JT
Exactly as pictured, no surprises
★★★★★
Ordered a 2ct oval sapphire for a custom ring and the color match to the listing photos was spot on. Setter said the cut was clean and well-proportioned.
Jason T. — Austin, TXRM
Beautiful spinel, great packaging
★★★★★
First time buying loose stones online and I was nervous, but the spinel arrived in a sealed gem jar with a certificate. Color is even richer in person.
Rachel M. — Denver, CODK
My jeweler was impressed
★★★★★
Brought the peridot in for a bezel setting and my jeweler asked where I sourced it. Clean facets, great symmetry, no visible inclusions.
David K. — Scottsdale, AZSP
Fast shipping to the US
★★★★★
Was expecting a long wait since it shipped internationally, but it landed in six days with tracking the whole way. Tourmaline quality exceeded what I paid.
Stephanie P. — Charlotte, NCMW
Perfect anniversary gift stone
★★★★★
Bought an ametrine for my wife's ring upgrade. The purple-gold split is exactly what she wanted. Will be back for earrings to match.
Marcus W. — Chicago, ILAL
Great for my mineral collection
★★★★★
I collect rare specimens more than jewelry stones, and Gemstones Island's rough-to-cut selection is unmatched. The sphene was a standout piece.
Anita L. — Portland, ORCB
Responsive customer service
★★★★★
Had questions about clarity grading before buying and got a detailed reply within the hour, with extra macro photos of the actual stone. Bought with confidence.
Chris B. — Tampa, FLNH
Stunning citrine, true to photos
★★★★★
The mandarin citrine glows in daylight exactly like the listing showed. Faceting is crisp and it arrived double-boxed with foam padding.
Nicole H. — Seattle, WATR
Second purchase, still impressed
★★★★★
Bought a garnet last year and just picked up a topaz this month. Consistent quality both times and the packaging keeps getting better.
Tyler R. — Nashville, TNEG
Better in hand than online
★★★★★
The amethyst has a deeper purple with a hint of red flash that photos didn't fully capture. Great value for the carat weight.
Elena G. — Miami, FLBW
Trusted seller, easy returns
★★★★★
Wasn't sure about the aquamarine's tone under indoor light, but the return process was painless and the replacement stone they suggested was even better.
Brian W. — Salt Lake City, UTKP
Sourced with real transparency
★★★★★
I asked about origin and treatment history for an emerald and got a straight, documented answer instead of a sales pitch. That's rare in this market.
