April Birthstone: Diamond

The April birthstone is diamond, crystallised carbon and the hardest natural material, at 10 on the Mohs scale. It is also the traditional gift for a 60th anniversary.

Most diamonds are colourless, but natural diamonds also occur in brown, yellow and other tones. A diamond can be natural (mined) or lab-grown; the two are physically and chemically the same, and we always say which one you are buying.

For April birthstone jewelry we offer 1 ct total lab-grown diamond stud earrings in 925 sterling silver (gold, rose gold or white), the Aries zodiac necklace set with one natural diamond at its brightest star, an IGI certified 10.03 ct lab-grown radiant, and an untreated natural cognac diamond of 5.20 ct.

Frequently asked questions

What colour is the April birthstone?

Diamond is usually colourless (white), though natural diamonds also come in brown, cognac, yellow and other colours.

Are diamond stud earrings good for everyday wear?

Yes. Diamond is the hardest gem, so April birthstone stud earrings handle daily wear well. Check the backs now and then.

Are your diamonds natural or lab-grown?

Both, and always labelled. Our 1 ct studs and 10.03 ct radiant are lab-grown; the 5.20 ct cognac diamond and the Aries necklace brightest-star stone are natural.

Every piece ships free and insured from Toronto, with 30-day returns and exchanges.
