I moved to China's jewelry hub — where much of the world's fine jewelry is actually made, so Alya Stone could skip the showroom, the middlemen and the name on top. What you're paying for is the gold and the fine materials. Made to order, made to last.

MORE INFORMATION

The Astra is an ode to what endures. Three lab-grown diamonds — oval, round, and marquise — gather in a composition that jewellers have long called past, present, future.

At centre, a 2-carat oval of exceptional D colour and VVS2 clarity; to either side, a supporting cast of 1 total carat in D–F / VS+ quality. Each stone is cut to Excellent grade, chosen for the way light moves through it rather than simply its weight on paper.

The band measures 1.8mm — substantial enough to anchor the setting, refined enough to disappear beneath it. Four prongs hold the centre stone with quiet precision. Available in 10K, 14K, or 18K yellow or white gold, and in platinum.

Every Astra is made to order. Please allow 10–15 business days for production.

past present future, but sleek

i love the meaning of a three-stone ring, but i wanted something that still looks clean. this one feels sleek and balanced, like it was designed for real life. it also stacks surprisingly well with a simple band.

past present future, but sleek

the astra oval three-stone is the sentimental option that still feels modern. the center oval catches light in a long “sheen” instead of a glitter bomb, which i personally prefer. it photographs really well too.

balanced sparkle across the finger

Astra oval three-stone feels substantial but not heavy. the spread makes it look bigger than a simple solitaire, but it still reads refined.

oval trio, super balanced

balanced, not bulky

oval trio feels artsy

the astra oval three-stone has a really cool cluster feel (the marquise side stone is my favorite part). it looks like something you’d spot on someone with excellent taste, lol. it’s sparkly but not shouty.

three-stone that stacks well

astra oval three-stone surprised me because it doesn’t feel bulky. i can still stack a slim band next to it without everything rubbing. the mix of side stones makes it feel more special than a standard three-stone.

modern three-stone

Haruto S.
three-stone, not too much

the astra oval three-stone feels romantic but still sharp because of the mix of side stones. it doesn’t look like every other “milestone ring.” i’m also impressed how smooth the band feels on the sides — no scratchy edges.

clean trilogy, artsy edge

astra = modern milestone ring

i wanted a three-stone but didn’t want “classic bridal.” astra feels styled and modern—especially that marquise side stone, it’s such a sharp detail.

B
Beatrice M.
three-stone but designed

the Astra oval three-stone doesn’t feel traditional at all—oval center with a round + marquise side stone is such a good combo. i keep noticing different facets in different lighting.

oval center perfection

astra’s center oval is that dreamy elongated shape, and the side stones make it feel “finished” without needing a big wedding band.

G
Grace K.
oval + side stones = glow

I didn’t expect the marquise side stone to be my favorite detail, but it adds this little “leaf” shape that makes the center oval feel even brighter. Photographs beautifully.

L
Li X.
cluster but not chaotic

i’m picky about three-stone rings looking “busy,” but the oval with the round + marquise sides is actually super airy. it catches light differently when i type — little flashes, not disco.
