out, how it is cut and polished, and how it is traded. You move from geology and the big names (rubies, sapphires, diamonds) to a laboratory with spectrometers where stones are analysed and graded, then to the business end. The details that stick are the small, nerdy ones: gemstones are often rounded to show off lustre and colour, while diamonds are cut for brilliance, and some stones glow under ultraviolet light. A visit could also spare you from a gem fraudster one day, which is only half a joke.

How to do it well

Book a slot online and, if one fits, take a guided session rather than a self-led one; a lab full of spectrometers makes far more sense with someone to explain it. Come with a question, such as why one stone costs a hundred times more than a lookalike. Children tend to head for the rocks. The museum describes a geode-cracking activity and a Junior Rockstars programme for younger geologists, but hands-on activities, the Space Glow Room and workshops cost extra and sit outside a standard visit, so check what your slot includes. On the way out, the shop has a basket of polished stones sold by weight, the cheapest souvenir for a child who has just decided to become a geologist.

It is closed on Sundays and Mondays. Take Exit B at Rochor, and pair it with lunch in Little India next door for a very good weekday afternoon.
