Apricot trees are usually able to produce fruit without a pollinating partner, but the "Moongold" variety appears to be an exception to this.

Probably almost any other apricot tree, provided it is a different variety, should be able to pollinate it. The issue will mainly be bloom time. So you will want to identify whether that variety is early or late blooming for an apricot, and find another variety with a similar bloom time.

(In fact, even plum trees should theoretically be able to pollinate it, but in that case the bloom time may not match up, since apricots tend to bloom earlier)

socalnolympia since you seem to know about this topic - will Prunus mume and hardy almonds pollinate? Around here, I'm assuming they will bloom at about the same time.

The almond is 'Nikita's Pride'.

I'm not entirely sure about almond, but I think it is likely almond and apricot may be able to pollinate each other, to be able to result in fruit production on the tree. That is not, however, necessarily the same thing as being able to produce hybrid seed that will be viable.

I did quickly pull up one article, in the American Society for Horticultural Science, where some Chinese claim they made a hybrid between almond and apricot, and importantly it was just regular hybridization (without any special embryo rescue technique).

Hybrids can definitely form between peach and almond, some have been used as rootstocks.
