Why buy a certified sapphire
A lab report gives you an independent record of what the stone is: natural or synthetic, its weight and measurements, and any treatment the lab detected. For an engagement ring or a gift you plan to insure, it is the simplest way to know exactly what you own.
The labs we list
Our Ceylon blue sapphires carry reports from AGL (Thailand). One Thai royal blue sapphire carries a GIA report. Our lab-grown diamond carries an IGI report and is always labelled as lab-grown. The lab is named in every listing title.
Sizes for engagement rings
Most certified sapphires here are between 1 and 2 carats, in ovals and cushions around 6 to 8 mm, a common size for a centre stone. Measurements are listed so your jeweller can plan the setting.

Frequently asked questions
Is the lab report included?
Yes. The report named in the listing is included with the stone.
Are certified sapphires heated?
The report states whether heat treatment was detected. Each listing repeats the treatment so you can see it before you buy.
Do you sell lab-grown sapphires?
No. Every sapphire we sell is natural. The only lab-grown stone in this collection is a diamond, clearly labelled as lab-grown.
