How to join two fields in JSON array with jq

Question

I'm trying to get output in one line for 2 fields in the array using 'jq'

curl -X 'GET' "https://api.coingecko.com/api/v3/coins/ethereum/market_chart?vs_currency=USD&days=10&interval=daily" -H 'accept: application/json'|jq '.prices[][]

gives me output like this:

1652227200000
2344.797715643986
1652313600000
2080.910243657776
1652400000000
1966.6991711336661
1652486400000
2010.214051125259
1652572800000
2064.229357512243
1652659200000
2147.047447880575
1652745600000
2025.8886983912162
1652832000000
2095.178884796724
1652918400000
1915.1771232664505
1653004800000
2023.8482593608173
1653070323000
1931.3963167096579

and I would like output to have date price (in one line) with space or tab in between like

1653004800000    2023.8482593608173
1653070323000    1931.3963167096579

I've tried with '.price[][]|join(" ")' but it didn't work. possibly also format price to have 2 decimal places. I was able to do it if I output only price like:

...|jq .price[][1]| xargs printf "%'.2f\n"

not sure how to do it if I have 2 values.
